The object of research is the process of functioning of a stopping point within the transport-transfer station of urban public passenger transport. One of the most problematic places in the organization of the work of transport and transfer stations is the reduction of unproductive idle time of vehicles. The prerequisite for the occurrence of unproductive idle time is the simultaneous presence of vehicles at a stopping point in excess of its carrying capacity. A qualitative assessment of the level of organization of the stopping point of the transport and transfer station is carried out on the basis of calculating the correspondence coefficient between the actual idle time of vehicles and the duration of productive technological operations. The simulation of the functioning of the stopping point is used in the work. In combination with analytical calculations vehicle’s idle time parameters it is possible to obtain patterns of change in compliance with the actual downtime ratio depending on the level of SP reserve capacity. It is established that the type of empirical dependence of the change in the correspondence coefficient of the actual idle time is logarithmic. The presented dependence differs from existing considering the stochastic changes in the parameters of the incoming route flow. For the stopping point «Metro station Prospect Gagarina», Kharkiv, Ukraine (49.981225, 36.241933) it is determined that at the existing level of capacity:
– correspondence coefficient of the idle time is 0.879;
– average time of unproductive idle of one vehicle – 0.57 min;
– specific weight of non-productive idle time is 13.8 % of the total time of technological operations. The use of established regularities makes it possible to justify the number of service posts. Compared with existing scheduling methods this form determine the suitable number of positions based on the calculation parameters of routing incoming stream that enables efficient use of territorial space of transport-transfer stations.
