Does Transit Service Reliability Influence Ridership?, Srinivas S. Pulugurtha, Raunak Mishra, Sravya L. Jayanthi
Mineta Transportation Institute
This research focused on analyzing the association between transit service reliability indicators and ridership. Further, the effect of road network, demographic, socioeconomic, and land use characteristics on transit service reliability was analyzed. The analysis was conducted at a bus stop level. Bus arrival/departure and ridership data from the Charlotte Area Transit System (CATS) was obtained. The road network, demographic, socioeconomic, and land use characteristics were captured within 0.25-mile and 0.50-mile buffers. Pearson correlation analysis was conducted to understand the association between road network, demographic, socioeconomic, and land use characteristics and bus transit service reliability measures. The results show that bus …
Community Transportation Needs And Willingness To Use Shared Micromobility: A Case Study Of Fort Smith, Arkansas, Anthony Michael Kammerer
Community Transportation Needs And Willingness To Use Shared Micromobility: A Case Study Of Fort Smith, Arkansas, Anthony Michael Kammerer
Civil Engineering Undergraduate Honors Theses
Shared micromobility is utilized in “targeted service areas with the usage generally intended for short trips such as "first- and last-mile" connections to complete trips made via other modes, including transit” (Price et al., 2021). In the United States, this practice has especially taken off with the implementation of sharing-based systems. This is evidenced by ridership numbers in the United States growing from 84 million riders nationwide in 2018 to 136 million riders in 2019 (NACTO, 2020). Users often use their smart phone or another similar device to unlock the vehicle after paying a fee on the device through their …
Cross-Checking Automated Passenger Counts For Ridership Analysis, Simon Berrebi, Sanskruti Joshi, Kari Watkins
Cross-Checking Automated Passenger Counts For Ridership Analysis, Simon Berrebi, Sanskruti Joshi, Kari Watkins
Journal of Public Transportation
Due to concerns about data quality, Automated Passenger Counting technology has rarely been used to analyze local ridership trends. This paper presents a novel framework to test the consistency and completeness of passenger count data in four cities. The data are aggregated at the system level and compared with the National Transit Database between 2012 and 2018. In all four agencies, passenger counts closely follow the fluctuations observed in the national transit database. There is, however, a slight drift in two of the four agencies. At the stop-level, missing and duplicate vehicle-trips are identified using schedule data from the General …

Communities around the world are gradually becoming aware that transit riders, and especially women, are often victims of a wide range of offenses of a sexual nature that happen on buses and trains, and at bus stops and train stations. Better understanding the extent and nature of sexual harassment on transit is a critical issue for transit operators and society at large. If fear of sexual crime limits if and how people ride transit, the result is reduced mobility for certain segments of the population, as well as lost ridership for transit agencies.
For this study, we surveyed 891 students …

Transport Logistics Of Transit Potential Of “Uzbekistan Temir Yullari” Jsc, U.N. Ibragimov, O.T. Aliyev, M.M. Tohirov
Journal of Tashkent Institute of Railway Engineers
Uzbekistan occupies an important geostrategic position in Central Asia, through the territory of which the Great Silk Road, where numerous trade routes converged, was in ancient times, and an intensive process of mutual enrichment of the cultures of the peoples of the world was under way. And today, there are crossroads of transport routes leading from the East to the West, from the South to the North. For us, the task of preserving a place in international transport with the purpose of developing the efficiency of transportation must be urgent.
Ridership Ramp-Up For Fixed-Guideway Transit Projects: An Evaluation Of Initial Ridership Variation, Jill Elizabeth Shinn
Ridership Ramp-Up For Fixed-Guideway Transit Projects: An Evaluation Of Initial Ridership Variation, Jill Elizabeth Shinn
Master's Theses
Performance-based planning and programming has increased in popularity for transit project funding in recent years. This methodology focuses on quantitative performance measures to inform decision making. For transit projects, projections or observed ridership is the most commonly used performance measure to evaluate project benefits. Conventional wisdom within the transit industry suggests that measuring the performance of a transit project immediately after project opening may not capture all the project’s benefits, since it takes time for a project to realize its short-term ridership potential, a process commonly referred to as ridership ramp-up. While this idea is both intuitive and appealing, especially …
Intersection Signal Control And Design For Improved Person Mobility And Air Quality In Urban Multimodal Transportation Systems, Farnoush Khalighi
Intersection Signal Control And Design For Improved Person Mobility And Air Quality In Urban Multimodal Transportation Systems, Farnoush Khalighi
Doctoral Dissertations
Alternative geometric designs (e.g. roundabouts) and multi-objective signal control strategies are promising measures to improve sustainability of traffic networks. However, roundabouts are mostly used because of their safety and operational advantages. There has been less attention to the environmental performance of roundabouts. Also, the existing studies have been mostly used through field measurements and current simulation models, which need high calibration efforts and they are not inclusive in terms of considering all influencing factors on vehicular emissions at roundabouts. Furthermore, the existing real-time signal control strategies do not account for the emission rates of different vehicle types (e.g. cars and …

