Developing high standard road networks along the beach for tourists would provide convenient, speedy, and safe travelling together with beautiful views and convenient facilities. Tourists can travel beside the beautiful beaches on the eastern seaboard viewing both existing and new places. As a result, it would enhance the tourism industry and generate increasing revenues for local communities. The objective of this study is to survey traffic volume along the tourism beaches on the eastern seaboard between Rayong and Chonburi. It develops a model for traff ic analysis to predict current and future traffic and to support a design for road structure and its facilities. Initially, the study was conducted by reviewing the literature related to traffic volume and the transport system. It surveys traffic on travelling roads. The result shows that in five areas traffic volume can be expected to experience congestion, and consequently will have an impact on future tourism. It also reveals that if there is no development of the roads and facilities studied, the level of service (LOS) would worsen to first level or second level in the next decade. Therefore, developing the area and travelling roads would expand the road surface for traffic and provide additional facilities.
