The decrease of traffic capacity of a road link due to vehicle stopping for delivery purposes depends on a number of parameters concerning geometric characteristics of the road and the stopping place, traffic flow and composition, vehicle size and ways of loading-unloading as well as the duration and the frequency of stops.  A methodology is developed in this work for the calculation at microscopic level of the vehicle stopping impact to the traffic capacity of urban road links by the quantification of all the above parameters.  This methodology can be useful for the examination of alternative solutions for the management of vehicle stopping and parking in each road link.  The application of this methodology in a number of road links of Athens showed that vehicle stopping impact varies considerably depending on the number of lanes, the length of the link and the stopping frequency and duration and consequently an integrated scheme for vehicle stopping management has to take into consideration favourable and unfavourable particularities of each link.
