Study of the maneuverability of a three-link trailer bus train

Abstract

The metrobus or new Bus Rapid Transport (BRT) bus system is the result of the development of the bus public transport network. Compared to the metro, this project has clear advantages: the lower cost of creating a network, the lower cost of rolling stock, mobility, etc. Along with the undeniable advantages of three-link articulated buses and trolleybuses, there are some disadvantages, i.e. the worst maneuverability and stability of traffic compared to two-link ones. In addition, the efficiency of the operation of such machines is closely related to passenger traffic, which can change significantly during the day. Therefore, 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, can become promising. During peak hours, a bus train operates, and during the inter-peak period, each bus is separate (one bus can be parked at a dedicated site). For such a bus train consisting of three buses of the same type (using the example of MAZ-206), maneuverability indicators were determined, in particular, it was shown that with a non-boundary turn, all buses turn at the first stage sequentially, with the third bus running more intensively to the inside of the turn, increasing the second folding angle compared to the first and fourth compared to the third. With a steady circular movement, a road train consisting of three buses MAZ-206 provides standardized values of the overall lane. It is also positive that for buses with standard control systems, their relative angular speed is significantly reduced and the stability of the road train is improved during the turn.
