busprioritymeasures江阴公交优先举措-urba2000.pptVIP

The comparison of pure technical efficiency纯技术效率比较 We can found: 1.The performance of Inner City lines was significantly higher than RV lines. The reason is that suburban lines are with better running conditions, and more traffic congestions always happen in downtown. In addition, the main passengers flow distribute with the form point-to-point on the line, which increased the transport efficiency. 从中我们可以发现 1.中心城线路绩效水平显著高于中心城区-郊区和郊区线路。 这是由于江阴市郊区线路通行条件优于中心城区，较少收到交通拥挤的影响。中心城区-郊区间点到点直达客流比例大，运输效率高。 The comparison of pure technical efficiency纯技术效率比较 从中我们可以发现 公交优先措施采取前后，公交系统总体绩效水平有了比较明显提升，中心城线路上升0.27，中心城区-郊区及郊区线路上升0.14。 这是由于现阶段采取的公交优先措施主要在中心城区实施，以解决公交通行效率低下的主要矛盾，受益线路多为中心城线路和部分中心城区-郊区线路。因此对中心城区公交线路绩效提升最显著。 We can found: 2. Before and after bus priority measures was taken, the performance of bus system was upgraded obviously, Inner City lines increased by 0.27, RV lines increased by 0.14. The reason is that at this stage the principal problem of inefficient operation for bus system happened in central city, and the bus priority measures were implemented mainly here. Therefore more Inner City lines were benefited, and their performance was enhanced more significantly. Follow-up Research后续研究 1、 Introduce bus GPS data to evaluation system, for the quota description of the external factor. 将公交GPS数据引入评价系统，进行外部因素的定量描述。 2、 Introduce more bus service indices, especially the dynamic indices. 纳入更多的公交服务质量指标，特别是动态指标。 3、 Introduce city scale, geography and climate factors to compare the bus lines’ performance of different cities 纳入城市规模、地理和气候因素，以用于不同城市之间公交绩效比较。 4、 Methods of combining the performance measurement and government bus subsidy. 将绩效评价与政府公交补贴联系起来的方法。 Thanks for your listening! tengjing@ 09-12, 2010 * * * Performance Measurement of Bus Lines Considering the Carbon emissions Dr. TENG Jing Prof. YANG Xiaoguang Mr. ZHU Weiquan Mr. CHEN Yuyi 2010.9.12 考虑碳排放指标的城市公交线路绩效评价方法研究 TONGJI UNIVERSITY Three elements of performance evaluation o
