Mitigating Bunching With Bus-Following Models and Bus-to-Bus Cooperation

Bus bunching is an instability problem where buses operating on high-frequency public transport lines arrive at stops in bunches. This work unveils that bus-following models can be used to design bus-to-bus cooperative control strategies and mitigate bunching. The use of avoids the explicit modelling bus-stops, which would render resulting discrete, with events occurring arbitrary time intervals. In a follow-the-leader two-bus system, communication allows driver following bus observe (from remote distance) position speed leading same line. information transmitted from leader then follower eliminate A platoon transit line controlled as leader-follower dyads. this context, we propose practical laws regulate speeds, lead cure. combined state estimation scheme developed capture effect disturbances randomness passenger arrivals. To investigate performance schemes 9-km 1-California San Francisco about 50 spaced used. Simulations empirical data are carried out. Results show avoidance improvements terms schedule reliability services delays. proposed robust, scalable network size, thus easy deploy by agencies improve guidance drivers, reduce costs.
