| 讲座简介： | Despite widespread recognition and availability, school bus use across the United States is declining. As of 2022, the majority of public schoolchildren do not travel to and from school by bus, but rather by private vehicle. This transition generates private and social costs, including increased traffic congestion and additional travel time for parents and guardians. Together, this suggests a disconnect between current school bus service and potential users. To investigate preferences for school transportation, we designed and fielded a survey investigating household preferences for school bus transportation in the Wake County Public School System, the largest school district in North Carolina. By collecting both revealed and stated preference data, we identify trade-offs respondents are willing to make between travel time and delays or cancellations of school bus service. On average, respondents would trade more than one hour of weekly student travel time to avoid a delay or cancellation of service. Leveraging dichotomous choice information, we find survey respondents value their students’ travel time at a rate of roughly $23 per hour per week. Additionally, respondents would be willing to pay $20 to avoid a delay or cancellation of school bus service. To our knowledge, these are the first estimates of their kind related to school bus transportation. |
