The Technical Decision for Transportation Management System by KUANG YANG KOU ASSOCIATE PROFESSOR DEPARTMENT OF TRAFFIC SCIENCE IN CENTRAL POLICE UNIVERSITY 1
Background： 1. Impact： economy, air quality, energy use, land use, and quality of life. 2. Resource： finance ; fund. 3. Management：effective way balanced transportation systems that serve the diverse population equally. 2
Objectives： 1. Develop monitoring systems that provides data on which subsequent analyses, evaluations, and objective decision-making is based. 2. Create performance evaluations that assemble all the benefits, costs, and impacts of alternatives, so that informed judgments can be made concerning the merits of alternative actions. 3. Identify improvement strategies comprising of broad transportation choices available for evaluation. 4. Create a state-of-the-art decision support tools for prioritizing, programming, and implementing projects. 3
