Handbook for Safe Driving at an Older Age – 2010

The Handbook for Safe Driving at an Older Age has been prepared by the Department of Transportation Planning and Engineering of NTUA under the scientific supervision of Prof. G.Kanellaidis, in the framework of a project granted by the Ministry of Infrastructure, Transport and Networks. The Handbook aims to assist older drivers increase their self-awareness of the effects of age-related changes on their driving safety and of the need to adapt their driving behavior, to assist older drivers improve their knowledge and develop appropriate concern for their own safety, and finally to guide older drivers to make informed driving decisions.

The Handbook was based on self-screening and educational material for older drivers as well as on the results of a study on the driving behavior of active older drivers, aged 65-74, on a freeway in Greece. Issues covered in the Handbook concern safety within the car, safety in traffic, safe practices on freeway, driving and emotion, driving in good condition, driving problems and age-related changes, indications of serious concern about driving ability and general information such as on procedures for driving license renewal, use of public transport and ways of getting around. The Handbook is available both in Greek and English languages. pdf5

Impact of the conversation with passenger, eating and smoking on driver behavior and road safety 2010

A Diploma Thesis titled ‘Investigation of the impact of the conversation with passenger, eating and smoking on the driver behavior and the probability of being involved in an accident by the use of a driving simulator’  was presented by Charalampos Bairamis and Vasileios Sklias in October 2010. From the lognormal regression models developed it appeared that conversation, eating and smoking lead to a statistically significant decrease in speed, while the difficult conversation leads also to an increase in reaction time and decrease in the distance of the vehicle from the right borderline. From the binary logistic model developed it appeared that the difficult conversation leads to an increased likelihood of an incident. In summary, it appears that the lower speed and the deviation to the right of the drivers who have a difficult conversation while driving cannot offset the much greater risk of an accident due to increased reaction time. pdf5 ppt5

Consolidated Resolution on Road Signs and Signals 2010

In September 2010, UNECE published the report “Consolidated Resolution on Road Signs and Signals”. The concept of ‘self-explanatory’ roads encompasses many different elements of the design, layout and operation of the road network. However, this term serves well to illustrate the need to create an environment that can be easily understood and safely operated by all its users. The Road Safety Forum has been mandated by the United Nations General Assembly to review this fundamental area and to make provisions for road signs and signals that are in line with the requirements of ever growing motorization. link

Estimation of fatality and injury risk by means of in-depth fatal accident investigation data 2010

A research titled ‘Estimation of fatality and injury risk by means of in-depth fatal accident investigation data’, co-authored by G.Yannis, E.Papadimitriou, E.Dupont and H.Martensen was published in the Journal Traffic Injury Prevention in September 2010. A fatal accident investigation (FAI) database is used, which includes intermediate-level in-depth data for a harmonized representative sample of 1300 fatal accidents in 7 European countries. The results of this research show that the baseline fatality risk of road users involved in fatal accidents decreases with accident size and increases with the vulnerability of the road user. On the contrary, accident size increases non-fatal injury risk of road users involved in fatal accidents.  doi

Investigation of the impact of road lighting on the frequency and the severity of road accidents 2010

A Diploma Thesis titled ‘Investigation of the impact of road lighting on the frequency and the severity of road accidents’   was presented by Nikolaos Mitzalis in July 2010.This diploma thesis has been awarded with the Ecocity award 2012. Suitably processed data were used from the database of the Department of Transportation Planning and Engineering of the National Technical University of Athens (NTUA) and lognormal regression models were developed. The application of these models led to the investigation of the influence of road lighting and other parameters such as weather conditions, accident type, vehicle type etc. on the number of casualties and injuries. It appears that road lighting contributes to the reduction of the number of accidents and their severity and that this influence increases with the increase of the severity of the accidents. pdf5 ppt5

Towards a European road safety area 2010

In July 2010, EU published the policy orientation on road safety 2011-2020. Road safety is a major societal issue. In 2009, more than 35,000 people died on the roads of the European Union. The cost for society is huge, representing approximately 130 billion Euro in 2009. Therefore, a corehent holistic and integrated approach is needed, taking into account synergies with other policy goals. Road safety policies at local, national, European or international level should integrate relevant objectives of other public policies and vice versa. pdf5

