Analysis and assessment of the regularity of mass urban passenger transport in the conditions of the city of ruse

One of the quality indicators of the transport service in passenger transport is the regularity of the movement of vehicles. Apart from the planned traffic intervals, it depends on a number of factors related to the traffic conditions of the public transport in the locality (intensity and composition of the traffic flow, passenger traffic structure, traffic lights regime, atmospheric conditions, etc.). The paper assesses the regularity of mass urban passenger transport traffic in the conditions of the city of Ruse, Bulgaria, by probing the estimation of the arrival intervals of the means of transport at the stops along a given route.
