Cognitive Route Search Technique for Self-Driving Vehicles

2. Route Search For Self-Driving Vhiecles

Currently, congestion is a major problem encountered in real traffic environments across the globe. Some approaches to the problems of traffic congestion have been suggested, including an analysis and improvement of the road through traffic engineering (Amudapuram & Kalaga, 2012), and traffic management through signal control in the Intelligent Transport System (ITS) (Rahane & Saharkar, 2014). We approach the problem of traffic congestion by using a route search technique. When traffic congestion occurs along a route, vehicles can adopt a new route to avoid the congestion.

However, if many vehicles adopt the optimal route, it may cause traffic congestion at a different location. Such a situation can be regarded as a social dilemma (Dawes, 1980) in the field of game theory and social psychology. Individual rational choice does not always correspond with the rational choice for a society as a whole. Thus, the optimal route no longer remains optimal and the route change ends up being a bad decision.
