In the case of the feeder bus route choice, it is more desirable to choose the route by treating as a single route linked from origin to destination than the whole network. This study is to establish a concept that frames the feeder bus route choice technique for the change of the existing single bus route or the creation of the new feeder bus route. The concept of the feeder bus route choice technique in this study is not to frame the whole bus network but to frame a single route to a unit O-D pair. So, this study has the assumption that does not consider the waiting and transfer time at the bus stop. This system technique consists of the following phases: I) limitation of the road network examined for the study, ii) enumeration of the appropriate candidate routes by the permissive route length, and iii) determination of the optimum bus route by the route evaluation value.

The bus as a feeder trip should supply equality service to the whole community. But in spite of the change of latent demand to the bus by the variety of regional structural change, the existing bus route can not supply effective feeder service. For cope with the latent demand to the bus, this study establish a concept that frame the feeder bus route design system for changing of the existing bus route or creating of bus route. The concept of feeder bus route design system from this study is not to frame the whole bus network but to frame the single route to a unit OD pair. So, this study have assumption that do not consider the wating time at bus stop and transfer time. This system is consist of three phase. First is limitation of examination road network, second is enumeration of a most suitable route, and final is determination of the optimum bus route. However, a precondition is that the necessary time from the origin to the destination is brief, and having many demand.

The variable message sign(VMS) is a facility to smoothen traffic flows and enable safe passing by providing real-time necessary information on roads, weather, transportation, and traffic regulations. The VMS also solves a feeling of uneasiness and gives a sense of psychological security by providing information to drivers. However, the VMS has a strong character of being a non-market product but a public product, so it has not normally been evaluated for its value. This research has evaluated a value of satisfaction level for traffic information users, using a contingent valuation method(CVM). As a result of evaluating the value of satisfaction level for users through division into an urban roadway and an urban highway for the cities where an intelligent transportation system(ITS) has been established, the urban highway had a value of 96.7 won/system and the urban roadway had a value of 76.3 won/system.
