Influence of Traffic Information Media on Drivers' En-Route Diversion Behaviors

The key success factors of ATIS (advanced traveler information system) depend not only on the good hardware design but on the recognition of drivers' heterogeneity of preference about traffic information. This paper reports on a study undertaken to investigate media used for traffic information provision. A survey was conducted at eight locations near Seoul, Korea, at tollgates. The eight survey points are places which normally experience congestion but also have good alternative roadway choices well known to the public. The results showed that drivers relied more on the traffic information provided than on his or her previously acquired experience on the highway under consideration. Additionally, they used traffic information broadcasting radio during the high peak event period like Chu-seok (Korean Thanksgiving Day), whereas they normally followed variable message sign (VMS) based traffic information during highly congested weekend period. The authors conclude by calling for the increased employment of methods which can lead to higher usage of active information media.