ETSC ranking Greece last before the last 2010

In June 2010, ETSC published the results of the Annual PIN Report. As many as 34,900 people lost their lives in road collisions in 2009, this is still far more than the maximum of 27,000 which the EU set for 2010. Yet it is 19,500 fewer than in 2001 showing great progress has been made across the EU. Since 2001, road deaths have been cut by 36% in the EU27. Comparison of developments up to 2009 show that Latvia, Spain, Portugal and Estonia achieved the best reductions. Greece was ranked last before the last according to the ETSC report. pdf5

Older Drivers’ Perception and Acceptance of In-Vehicle Devices for Traffic Safety and Traffic Efficiency 2010

A paper titled “Older Drivers’ Perception and Acceptance of In-Vehicle Devices for Traffic Safety and Traffic Efficiency” co-authored by G.Yannis, C.Antoniou, S.Vardaki and G.Kanellaidis was published in ASCE Journal of Transportation Engineering. A multitude of new technologies are emerging, many of which are either explicitly targeted to older drivers or expected to benefit them the most. However, these same older drivers are more likely to find adapting to the use of such technologies challenging. Therefore, understanding older drivers’ perception of such devices will allow experts to take the necessary steps to ensure their smoother acceptance and complete success of their deployment. Older respondents are, in general, more supportive of the considered in-vehicle technologies, while female respondents also show a higher willingness to adopt them. doi

The three main killers on the roads 2010

In May 2010, ETSC published a PIN Flash concerning speed, alcohol and the use of seat belts, which are the three main risk factors on the road. Data from the countries that monitor mean driving speeds in free-flowing traffic show that drivers have slowed down appreciably since 2001. Deaths attributed to drink driving have decreased somewhat faster than other road deaths since 2001 in the EU – by about 5.8%. Although obligatory in all Member States, seat belt use in light vehicles in the EU is estimated to be only 88% for front seats and as low as 72% for rear seats. pdf5

Theoretical framework for modeling pedestrians crossing behavior along a trip 2010

A research titled ‘Theoretical framework for modeling pedestrians crossing behavior along a trip’ co-authored by E.Papadimitriou, G.Yannis and J.Golias from NTUA was published in ASCE Journal of Transportation Engineering in April 2010. A topological approach of pedestrian trip characteristics and crossing decisions is proposed, allowing consideration of distinct patterns of crossing behavior along a trip. Specific techniques from the family of discrete choice models are proposed for determining the number and location of pedestrians’ crossings, accounting for the hierarchical and dynamic nature of pedestrians’ decisions along a trip and a field survey method is presented.  doi

Risk and protection factors in fatal accidents 2010

A paper titled ‘Risk and protection factors in fatal accidents’ co-authored by E.Dupont, H.Martensen, E.Papadimitriou and G.Yannis was published in the Journal Accident Analysis and Prevention in March 2010. Two methodological issues were specifically discussed, namely the accident-size factors (the number of vehicles in the accident and their level of occupancy) and the comparability of the baseline risk. It is argued that – although these two issues are generally at play in accident severity analyses – their effects on, e.g., the estimation of survival probability, are exacerbated if the analysis is limited to fatal accident data. doi

Heavy vehicle age and road safety 2010

A research titled ‘Heavy vehicle age and road safety’ co-authored by Z.Christoforou, M.Karlaftis and G.Yannis from NTUA, was published in the Proceedings of ICE – Transport in February 2010. Findings suggest that older vehicles have a 4.5 times higher accident involvement probability in comparison with newer vehicles, while accidents involving older CMVs have a 4 times higher probability of resulting in a fatality. Further analysis suggests that the mean per capita cost to tax payers from CMV accidents surpasses 100A per year, more than half of which is attributed to older vehicles. Measures to mitigate the problem are suggested. doi

Investigation of the impact of mobile phone use to driver behaviour and safety with the use of driving simulator 2010

A Diploma Thesis titled ‘Investigation of the impact of mobile phone use to driver behaviour and safety with the use of driving simulator’  was presented by Leonidas Roumpas in February 2010. Lognormal regression and binary logistic methods were used to investigate the influence of mobile phone use as well as various other parameters on the mean speed and the probability of an accident. From the models application it appears that mobile phone use leads to a statistically significant decrease of the mean speed in urban and interurban environment and to an increase of accident’s probability, probably due to distraction of driver attention and as a result, delayed reaction time at the moment of the incident. It appeared that in rainy conditions drivers did not present different driving behaviour, however, they had a high probability of being involved in an accident. pdf5 ppt5

