Book Description
Most large transit agencies have shifted from collecting transit performance data manually to using automated data systems to measure performance. These systems, which include Automatic Vehicle Location (AVL), Automatic Passenger Counters (APC), and Automated Fare Collection (AFC), enable transit agencies to (1) collect larger and more detailed sets of performance data, (2) measure transit performance more from the perspective of customers, and (3) conduct more systematic service evaluation processes. While many transit agencies have adopted these data collection technologies, many have not modified their service planning processes to reflect the full advantages of automated data systems. This thesis evaluates the current performance metrics used by the Chicago Transit Authority (CTA) and the Massachusetts Bay Transportation Authority (MBTA) in their respective service planning processes. A set of recommended performance metrics are proposed in the categories of bus loading, service reliability, passenger demand, and cost effectiveness that take advantage of the benefits of automatically collected data. Next, a service planning process is proposed by which transit agencies can use automatically collected data to systematically evaluate bus transit performance at the route, corridor, and system levels. In addition to making general recommendations applicable to all large transit agencies, this thesis makes specific recommendations for the CTA and the MBTA to improve their respective service planning processes to make full use of the capabilities of automated data systems. This thesis finds that performance metrics which take advantage of the large and detailed data sets that automated data systems provide can more accurately and acutely identify performance problems, leading planners to develop better solutions. Also, the efficiencies in automated data collection compared with manual data collection allow transit agencies to perform a more comprehensive and systematic process by which the performance of all transit service is evaluated on a regular basis. Finally, while automated data systems provide a high level of detail about bus transit performance, contextual information about route operations remains critical to accurately identifying and resolving performance problems.

Book Description
Transit agencies have traditionally used manual data to measure performance and plan service, but many transit agencies now fulfill these tasks by using automated data collection systems (ADCS), including Automatic Vehicle Location (AVL), Automatic Passenger Counters (APC), and Automated Fare Collection (AFC) systems. ADCS enable service planners to make more informed decisions due to the larger, more ubiquitous, and timelier sets of performance data. This thesis evaluates current MBTA bus service in Somerville and Medford using several types of ADCS-based performance indicators. Route profiles are developed for each route in the study area and demand is analyzed for each route and its segments. Archived AVL running times are analyzed and recommendations are produced to improve reliability by adjusting the current scheduled running times where appropriate. This thesis evaluates several service planning scenarios using GIRO Inc.'s NetPlan software package, which is a sketch service planning and timetabling tool linked to its HASTUS automated scheduling system. The outputs of the ridership and running time analyses are used as inputs into bus service scenario planning process. The service change scenarios include implementing even, clock-face headways, utilizing interlining, improving the scheduled running times and layover times, modifying frequencies based on demand, synchronizing routes that serve the same route segments, and incorporating selected changes in routing. The number of buses required to serve each timetable scenario is the primary output of interest. This thesis finds that automated sketch service planning tools, such as NetPlan, can improve the efficiency of timetables by performing thousands of iterations that would otherwise be impractical. In the resource-constrained AM peak, timetabling inefficiencies in the existing schedule were reduced to improve reliability, increase frequencies, and modify routings. The peak period service frequency changes resulted in an expected net passenger wait time and scheduled delay savings of 165 hours. For the most comprehensive timetabling scenarios, interlining was found in 72 percent of the optimized vehicle blocks indicating that transit agencies can create timetables that use highly reliable cycle times and equitable headways based on current route ridership and cost considerations.

Book Description
This synthesis reviews the state of the practice in how data are analyzed. It addresses methods used to analyze data and what computer systems are used to store and process data. It also covers accuracy issues, including measurement error, and other problems including error in estimates. This document from the Transportation Research Board addresses agency experience with different data collection systems, giving attention to management error, the need for sampling, and methods for screening, editing, and compensating for data imperfection. Sample reports from selected U.S. and Canadian transit agencies are reproduced in this synthesis.

Book Description
Running time variability is one of the most important factors determining service quality and operating cost of high-frequency bus transit. This research aims to improve performance analysis tools currently used in the bus transit industry, particularly for measuring running time variability and understanding its effect on resource allocation using automated data collection systems such as AVL. Running time variability comes from both systematic changes in ridership and traffic levels at different times of the day, which can be accounted for in service planning, and the inherent stochasticity of homogeneous periods, which must be dealt with through real-time operations control. An aggregation method is developed to measure the non-systematic variability of arbitrary time periods. Visual analysis tools are developed to illustrate running time variability by time of day at the direction and segment levels. The suite of analysis tools makes variability analysis more approachable, potentially leading to more frequent and consistent evaluations. A discrete event simulation framework is developed to evaluate hypothetical modifications to a route's fleet size using automatically collected data. A simple model based on this framework is built to demonstrate its use. Running times are modeled at the segment level, capturing correlation between adjacent segments. Explicit modeling of ridership, though supported by the framework, is not included. Validation suggests that running times are modeled accurately, but that further work in modeling terminal dispatching, dwell times, and real-time control is required to model headways robustly. A resource allocation optimization framework is developed to maximize service performance in a group of independent routes, given their headways and a total fleet size constraint. Using a simulation model to evaluate the performance of a route with varying fleet sizes, a greedy optimizer adjusts allocation toward optimality. Due to a number of simplifying assumptions, only minor deviations from the current resource allocation are considered. A potential application is aiding managers to fine-tune resource allocation to improve resource effectiveness.
