Development and Deployment of Public Transport Policy and Planning in Taiwan

Over the past decade, the escalating roadway congestion and environmental deterioration due to heavy use of private vehicles have provoked the Taiwan government to realize the importance of public transport systems. Under the “carrot-and-stick” rationales, the government has formulated public transport policies and exercised a series of related initiatives by providing sufficient and higher quality of public transport services so as to attract more private vehicle users. In this paper, the planning philosophy and policy formulation of Taiwan’s public transport development are highlighted. The most important initiatives, including the Five-year Enhancement of Mass Transportation Program and the upgrading public transport schemes in the National Development Plan are examined. Based on previous experience and lessons, we point out the most challenging issues that the government will encounter. Suggestions for the future of public transport planning are also addressed.     

Aggregate expenditure elasticity for transport and communication in Australia

For the purpose of estimating Engel elasticity, one needs to find the best functional form among various alternatives. In this paper, a new function, which is called the double semi-log Engel function turns out to be the best functional form for the transport and communication items in Australia on the basis of the distance function (D²) criterion, and the non-nested hypothesis testing procedure. This function is then used to estimate total expenditure elasticity, and the percentage change in consumer demand due to changes in total expenditure and total expenditure inequalities; using the 1975–76 Household Expenditure Survey data. The results of the analyses demonstrate that transport and communication is a necessary item in Australia on the basis of two criteria, viz., its elasticity is not significantly greater than unity, and the percentage change in demand increases with a decrease of the total expenditure inequality [emphasised by Iyengar (I960)]. Policy implication of the analyses has also been discussed.

基于火场信息的地铁车站智能疏散技术研究

火灾是城市轨道交通车站内影响最为严重的事故之一,科学合理的安全疏散方案是突发火灾时确保乘客出行安全的重要保障。然而,目前地铁车站火灾疏散方案中的疏散路线难以根据火场情况动态调整。针对地铁车站疏散路径固定单一的弊端,基于地铁车站内的监控系统,利用计算机视觉技术识别人员分布信息和火灾发生位置,建立空间拓扑模型,利用改进的蚁群算法规划出耗时最短且转弯次数较少的疏散路线,实现站内乘客更科学高效的疏散,最后通过3个场景的案例应用验证本文所提疏散方法的有效性。
