Optimal route search to the destination is one of the most important functions of car navigation devices. The development of road traffic infrastructure has made it possible to receive real‐time information of the traffic situation. Route search algorithms for car navigation devices make use of this information to avoid the traffic congestions. Such algorithms should find the new optimal route efficiently...
In recent years, a vast amount of real time traffic information is collected and provided to the travelers as a part of Intelligent Transportation Systems. These information is collected using sensors or detectors etc. set on the road sections and is utilized by car navigation devices to guide the travelers efficiently in the road network, or used to predict the future traffics. However, sometimes...
The optimal route search in car navigation Systems is often considered to be a route search from the origin to destination. Many algorithms have been proposed to search for the optimal route from the origin to destination. However, in real situations several restrictions may need to be considered in the route search like some intersections must be included in the route while some should be excluded...
