Considering the importance of rail transportation in the State of Florida, large number of highway-rail grade crossings, fairly frequent occurrence of accidents at highway-rail grade crossings, and traffic delays caused by warning devices at highway-rail grade crossings, this project will assist Florida Department of Transportation (FDOT) with the following primary objectives: (1) Develop a multi-objective optimization model that can assist the FDOT personnel with identification of highway-rail grade crossings that have to be upgraded and selection of the appropriate upgrading type, considering the existing budget constraints. (2) Analyze resource allocation decisions under conflicting objectives (i.e., minimize the overall hazard severity at highway-rail grade crossings vs. maximize passenger and freight flows). (3) Develop a standalone application, which deploys the proposed multi-objective optimization model, in order to facilitate decision making. (4) Conduct a set of case studies to demonstrate some important managerial insights from resource allocation among the highway-rail grade crossings in the State of Florida, given conflicting nature of the objectives considered. (5) Improve safety of highway travelers in the State of Florida by reducing the potential hazard of highway-rail grade crossings. (6) Ensure continuity of passenger and freight flows, reduce delays at highway-rail grade crossings, support economic development, and ensure prosperity of the state. |
