A study on the behaviour of vehicle platoons and platoon formation strategies
PhD Completion Seminar by Santa Maiti
Vehicle platooning, a coordinated movement strategy, has been proposed to address a range of current transport challenges such as traffic congestion, road safety, energy consumption and pollution. In the research, while the current literature focuses on platoon control strategies, intra-platoon communication; few areas like the conceptualisation of platooning objects and platoon operations, an analysis of platoon formation and dissolution strategies have remained relatively unattended. To form platoons in an ad-hoc manner, the vehicles have to `speak the same language', which is in current practice limited to vehicles of particular manufacturers. This work aims to fill the fundamental gap of standardisation by developing a formal model of platooning concepts. There is little work done on platoon formation strategies where only tail merge operation is considered. These strategies typically assume a planned formation and decomposition of platoons, mostly at source and destination. In realistic scenarios, however, one would expect platoons traveling in traffic and can be formed and dissolved in an ad-hoc manner where a vehicle can express a merge request when approaching the platoon on the highway from the back, front or the side of the platoon. This research addresses the research gaps by modelling and implementing different platoon formation, dissolution strategies and corresponding platoon operations and analysing their benefits in different traffic scenarios. Overall, the research guides towards efficient formation and dissolution strategies of a platoon.
