Evaluation of the Social Cost of Modal Diversion: A Multi-Modal Safety Analysis


PI: Jeremy Sage (WSU), jlsage@wsu.edu
Dates: 01/16/2015 – 06/15/2016

Infrastructure investment by public agencies routinely has a multi-faceted objective. Often, considerable components of these objectives may be viewed as attributable to the goal of increasing the social welfare of the residents of the region and users of the transportation system. Transportation factors related to social welfare or social costs may typically be viewed in terms of pollution, congestion, and safety. The realization of social cost savings or benefits (performance) is largely dependent upon the response functions (how the user responds to a change in the transportation system) of users. Response functions are largely an insight to the economic conditions experienced by the user. This project will develop a reliable and implementable performance evaluation of safety projects that is readily implementable by effected jurisdictions. To achieve this evaluation, the project will draw from literature and implement tactics from several research lines, primarily that of the transportation infrastructure investment, social cost, and modal choice literature.

Determination of Creep Compliance and Indirect Tensile Strength for Mechanistic-Empirical Pavement Design Guide (MEPDG)


PI: Haifang Wen (WSU), haifang_wen@wsu.edu
Dates: 01/16/2015 – 06/15/2016

Pavement condition greatly affects the safety of driver. For instance, the rutting in wheelpath creates hydroplaning which can leads to loss of control of vehicles. The roughness, e.g. potholes, can pose safety hazards to the driver. Therefore, improving the pavement condition by designing cost-effective long-lasting pavement is of paramount importance. The adoptions of Mechanistic-Empirical Pavement Design Guide (MEPDG) align well with this goal, when compared to traditional empirical pavement design.
