До питання вибору рухомого складу в системі BRT

Abstract

Over the past decade, in the countries of America, Turkey and in some European countries, the Bus Rapid Transport (BRT) system has been developing as a new type of passenger transportation, which involves the movement of buses along specially designated and often fenced lanes, that is, its complete isolation on the road from other modes of transport To increase passenger capacity in the BRT system, three-link buses and trolleybuses are used. Along with the undoubted advantages of three-section articulated buses and trolleybuses, they also have disadvantages of worse maneuverability and driving stability in comparison with two-section ones. In addition, the operating efficiency of such machines is closely related to the passenger traffic, which can vary significantly during the day. An analysis of the organization of transportation shows that a road train consisting of two (or three) buses or trolleybuses operating in a coupling, the passenger capacity of which is similar to articulated buses and trolleybuses, may become promising. During peak hours, a bus train operates, and during between-peak periods, each bus operates separately (one bus can be parked at a designated area). Conducted theoretical studies have proved the expediency of using a three-link trailed road train in the BRT system, consisting of three MAZ-206 buses of the same type with a total length of up to 26 m and a capacity of up to 220 passengers. Calculations have proven that the power of two engines is sufficient for the movement of such a road train in the entire speed range, that is, one of the buses can be used as a passive trailer, which will lead to an improvement in the fuel efficiency of the bus train. It was theoretically established that in terms of maneuverability, a three-link trailed road train significantly exceeds a three-link articulated bus.
