Abstract
This paper analyzed the present and future method for providing road traffic information, based on the poll that Metropolitan Expressway Public Corporation (here in after called as MEPC) had carried on in January 1997. More than 80% of the drivers who use road information media such as changeable message signs and roadiside radios said their effectiveness. But, 65% of drivers said they were dissatisfied not to get the information of the whole road network and required enhancing the media that can provide personal information such as service with internet and automatic responding telephones. However, the data suggests that new media are not expected to use effectively by only effort of MEPC, but it is valuable for those who are positive to obtain information and have the spirit of self-help.