A research titled ‘A critical assessment of pedestrian behaviour models’ co-authored by E.Papadimitriou, G.Yannis and J.Golias from NTUA by was published in the Journal Transportation Research Part F: Traffic Psychology and Behaviour in 2009. In this paper an exhaustive review of the existing route choice models for pedestrians is presented. The results of this review reveal a lack of an overall and detailed consideration of pedestrian behaviour along an entire trip in urban areas. Moreover, the need for an integrated approach based on flexibility, disaggregation and more determinism is identified. doi

Targets for serious injury reduction 2009

In November 2009, ETSC published a PIN Flash concerning road injuries. Road deaths represent only the “tip of the iceberg” of traffic collisions. For every road death in the EU, at least 44 road injuries are recorded, of which 8 are categorised as “serious”. In Romania, Norway, Hungary and Spain changes in road deaths and serious injuries followed almost a similar pace, in Luxembourg, France, the Netherlands, Bulgaria and Sweden reductions in road deaths exceeded by far the reductions in recorded serious injuries, whereas in Slovenia, Latvia, Ireland and Greece injuries decreased faster than deaths. pdf5

Car telephone use and road safety – A Road Safety Synthesis 2009

Mobile telephone use as a major road safety issue has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. A range of studies conclude that the use of a mobile phone while driving distracts the driver and causes various changes in driving behaviour that negatively affect traffic safety. Driver reaction times are 30% slower when telephoning while driving than driving with BAC levels of 80mg/100ml and 50% slower than under normal driving conditions. pdf5

Speeding – A Road Safety Synthesis 2009

Speeding as a major road safety issue has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Speeding is one of the biggest road safety problems, consisting as a key factor in about 30% of fatal road accidents. It also greatly increases the risk of an accident. Some 40- 50% of drivers drive faster than the recommended speed limit and 10- 20% exceed the limit by more than 10 km/h. Not only does speeding raise the risk of a crash, it also increases the likelihood of severe injuries or death from an accident. pdf5

Post Impact Care – A Road Safety Synthesis 2009

Post-impact care is a strategy which aims to reduce the severity of injury consequences once a road traffic crash has occurred. Post-impact care has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Despite the fact that the cost of years of life lost from road trauma is larger than from cancer or cardio-vascular diseases, the attention paid by health policymakers, by the medical community and by the road safety field to trauma-related care and research has been disproportionately small so far. pdf5

Vehicle Safety – A Road Safety Synthesis 2009

Vehicle Safety has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Improving vehicle safety is a key strategy used in addressing international and national road casualty reduction targets and in achieving a safer road traffic system. Vehicle safety addresses the safety of all road users and currently comprises measures to help crash avoidance and crash protection. Substantial and evidence-based improvements have been made in the last 15 years and research has identified large scope for enhancing vehicle safety further. pdf5

Older Drivers – A Road Safety Synthesis 2009

The road safety problem of older drivers has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Older drivers have the second highest fatality rate. Only the youngest group of drivers (18-and 19-year olds) has a higher fatality rate. Older drivers are not so much a risk to others, but they are at risk themselves. This means that older drivers are not a risk to others’ transport safety, but they are frailer, making them vulnerable to personal injury or fatality risk in the event of a crash. pdf5

Safety Ratings – A Road Safety Synthesis 2009

An introduction to the safety rating systems in use internationally has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Safety rating systems present impartial information on aspects of traffic system safety. Safety ratings in use today are objective tools for the assessment and improvement of aspects of the safety of vehicles, the road network, work-related road safety and international safety performance. Safety ratings in use either predict safety outcomes for given designs or provide a retrospective assessment based on crash data. pdf5

Road Safety Management – A Road Safety Synthesis 2009

The elements of the road safety management system have been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Based on current knowledge, fatal and long term crash injury is largely predictable, largely avoidable and a problem amenable to rational analysis and remedy. Safety is produced, just like other goods and services and the production process is viewed as a management system with three levels: institutional management functions produce interventions, which in turn produce results. pdf5

Roads – A Road Safety Synthesis 2009

Road design has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Many of the basic principles for good road design were developed up to 40 years ago, and are still valid today. Although further refinements have been explored since then, there still remains uncertainty about relationships associated with design details and recent engineering innovations. Road infrastructure should be designed taking account of the same injury tolerance criteria as those developed for vehicle occupant protection and pedestrian impacts, so that roads and vehicles together provide an effective safety system.pdf5

