| Abstract: |
| Overcrowding has become a non-negligible issue for metros in China. This paper analyzes the impact of crowding in metro carriages on people’s travel behaviors based on the stated preference survey data from college students and full-time workers in Guangzhou. The data were analyzed by using the constant-value-per-trip model and the travel time multiplier model with the multinomial logit modeling technique. Results show that there is a significant impact of crowding in metro carriages on passengers’ welfare. The relationship between the disutility of crowding and the standee density is not linear. Commuters do not care much about crowding in the metro, whereas non-commuters and college students pay special attention to crowding in metro carriages, especially when the carriage is crowded. This paper presents new findings of the impact of demographic characteristics on the evaluation of crowding in metro carriages in developing countries. |

| 地铁车厢内拥挤度影响研究——以广州地铁为例 刘建荣 （华南理工大学 土木与交通学院，广州 510641） 创新点说明：论文放弃了车厢内拥挤度效用与车厢内拥挤度是线性关系的假设，对不同拥挤度下的时间价值进行了研究，同时分析了通勤者、非通勤者、大学生在不同拥挤度下的时间价值。 研究目的： 地铁车厢内拥挤度、出行者类别对出行行为选择具有重要影响，为此本文分析地铁车厢内拥挤度、出行者类别对出行者出行选择行为的影响。 研究方法： 研究采用离散选择模型，数据利用陈述性偏好调查得到。 研究结果： 基于陈述性偏好调查得到的数据，利用离散选择模型进行分析发现，地铁车厢内站立乘客的密度与时间价值呈现非线性关系。当出行者从有座到无座时，时间价值增加块多；当站立乘客密度从1人/m2到4人/m2时，时间价值变化不大；当站立乘客密度超过到4人/m2时，时间价值随着站立乘客密度增加而显著增加。此外，通勤者、非通勤者、大学生在同一拥挤度情况下，时间价值有较大差异。 结论： 在分析出行者出行选择行为时，应考虑地铁车厢内拥挤度以及出行者类别对出行选择行为的影响。 关键词：拥挤度；站立乘客密度；陈述性偏好；负效用；地铁 |
