Using a case study of Pakistan, this study aimed to observe the effect of road type and conditions, trip timing, law enforcement, passenger type, and sociodemographic indicators on distracted driving behavior. The effect of driving experience on distracted driving behavior was also studied as a mediating variable. A questionnaire was prepared, and 501 responses were selected for this study. The PLS-SEM was employed to test the hypotheses of the study. The results showed that all the factors significantly influenced distracted driving behavior except passenger type. Trip timing had the strongest effect, suggesting drivers were more distracted during the daytime, possibly due to the ease of driving enabling environment, followed by significant effects of road type and conditions, age, and law enforcement. However, passenger presence did not significantly impact distracted driving in this study. The results indicate a need for suitable interventions with various stakeholders (policymakers, police, mental health experts, advocates, and community leaders) to raise awareness, change attitudes, and increase risk perception related to distracted driving behavior and its imperilments.</p></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141594815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Incorporating equity into transit performance measures: A disaggregated bus route level approach","authors":"Alexander Tabascio ,&nbsp;Ignacio Tiznado-Aitken ,&nbsp;Christopher Higgins ,&nbsp;Steven Farber","doi":"10.1016/j.cstp.2024.101256","DOIUrl":"https://doi.org/10.1016/j.cstp.2024.101256","url":null,"abstract":"<div><p>Marginalized communities usually experience inadequate public transport services in North America. Within these communities, buses play a vital role in everyday activity participation. Unfortunately, transport services that may advance equity by improving coverage and service for disadvantaged population groups and areas are often overlooked in transit planning since they usually underperform in ridership-based metrics.</p><p>To address this problem, the Toronto Transit Commission (TTC) introduced an equity service policy in 2019 to enhance bus services in vulnerable neighbourhoods known as Neighbourhood Improvement Areas (NIAs). This policy involves augmenting observed ridership counts for buses serving NIAs to improve or protect services for these communities. Although this proposed measure can improve bus services in NIAs, its current form might exclude other equity-deserving riders (EDRs) living outside NIAs, increasing their accessibility barriers.</p><p>Our study uses quantitative and spatial analytical methods to better understand the equity impacts of this service policy change. We propose moving from the aggregate neighbourhood-based approach using NIAs to a more comprehensive and disaggregated person-based approach. First, we create an alternate method that identifies EDRs at the bus stop level using a fusion of census and travel survey data. We then explore the differences in augmented ridership levels created by the two approaches and evaluate whether the augmented ridership levels are likely to result in meaningful service changes using existing TTC service standards.</p><p>We found that 2 out of 3 transit riders in Toronto are equity-deserving, with 72% residing outside NIAs. Our approach reveals increased ridership on routes with many EDRs, which receive minimal augmentation under the NIA-based method. Conversely, if all riders in NIAs are considered EDRs, our approach shows a 19% ridership overestimation equivalent to 35,245 users. Based on these results, we recommend creating a dedicated equity tool with an individual-centric focus, identifying areas with low transit service and high EDR percentages. This tool could then be integrated as an equity perspective into annual bus service planning.</p></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2213624X24001111/pdfft?md5=f1b1c339918428d409efc4aab3ed1e7f&pid=1-s2.0-S2213624X24001111-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141605955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

User satisfaction ratings towards twelve walk accessibility influencing attributes identified in the study are recorded on a six-point Likert-type ordinal rating scale. The study engages a comparative Multi-Attribute Decision Making (MADM) approach comprising three prominent techniques, viz., Relative to an Identified Distribution Integral Transformation (RIDIT), Grey Relational Analysis (GRA) and Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) for analysing the collected perception database and prioritising the attributes based on user satisfaction. The study outcomes identify ‘Extreme Weather Conditions’, ‘Illumination’, ‘Universal Design Considerations’ and ‘Safety and Security’ as the poorly performing attributes based on user perception and require immediate interventions. Spearman’s rank-order correlation analysis is performed to compare the attribute priority ranks derived from the three methods.

The brunt of traffic fatalities affects males and females differently. Studies on assessing gender-wise exposure to road safety are limited in the Indian context. Therefore, an attempt is made to understand the role of gender in fatality risk assessment. The aim is to evaluate the change in exposure to different motorization growth scenarios for males and females. The fatality-risk model is developed based on the interaction between the victim (pedestrian, bicyclist, two-wheeler, car, and bus) and threat (pedestrian, bicyclist, two-wheeler, car, bus, and environment) road users combined with the at-risk distance traveled by modes for Bangalore Metropolitan Region, India. Male and female traffic fatalities are estimated based on the interaction severity between victim and threat modes. The results show that pedestrians, bicyclists, and two-wheeler users are more vulnerable. Both males and females demonstrate an increased risk of traffic fatalities with the rise in the motorization mode share due to the severity of interaction of vulnerable modes with another motorized mode such as two-wheelers and cars. The most significant reduction in road crashes for both genders is observed for the High Bus scenario, which assumes that 80 % of the total motorized distance is traveled by bus. Maximum traffic deaths are estimated for the High Car scenario; the fatalities remained high even with 100 % motorization indicating higher risk with high motorization rates. The study outcomes would help practitioners and decision-makers to make informed policy decisions. Further, the fatality risk is assessed considering the interaction of at most two road users, and the study can be extended to the simultaneous evaluation of multiple road users.</p></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141481558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to model elderly users’ perceived level of satisfaction with bus transit service using the ordered probit model. The study area for our research is the city of Patna, which is the capital of Bihar, India. An extensive perception survey of 416 elderly users populates the database for the present study. According to model estimation results, increasing the number of seats reserved for the elderly and improving the condition of bus stops will increase the perceived level of satisfaction and will lead to attract more elderly passengers to bus transit service. Marginal effects were calculated to evaluate the impact of each independent variable on the perceived level of satisfaction. The overall prediction success rate is 60%.

However, as Sun Moon Lake is surrounded by mountains and has limited land to develop, traffic congestion around the lake area is commonplace during peak holiday hours. This study focuses on the parking choices of visitors to Sun Moon Lake and develops a stated preference (SP) instrument with multiple scenarios to evaluate parking preferences under various financial and service level scenarios. We estimate Multinomial Logit (MNL) and Mixed Logit (ML) models, accounting for the panel nature of the data (PDML)to identify preferences for parking choices of visitors to Sun Moon Lake. The focus is on understanding how parking price, travel time, walking time, scenery, and transfers between public transport affect visitors’ parking choices. Unlike the findings of studies in metropolitan areas, which often find that parking price was the deciding factor, visitors’ parking decisions in the tourist area were more concerned with time factors, such as the time to search for places to park and traffic congestion, possibly due to the less frequent use of tourist venues. Although raising parking price can suppress parking demand in the scenic area, other parking management mechanisms work better, such as the construction of new and suitable outer parking lots with transfer buses to relieve the heavily congested traffic in the scenic area. In addition, we find that using the parking space in the area can be improved by beautifying the landscaping between the parking lots and the tourist spots, enhancing the pleasure of traveling along the routes, introducing multiple transfer modes, and providing real-time traffic information to tourists.</p></div>","PeriodicalId":46989,"journal":{"name":"Case Studies on Transport Policy","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141439212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
