碩士 / 國立中央大學 / 通訊工程研究所 / 96 / Safety and comfort applications have been two popular research topics in ITS
recently. In this paper, we propose a vehicle-based intelligent routing method to
integrate safety and comfort services in Vehicle Route Guidance Systems (VRGS).
By detection, communication and control technologies, it can reach a complete
vehicle route in safe and efficient way, and we discuss advanced in hidden conflict
path problem that some of centralize routing method might be meet.
. A heuristic algorithm for multiple vehicles routing problem called intelligent
routing method is propose, base on greedy routing and detour routing switches
dynamically, then controller can design a near-optimal route for vehicle. Dynamic
detour scheme improve unevenness traffic density condition by balance scheduled
vehicle routes and increase road utility rate; Backtrack reroute process use to correct
unsafe conflict path problem, in addition, it adjust the access traffic flow liked ramp
control in congestion condition. Cooperative drive and Backtrack reroute process to
provide safety warranty by collision avoidance; Dynamic detour scheme provide the
efficiency warranty by detour path selection; under safe and efficient route planning
of globality, the limited transportation resources can be utilized most effectively.
In simulation, it indicate the following verification: First, the different size of
traffic topology to make critical density different; Second, dynamic detour scheme
can balance unevenness traffic, it make traffic system to reach equilibrium and
efficiency; Third, Backtrack reroute process can adjust the access traffic, thus traffic
will not to collapse.
