Objectives
1. To establish quantitative safety assessment methods for decision support in transportation planning, policymaking, and management and engineering by integrating safety evaluation into traditional TSI, trip behavior modeling, and supply-demand equilibrium theory. 2. To develop a transportation network-level safety performance function (i.e., meso CPM) using Bayesian spatiotemporal and hierarchical modeling techniques in which a variety of factors related to the regional road network, road entities, traffic flow, and human-vehicle systems are accounted for. 3. Based on decision-making optimization theory, to upgrade TSA methodology to integrate the objectives of both transportation efficiency and traffic safety to establish inherently safe and efficient transportation networks.
