Centralized Intelligent Traffic Routing in the Light of Disobedience of Drivers

In urban traffic control, centralised intelligent traffic routing techniques aim to plan routes for vehicles from the global point of view, that is, assigning routes to all vehicles not having their routes yet at once while considering some global objective function such as average travel time. Consequently, it might happen that different vehicles might get assigned different routes despite having the same origin and destination. Different routes might, however, entail different costs such as travel time and/or expected fuel consumption. Such differences might, however, motivate drivers to disobey their assigned routes if such routes are more expensive (e.g. take more time and/or more fuel). Disobedient drivers might then negatively affect costs of drivers who obeyed their routes. This chapter will elaborate on how disobedient drivers can affect the quality of the routes and what remedies might be taken to mitigate the problem.
