This book was released on 2010 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: The implementation of automatic transit data collection via Automatic Vehicle Location (AVL) and Automatic Passenger Counting (APC) systems provides an opportunity to create large, detailed datasets of transit operations. These datasets are valuable because they provide an opportunity to evaluate and optimize transit operations using methods that were previously infeasible and without the need for expensive manual data collection. This thesis develops a methodology to utilize data collected by typical AVL/APC system installations in order to (a) develop advanced performance measures to quantify schedule adherence and (b) automatically determine the causes of poor schedule adherence. The methodology addresses the difficulty that many small to medium sized transit agencies have in utilizing the data being collected by proposing a methodology that can be automated, thereby reducing resource and expertise requirements and allowing the data to be more effectively utilized. The ultimate output of the proposed methodology includes the following: 1. A ranked list of routes by direction (for a given time period) that identifies routes with the poorest schedule adherence performance. 2. Performance measures within any given route, direction, and time period that identify which timepoints are contributing most to poor schedule adherence. 3. Statistics indicating identified causes of poor schedule adherence at individual timepoints. 4. A visualization aid to be used in conjunction with the cause statistics generated in Step 3 in order to develop an effective strategy for improving schedule adherence issues. With this information, transit agencies will be able to act proactively to improve their transit system, rather than wait until they discover problems on their own or hear complaints from passengers and drivers. The methodology is tested and demonstrated through application to AVL/APC system data from Grand River Transit, a public transit agency serving Waterloo Region in Ontario, Canada.

Available in PDF, EPUB and Kindle. Book excerpt: Observing and fixing transit vehicle's schedule adherence problems have always been one of the main priorities of a transit agency, and different approaches have been developed over time to help reflect transit vehicle's performance and where the improvements should be focuses. Unlike traditional performance analysis that generates reports of the bus's performance based on some performance measures such as 'on-time percentage' at each timepoint, in this study, a methodology is developed that uses the on-time performance of individual transit vehicles on each segment of the route to identify systemic problems with the transit schedule and then make recommended adjustments to the schedule for the next schedule period. The output of the proposed methodology in this research study consists of: 1. On-time performance measures for each segment of the route of interest; 2. Recommended changes to the transit schedule. These recommendations can be made under two different assumptions related to transit agency resources. The “Resource unconstrained” approach assumes that there is no constrain on the amount of time that can be added to the schedule. The “Resource constrained” approach assumes that time can be reallocated within the schedule, but the route traversal time must not be extended. The proposed method provides transit agencies with a mechanism to effectively adjust bus schedules to improve on-time performance. An application of the proposed methodology is conducted and tested on Automatic Vehicle Location (AVL) and Automatic Passenger Counting (APC) system records from Grand River Transit which is located in Waterloo Region of Ontario, Canada.

This book was released on 2014 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quality of service in urban transportation networks is determined mainly by the performance of the intersections. In particular, signalized intersections play a significant role in regulating the traffic in urban transportation networks. As a result, it is essential for transportation authorities to have a system, which can locate poorly operating intersections in the network and rank them for potential improvements. In practice, intersection performance is typically evaluated through the use of models such as HCS (Highway Capacity Software) or Synchro. These models estimate measures of performance (e.g. average vehicle delay, queue length, or level of service) on the basis of determinist and/or stochastic queueing theory. Another approach is to directly estimate intersection performance on the basis of delays experienced by vehicles. One source for such data is public transit bus fleets which are equipped with automatic vehicle location (AVL) systems and automatic passenger counting (APC) systems. These systems use GPS to record where and when a bus stops and the duration of the stop. The purpose of this research was to compare the intersection performance measures produced by Synchro and those estimated from archived AVL and APC data. An empirical evaluation was conducted using 28 intersections in the Region of Waterloo. Average delay and queue length were estimated using Synchro and estimated from archived AVL/APC data. The results show that the estimation of mean delay from the two methods are highly correlated. The estimation of queue length show larger differences, and in general, Synchro underestimated the queue length when compared to the AVL/APC data.

Available in PDF, EPUB and Kindle. Book excerpt: The widespread implementation of automated vehicle location systems and automatic passenger counters in the transit industry has opened new venues in transit operations and system monitoring. Metro Transit, the primary transit agency in the Twin Cities, Minnesota region, has been testing various intelligent transportation systems (ITS) since 1999. In 2005, they fully implemented an AVL system and partially implemented an APC system. To date, however, there has been little effort to employ such data to evaluate different aspects of performance. This research capitalizes on the availability of such data to better assess performance issues of one particular route in the Metro Transit system. We employ the archived data from the location systems of buses running on an example cross-town route to conduct a microscopic analysis to understand reasons for performance and reliability issues. We generate a series of analytical models to predict run time, schedule adherence and reliability of the transit route at two scales: the time point segment and the route level. The methodology includes multiple approaches to display ITS data within a GIS environment to allow visual identification of problem areas along routes. The methodology also uses statistical models generated at the time point segment and bus route level of analysis to demonstrate ways of identifying reliability issues and what causes them. The analytical models show that while headways are being maintained, schedule revisions are needed to in order to improve run time. Finally, the analysis suggests that many scheduled stops along this route are underutilized and recommends consolidation them.

Available in PDF, EPUB and Kindle. Book excerpt: Collecting fares through "smart cards" is becoming standard in most advanced public transport networks of major cities around the world. Travellers value their convenience and operators the reduced money handling fees. Electronic tickets also make it easier to integrate fare systems, to create complex time and space differentiated fare systems, and to provide incentives to specific target groups. A less-utilised benefit is the data collected through smart cards. Records, even if anonymous, provide for a much better understanding of passengers’ travel behaviour as current literature shows. This information can also be used for better service planning. Public Transport Planning with Smart Card Data handles three major topics: how passenger behaviour can be estimated using smart card data, how smart card data can be combined with other trip databases, and how the public transport service level can be better evaluated if smart card data is available. The book discusses theory as well as applications from cities around the world and will be of interest to researchers and practitioners alike who are interested in the state-of-the-art as well as future perspectives that smart card data will bring.

This book was released on 2020 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transit schedules are essential planning tools for many passengers – especially for low-frequency services, transfers, or travel decisions made ahead of the time. This underscores the continued importance of accurate transit schedules to passengers. Agencies, on the other hand, also count on reliable travel times and schedule adherence data for timetable and headway scheduling, as well as operational planning, to provide reliable services to passengers. The objective of this study is to develop a tool to identify potential discrepancies between scheduled and observed mean travel times at a stop to-stop level after removing outliers, and to identify potential inconsistencies between scheduled and observed transfer times at the transfer point level. Demonstrations of the tool’s application are provided using data collected from the Central Ohio Transit Authority (COTA).
