A field survey involving interviews with 50 passengers and direct observations of hazardous acts was carried out at the bus stops. Casual factors of hazardous acts were noted as well. A score survey was conducted with 17 experts (civil engineers and transportation engineering researchers) where they were asked to rate how much each casual factor contributes to its corresponding hazardous act using a scale of 1–4 (1 being ‘not important at all’ and 4 being ‘very important’). Experts were also asked to make pairwise comparisons among hazardous acts and consistent responses were analyzed using Analytic Hierarchy process (AHP). Results from the score survey and AHP were used to model the safety levels of the selected bus stops. With safety levels ranging from 2.38 to 4.83 (10 being the best and 0 being the worst), all bus stops fell short of an acceptable level of safety. Also, Interviews conducted revealed passengers’ dissatisfaction with their user-experience. Recommendations were therefore made based on the findings.</p></div>","PeriodicalId":47173,"journal":{"name":"Journal of Public Transportation","volume":"24 ","pages":"Article 100003"},"PeriodicalIF":12.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1077291X22000030/pdfft?md5=d2019f7e171c3953e2f098d8eadf4a9d&pid=1-s2.0-S1077291X22000030-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"54976767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One question about the demand response feeder transit operation is whether it can be optimized with door-to-door service or with temporary stops for picking up and delivering passengers. Obviously, door-to-door service eliminates passengers’ walking distances, but it increases passenger in-vehicle travel times and vehicle operating distance and costs. On the other hand, demand responsive feeder transit with temporary stops, which designates the temporary locations picking up and dropping passengers, minimizes bus operating distance and time as well as passenger in-vehicle times, although it increases passengers’ walking distances and times. The developed model uses metaheuristic approaches, including two main algorithms; a passenger’s clustering algorithm based on Particle swarm optimization (PSO) approach and a vehicle routing algorithm that uses simulated annealing (SA) solving method. The algorithm developed an optimal algorithm for clustering and grouping of passengers considering their physical locations and time windows then it was integrated with the authors’ previously developed algorithm for the optimal flexible feeder bus routing as a mixed integer model that objects to minimize the total costs including both passengers traveling times and operator’s operating costs The results of this study showed that although feeder networks with temporary stops always lower operating costs and lessen in-vehicle travel time compared to those with a door-to-door option, the total costs and optimal routings are highly sensitive to the location of passengers.</p></div>","PeriodicalId":47173,"journal":{"name":"Journal of Public Transportation","volume":"24 ","pages":"Article 100021"},"PeriodicalIF":12.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1077291X22000212/pdfft?md5=7deb5c3d22cfcb7d53529ba0234dd942&pid=1-s2.0-S1077291X22000212-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"54977535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a new bus rapid transit (BRT) service, CMAX, in Columbus, Ohio, USA, as an example, we compare its impact on ridership based on a pre-post and quasi-experimental analysis framework. We conduct the pre-post analysis using a ridership space-time cube exploring a massive Automatic Passenger Counter (APC) database. Differences in total passenger counts before and after the BRT intervention indicate a 36% increase in ridership within its corridor. However, this patronage increase may not be attributable solely to the new public transit service. Potential confounding effects include systemwide ridership trends and a new unlimited transit pass program for downtown workers. To address these issues, we adopt a quasi-experimental study design with a difference-in-differences (DiD) identification strategy. We use propensity score matching (PSM) to match a counterfactual control group with the treatment group when implementing DiD model. After accounting for confounding effects, we find a less than 5% increase but not statistically significant impacts of CMAX on ridership. Our results support the argument that a simple pre-post analysis ignoring confounding effects can lead to a misleading evaluation of a new public transit service’s direct impact on ridership.</p></div>","PeriodicalId":47173,"journal":{"name":"Journal of Public Transportation","volume":"24 ","pages":"Article 100035"},"PeriodicalIF":12.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1077291X22017350/pdfft?md5=6e56bfaa3a8d46d593d7b3e7d8db2086&pid=1-s2.0-S1077291X22017350-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"54978029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After developing three independent models, we found the same three latent variables (LVs), namely subsystems “condition”, “service”, and “safety/security”, in each one. However, the strength and significance of the direct and indirect effects among the three LVs vary from one subsystem to another. In general, satisfaction is initially based on a person’s perception of the subsystem’s condition and ends with his/her perception of the service, with safety and service being the mediating variables to explain satisfaction. Unlike previous studies, we were able to identify relationships among these three independent variables for each subsystem, allowing us to assess the direct and indirect effects on overall subsystem satisfaction. This research provides decision-makers with a broader understanding of how infrastructure, vehicles, operational attributes, and regulation processes influence user satisfaction through perceptions and how they can help improve the PT service for its users.</p></div>","PeriodicalId":47173,"journal":{"name":"Journal of Public Transportation","volume":"24 ","pages":"Article 100037"},"PeriodicalIF":12.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1077291X22017775/pdfft?md5=eab218c4d2f8be1017dc9df3bc76c534&pid=1-s2.0-S1077291X22017775-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"54978079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In all four agencies, passenger counts closely follow the fluctuations observed in the national transit database.

We use confirmatory factor analysis to construct four latent variables representing respondent attitudes: safety confidence, software security concerns, technology familiarity and interest, and preference for human control. Then, we estimate levels of adoption using a structural equation model-based multigroup analysis. We find that individuals in pilot cities not only demonstrate greater acceptance of driverless shuttle programs but also have different determinants of acceptance compared with those in non-pilot cities. Notably, the effects of local transit access on driverless shuttle acceptance vary between pilot and non-pilot cities.