Quantitative road safety targets – A Road Safety Synthesis 2009

Quantitative road safety targets has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Quantitative targets represent the road safety results which a country or jurisdiction wishes to achieve over a given time frame. Targets provide the focus for the national road safety strategy and the level of their ambition drive decisions about coordination needs, legislative needs, funding and resource allocation, promotion needs, monitoring and evaluation, as well as research, development and knowledge transfer.pdf5

Cost-benefit analysis – A Road Safety Synthesis 2009

A Cost-benefit analysis has been released by the European Road Safety Observatory as prepared by the SafetyNet project. A recent road safety impact assessment is used to illustrate the findings of cost-benefit analyses of road safety measures, showing which measures are found to be the most cost-effective. There is still a large potential for improving road safety by using cost-effective road safety measures. Analyses in Norway and Sweden – both of which are comparatively safe countries – suggest that fatality reductions of about 50 % can be realised by applying cost-effective measures. pdf5

Fatigue – A Road Safety Synthesis 2009

Fatigue as a road safety issue has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Fatigue leads to a deterioration of driving performance, manifesting itself in slower reaction time, diminished steering performance, lesser ability to keep distance to the car in front, and increased tendency to mentally withdraw from the driving task. Fatigue is a major factor in a large proportion of road crashes (range 10-20%). A person who drives after being awake for 17 hours has a risk of crashing equivalent to being at the 0.05 blood alcohol level (i.e. twice the normal risk). pdf5

eSafety – A Road Safety Synthesis 2009

eSafety is defined as a vehicle-based intelligent safety systems which could improve road safety in terms of exposure, crash avoidance, injury reduction and post-crash phases. eSafety has been analysed at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. The evaluation of eSafety measures is a young science. However, research in the EU and elsewhere has confirmed that the following measures could make a large contribution to efforts to meet ambitious safety targets. the EU and Member States should establish a monitoring system to evaluate the design, development and implementation of new in-vehicle technologies and their short, medium, and long-term impacts on road safety. pdf5

Alcohol – A Road Safety Synthesis 2009

Alcohol as a major road safety issue has been highlighted at the recently released synthesis of the European Road Safety Observatory as prepared by the SafetyNet project. Alcohol is one of the biggest road safety problems, about 25% of all road fatalities in Europe are alcohol related whereas about only 1% of all kilometres driven in Europe are driven by drivers with 0.5 g/l alcohol in their blood or more. Compared to a sober driver the crash rate of a driver with a BAC of 0.8 g/l (still the legal limit in 3 of 25 EU-member states) is 2.7 times that of sober drivers. Not only the crash rate grows rapidly with increasing BAC, but the crash also becomes more severe. pdf5

Pedestrian behaviour characteristics in urban roads 2009

A Diploma Thesis titled ‘Pedestrian behaviour characteristics in urban roads’,  was presented by Sofia Tourou in July 2009. This diploma thesis has been awarded with the Ecocity award 2010. An experimental process in real road conditions was carried out. A linear regression model was developed to investigate the impact of certain parameters in the walking speed. A binary logistic model was also developed to investigate the impact of the parameters in the pedestrians’ decision on which section to cross and in the route choice. From the models application it appears that the age and the gender of the pedestrian, the low pedestrians’ flow and the choice of the most pleasant route have statistically significant impact to the walking speed. The pedestrians route choice is influenced by the possibility to walk often, the choice of the fastest route and the number of the direction’s changespdf5 ppt5

Traffic incident management 2009

In May 2009, CEDR published a report titled ‘Traffic incident management’. Good incident management is an important goal for all concerned with the management and safe operation of road networks. Research indicates that non-injury incidents contribute substantially to incident-related congestion. The most powerful tool in minimising the impact of incidents is the provision of fast, direct, high-quality information in a standard format that is acceptable across Europe.

