Research on Locating of Suburban Freeway off Ramp-Street Terminal

To improve traffic efficiency and safety of freeway main segment and the connected roads, a method on locating of suburban freeway off ramp-street terminal was proposed. Based on analysis of land use within off ramp area, connected roads, function and category of access streets and the intersections, a macroscopic terminal locating method was studied. The recommended microscopic terminal locating approach was established considering access window, access spacing, access connections between terminal and intersections based on investigations and reasonable calculation methods. The method proposed in the paper is simple and practical, which could be a reference for traffic safety improvement of the current off ramp-street terminal.
