Title:

Operational and Safety Performance of Signage and Pavement Markings for Managed Lanes Using a Driving Simulator

Abstract:

Managed lanes facilities are providing an opportunity to reduce travel time as well as pollution worldwide. In 2013, Puerto Rico built their first ever two lane reversible Dynamic Toll Lane (DTL) facility. The 10.4-mile managed lane, located at the median of the PR-22 freeway, is shared by Bus Rapid Transit (BRT) and passenger cars. Safety issues have been found associated with sudden lane changing and incorrect use of the designated DTL exit. An online survey was developed to gather information and knowledge of drivers in managed lanes facilities. A driving simulator was used to study the safety aspect of driving behavior inside the PR-22 DTL. The University of Puerto Rico at Mayagüez cockpit simulator was used to compare the driving behavior between two configurations of signage and pavement markings. Configuration corresponds to the existing condition of signage and Configuration 2 consists of a proposed treatment of signage and in-lane pavement markings. The information gathered in the online survey was used to develop the proposed treatment. A total of 24 participants drove 6 representative scenarios based in the independent variables traffic flow and time of day. The performance measurement used to evaluate driving behavior was the vehicle Average Lane Position. The results indicated that Configuration 2 (Proposed Treatment) has improved the Average Lane Position variable in at least 67% of the zones evaluated in comparison with the Configuration 1 (Original Signs).
