Abstract

To effectively develop road networks under budgetary and time constraints, high-standard arterial expressways in Japan incorporate dual four-lane roads with provisional two-way two-lane (TWTL) sections in areas of low traffic demand. In the majority of TWTL sections, rubber poles are used to partially separate inbound and outbound lanes, but safety risks, including head-on collisions resulting from lane departures into an opposite-direction lane, are considered problematic. To urgently address this situation, wire ropes were installed along some road sections nationwide to verify their effectiveness in preventing head-on collisions. This paper presents a multifaceted evaluation study of the effectiveness of wire ropes on TWTL sections, including drivability, maintainability, and effectiveness in accident prevention.
