The present study identifies the determinants of traffic crashes as well as the role of crash experiences in mode choice when commuting to school in Can Tho, a medium-sized city in Vietnam, based on self-reported travel behavior data. In Vietnamese medium-sized cities, the fatality rate has been reported to be 8% higher than the national rate and 19% higher than in larger cities. In addition, private vehicles account for over 90% of travel demand in these cities due to uncontrolled urbanization and the people inhabiting these cities are dependent on motorcycle as a mode of travel. Motorcycle and bicycle riders are the most vulnerable road users, hence those commuting to school by these vehicles are often at risk for crashes. In the present study, a total of 4,358 samples, categorized by ‘self-driving’ and ‘pick-up’ subgroups, were collected and used in the analysis. Of the 2,227 participants in the self-driving group, 313 persons (14.05%) experienced by at least one crash in the preceding year. In the pick-up group, with 2,131 participants, 193 persons (9.06%) experienced at least one crash in the preceding year. Crash model estimation results indicate that the household location, gender with specific age group, motorcycle license, travel characteristics and population density have significant impacts on different levels of the crash outcome in each group. In the mode share model, variables representing crash prevalence, household size, the mobility sources available in the household (for example, the number of bicycles, motorcycles, or cars), household location, gender with specific age group, occupation levels, trip rate, levels of school travel distance, build environment, and some variables of perception, also show significant impacts on different levels of mode choice outcomes in each group. The present study provides an insightful understanding of the behaviors and perception of individuals taking school trips in a medium-sized motorcycle-dependent city. Our results indicate that the culture of using motorcycles is firmly entrenched among citizens and policymakers should attempt to redesign road infrastructure to ensure the safety of motorcycle users in parallel with improving walking and cycling infrastructure.

本研究根据自我报告的旅行行为数据，确定了越南中等城市芹苴上学时交通事故的决定因素以及事故经历在交通方式选择中的作用。据报道，越南中等城市的死亡率比全国高出 8%，比大城市高出 19%。此外，由于不受控制的城市化，私家车占这些城市出行需求的 90% 以上，居住在这些城市的人们依赖摩托车作为出行方式。骑摩托车和骑自行车的人是最容易受到伤害的道路使用者，因此那些乘坐这些车辆上下学的人经常面临撞车的风险。在本研究中，共有 4,358 个样本，按“自动驾驶”和“接送”子组分类，收集并用于分析。在自动驾驶组的 2227 名参与者中，有 313 人（14.05%）在上一年经历了至少一次撞车事故。在接送组中，有 2,131 名参与者，193 人（9.06%）在前一年至少经历过一次车祸。碰撞模型估计结果表明，家庭位置、特定年龄组的性别、摩托车执照、出行特征和人口密度对每个组别不同程度的碰撞结果有显着影响。在模式份额模型中，变量代表车祸发生率、家庭规模、家庭中可用的移动来源（例如，自行车、摩托车或汽车的数量）、家庭位置、特定年龄组的性别、职业水平、出行率，学校旅行距离的水平，构建环境和一些感知变量也显示出对每组不同级别的模式选择结果的显着影响。本研究对在依赖摩托车的中型城市进行学校旅行的个人的行为和感知提供了深刻的理解。我们的研究结果表明，使用摩托车的文化在公民中根深蒂固，政策制定者应尝试重新设计道路基础设施，以确保摩托车使用者的安全，同时改善步行和骑自行车的基础设施。本研究对在依赖摩托车的中型城市进行学校旅行的个人的行为和感知提供了深刻的理解。我们的研究结果表明，使用摩托车的文化在公民中根深蒂固，政策制定者应尝试重新设计道路基础设施，以确保摩托车使用者的安全，同时改善步行和骑自行车的基础设施。本研究对在依赖摩托车的中型城市进行学校旅行的个人的行为和感知提供了深刻的理解。我们的研究结果表明，使用摩托车的文化在公民中根深蒂固，政策制定者应尝试重新设计道路基础设施，以确保摩托车使用者的安全，同时改善步行和骑自行车的基础设施。
