| Summary | The heavy traffic in urban areas usually is a major problem to many countries. It reduces the efficiency of energy and increases the load of air pollutants. Many countries develop different kinds of Transportation System Management (TSM) strategies to solve the problem. TSM strategies are short-term but low-cost solutions to improve the efficiency of function of existed traffic facilities in urban areas. Furthermore, they can also lower the energy use and decrease the air pollution. In this research some arterials of Taipei city are chosen as cases to study the effects of TSM strategies. Five TSM strategies, included bus lane, signal coordination, one-way street system, area license, and reversible lane are selected for the purpose. The effects of the traffic with and w/o five TSM strategies are compared. By using local traffic characteristics and transportation management model, this research simulates some traffic major of effectivenesses(MOE's, such as traffic travel speeds and traffic flow combinations) in each street. The relationships between MOE's and fuel consumption/air pollution are also found in this research. Finally energy consumption, air pollution emission and cost-effect in different TSM strategies are estimated and compared. The results showe that not all of the effects of the five TSM strategies are positive; some are negative. |