Safer cars across the EU 2009

In April 2009, ETSC published a PIN Flash concernig safer cars across the EU. European citizens do not benefit equally from improvements in passive safety as huge differences persist between countries in the market penetration of safe cars. Sweden, Ireland and Norway are the countries with the highest proportion of cars awarded 5 stars for occupant protection among new cars sold in 2008. Hungary, Portugal and Spain are the countries with the highest proportion of cars awarded 3-stars for pedestrian protection, 5 being the maximum, closely followed by Israel and Greece.pdf5

Ιnvestigation of the minimum gap from the vehicle accepted by the pedestrian for urban street mid-block crossing 2009

A Diploma Thesis titled ‘Ιnvestigation of the minimum gap from the vehicle accepted by the pedestrian for urban street mid-block crossing’  was presented by Athanassios Theofilatos in March 2009. A lognormal regression model was developed in order to investigate the influence of certain parameters in the minimum pedestrian gap acceptance. It appeared that the distance from the vehicle, illegal nearby parking that may affect pedestrian’s visibility, the vehicle size and possible companions have statistically significant impact to the minimum gap acceptance. Concerning the choice to cross the road or not, the waiting time and the gap between the pedestrian and the vehicle strongly define his decision.pdf5 ppt5

UNECE – Transport Review 2008

In November 2008, UNECE published the first edition of the Transport Review, dedicated on road safety. Transport, especially road traffic safety, is the area in which global cooperation is inevitable as hundreds of millions of people who travel on the roads every day take a risk. The risk include excessive speeding, driving under the influence of alcohol or other drugs, failure to use seat-belts and helmets, poorly designed or insuffi ciently maintained road infrastructure, and the use of vehicles that are old, poorly maintained or lacking safety feature. People’s safety must be preserved and improved. This can be achieved through the concerted eff orts of several players, public and non-governmental alike. Even though certain achievements are obvious, further improvements should be made. pdf5

Reducing deaths on motorways 2008

In February 2008, ETSC published a PIN Flash concerning motorway safety. Over 3,200 people are killed annually on EU motorways. The number represents just 8% of the total number of road deaths in the EU and has been going down steadily. The motorways are safest in Switzerland, Denmark, the Netherlands and Great Britain, where less than two people are killed on average for every billion km driven. The number of deaths on EU motorways has been decreasing in 2001-2006 by 5% yearly, yet it has clearly tended to increase in Greece, Sweden, Hungary and Slovenia.pdf5

A mixed logit model for the sensitivity analysis of Greek drivers’ behaviour towards enforcement for road safety 2007

A research titled ‘A mixed logit model for the sensitivity analysis of Greek drivers’ behaviour towards enforcement for road safety’ co-authored by G.Yannis and C.Antoniou from NTUA, was published in the Journal European Transport in December 2007. Traffic violations are among the leading causes of road accidents. In this research, the sensitivity of Greek drivers to a hypothetical intensification of police enforcement for speed violations and improper overtaking is analyzed, using stated preference data. It can be argued that while the “typical” Greek driver may not be particularly risk-prone, there are segments of the population that show a tendency to violate traffic laws.pdf5

Measuring accident risk exposure for pedestrians in different micro-environments 2007

A research titled ‘Measuring accident risk exposure for pedestrians in different micro-environments’ co-authored by S.Lassarre, E.Papadimitriou, G.Yannis and J.Golias was published in the Journal Accident Analysis and Prevention in November 2007. A model of pedestrians’ crossing behaviour along a trip is developed, based on a hierarchical choice between junctions and mid-block locations and taking account of origin and destination, traffic characteristics and pedestrian facilities. A complete framework is produced for modelling pedestrians’ exposure in the light of their crossing behaviour. The feasibility of this approach is demonstrated on an artificial network and a first set of results is obtained from the validation of the models in observational studies. doi

Effects of driver nationality and road characteristics on accident fault risk

A research titled ‘Effects of driver nationality and road characteristics on accident fault risk’ co-authored G. Yannis, J. Golias and E. Papadimitriou from NTUA, was published in the International Journal of Injury Control and Safety Promotion in September 2007. Data from the national accident database of Greece were used to calculate accident relative fault risk rates under induced exposure assumptions. A log-linear analysis was then used to examine first- and higher-order effects within three or more variable groups. Results clearly indicate that foreign drivers in Greece are at increased risk. doi

Road casualties and enforcement: distributional assumptions of serially correlated count data

A research titled  ‘Road casualties and enforcement: distributional assumptions of serially correlated count data’ co-authored by G.Yannis, C.Antoniou and E.Papadimitriou from the NTUA, was published in the Journal Traffic Injury and Prevention in September 2007. Road safety data are often in the form of counts and usually temporally correlated. Using the generalized linear model framework, four distributional assumptions are considered: normal, Poisson, quasi-Poisson and negative binomial, and appropriate models are estimated. Monthly casualty and police enforcement data from Greece for a period of six years (January 1998–December 2003) have been used. doi