Assessment Of The Potential Of Proposed Stations Of The California High-Speed Rail As Major Hubs For Physical And Economic Development, Seitu Akira Coleman
Master's Theses
This study investigated the potential for development of station catchment areas around the proposed California High-Speed Rail System. The study was prompted by a review of practices of Japanese railway company groups that engage not only in train operations, but also in business diversification and property development within the station areas of their lines. These actions allow the company groups to diversify their revenues streams, increase ridership on their lines, and operate as a whole with net profits. This is in contrast to transit agencies in the United States, which only focus on transporting passengers along their lines and do …

Models And Solution Algorithms For Asymmetric Traffic And Transit Assignment Problems, Donghyung Yook
Models And Solution Algorithms For Asymmetric Traffic And Transit Assignment Problems, Donghyung Yook
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Generally, modeling is a simplified representation of the real world; however, this research adds value to the modeling practice by investigating the asymmetric interactions observed in the real world in order to explore potential improvements of the transportation modeling. The enhanced representation of the transportation system by the asymmetric transportation equilibrium problem is promising because there are various asymmetric interactions in real transportation such as intersections, highway ramps, toll roads and in the structure of the transit fares.
The dissertation considers the asymmetric interactions of flows in the traffic and transit assignment problems with an efficient solution algorithm. The study …

Faculty of Engineering and Information Sciences - Papers: Part A
Amorphous silicon (a-Si) electronic portal imaging devices (EPIDs) are x-ray detectors frequently used in radiotherapy imaging and dosimetry applicatioins. EPIDs employ a copper plate and gadolinium oxysulfide phosphor screen with an array of a-Si photodiodes to indirectly detect incident radiation. In this study, a previously developed Mote Carlo (MC) model of an a-Si EPID has been extended for transit dosimetry.
Applications Of Transit Signal Priority Technology For Transit Service, Frank Anthony Consoli
Applications Of Transit Signal Priority Technology For Transit Service, Frank Anthony Consoli
Electronic Theses and Dissertations
This research demonstrated the effectiveness of Transit Signal Priority (TSP) in improving bus corridor travel time in a simulated environment using real world data. TSP is a technology that provides preferential treatment to buses at signalized intersections. By considering different scenarios of activating bus signal priority when a bus is 3 or 5 minutes behind schedule, it was demonstrated that bus travel times improved significantly while there is little effect on delays for crossing street traffic. The case of providing signal priority for buses unconditionally resulted in significant crossing street delays for some signalized intersections with only minor improvement to …

An Overview Of U.S. Commuter Rail, Timothy J. Brock, Reginald R. Souleyrette
Kentucky Transportation Center Research Report
Planners view commuter rail as a means of managing urban sprawl, stimulating economic development and reducing the environmental impacts of transportation. Commuter rail systems, which use shared rights-of-way to connect suburban hubs with downtown urban centers, are beginning to have a large impact on the way people and freight move through US cities. Currently, there are 26 commuter rail systems operating in 29 major U.S. metropolitan areas. However, there is confusion among the general public and disagreement among transportation organizations as to what constitutes a commuter rail system and how to classify some rail systems. This research establishes a complete …

The Role Of The Law In The Availability Of Public Transit And Affordable Housing In Atlanta’S West End, Elliott Lipinsky
ELLIOTT LIPINSKY
The Federal Transit Administration (FTA) is a branch of the U.S. Department of Transportation that administers federal funds and provides technical assistance for the support of locally operated public transit systems. MARTA / Atlanta metro area are part of FTA Region IV (the Southeast). FTA would be involved, for instance, in financing the federal grant monies discussed above. But actual regulation of operations (i.e., what MARTA does each day, or what MARTA will plan to do regionally) is more closely regulated by Georgia agencies.
Until recently, the Atlanta metropolitan area had no powerful central agency to coordinate regional transit. The …
