碩士 / 國立交通大學 / 交通運輸研究所 / 88 / The research is aimed to compare light rail transit and exclusive bus lane based on two items, the cost and the performance. The systematic and operational characteristics in running a light rail transit is taken into account in estimating the input and output quantity of the system. Reasonable cost per unit is substituted for such purpose to get the construction and operation cost of the system. The finding is then compared with Taipei Bus Routes'' existing operational costs.On the performance aspect, the research attempts to evaluate the impacts that both transportation modes could have on its respective users and non-users, based on information obtained from the actual application of the two systems in both the domestic and international regions.Finally, the research compares the applicability of light rail transit and exclusive bus lane from the point of views of operator, the government and the whole system.
Operators are found to support the exclusive bus lane, which has a lower cost per kilometer compared with the light rail. It''s noted that bus lanes incur no additional construction costs for bus operators, but could lower the operational costs of bus systems, hence generating more revenues for the operators.Similar results were found when evaluating from the point of view of the government. Light rail transit, though might help to improve public transport service and cut down air pollution, poses the threat of worsening existing road traffic and spoiling the city image. On top of that, the construction cost for light rail transit is relatively higher than that of the exclusive bus lane, which could help upgrade existing bus service level and improve road traffic on the whole. Hence, the government will favor the bus lane over the light rail.From the overall point of view of the whole system, light rail transit is preferred to exclusive bus lane when the transit volume exceeds 8,550 passengers per direction per hour, with the passenger-kilometer cost of light rail transit found lower than the exclusive bus lane''s.On the performance aspect, light rail transit beats exclusive bus lane in terms of service level, transportation capacity, and operating speed, besides improving the air quality. The conclusion is that exclusive bus lane will only provide short-term solution to existing traffic problems, but could not improve the public transportation service and air quality in the long run. Therefore, from the overall point of view of our society, construction of light rail transit is more beneficial plan in the long run.
