Intelligent Crossroads for Vehicle Platoons Reconfiguration

Nowadays, urban environments suffer from recurrent traffic jam with associated side effects. One reason of this is the social implicit priority given to personal cars, which are preferred to public transportation systems the main drawback of which is the time and path rigidity. Recently, some alternative transportation systems have been developed based on size adaptable trains of vehicles called platoon. These approaches still suffer from rigid path planning. The paper presents one possible solution to overcome this drawback. The proposal is based on the use of existing crossroads as hubs able to reconfigure vehicles train while crossing. Thanks to this solution, each train component could have its specific path in the public transportation grid. This paper presents also a comparative study of exposed algorithms relatively to a classical traffic light schedule.
