The effects of transit ridership determinants can be quantified as demand elasticities which are often used to inform transit planning and policy making. This study seeks to determine the impacts of transit service supply, fare, and gas prices on ridership by quantifying the short-run and long-run demand elasticities, as well as test whether transit ridership exhibits an asymmetric response to the rise and fall of these factors using a panel data of 99 Canadian transit agencies over the period of 2002–2016. The results of the dynamic panel model show the effects of transit service and fare to be greater in the long run. The short-run fare elasticity was found to be –0.24 while the long-run elasticity was –1.1. Furthermore, the demand elasticity with respect to service levels was also found to be inelastic (0.28) in the short run but elastic (1.3) in the long run. The cross-elasticity of gas prices was estimated to be 0.17. The existence of asymmetry was analyzed using decomposition techniques to separately estimate the coefficients for the rise and fall in each of the determinants. The equality of these coefficients was tested against each other and it was found that ridership responded more to an increase in transit supply than a decrease. The importance of these results to policy making are then discussed.

可以将过境乘车率决定因素的影响量化为需求弹性，该需求弹性通常用于指导过境规划和政策制定。这项研究旨在通过量化短期和长期需求弹性来确定过境服务的供应，票价和汽油价格对乘车率的影响，并测试过境乘车率是否表现出对这些变化的不对称响应使用2002年至2016年期间99个加拿大过境机构的面板数据得出的影响因素。动态面板模型的结果显示，从长远来看，公交服务和票价的影响会更大。发现短期票价弹性为–0.24，而长期票价弹性为–1.1。此外，关于服务水平的需求弹性在短期内也没有弹性（0.28），但有弹性（1。3）从长远来看。天然气价格的交叉弹性估计为0.17。使用分解技术分析不对称性的存在，以分别估计每个行列式中上升和下降的系数。对这些系数的相等性进行了相互检验，发现乘车人数对过境供应增加的反应多于减少。然后讨论了这些结果对决策的重要性。对这些系数的相等性进行了相互检验，发现乘车人数对过境供应增加的反应多于减少。然后讨论了这些结果对决策的重要性。对这些系数的相等性进行了相互检验，发现乘车人数对过境供应增加的反应多于减少。然后讨论了这些结果对决策的重要性。
