Abstract
To realize more efficient utilization of inter-regional public transportation network, it is indispensable to evaluate the transportation network properly. The transportation network has multiple and contradicting social requirements, such as, the improvement of the convenience, the reduction of the environment load, and so on. Therefore, this study develops a method for inter-regional transportation network evaluation method, using mathematical multi-objective optimization. Subjecting to the inter-regional public transportation network in Japan, some optimized pareto solutions composed of frequency of service on each link are calculated by multi-objective genetic algorithm. The results imply that multi modal service supplying among railways, airplanes and express buses can be effective to improve the mobility of the whole inter-regional transportation network and to decrease CO2 emissions simultaneously.
