Available in PDF, EPUB and Kindle. Book excerpt: In fall 1983, spring 1984, and fall 1984, PAT (the Pittsburgh regional transit authority) conducted intensive ride checks on selected routes. Data from these ride checks were used to explore issues that remained unresolved by the Bus Transit Monitoring Study, whose Data Collection Design Manual final product was the Transit (TDCDM). This report is divided into sections, each covering one of the following areas: 1. Multi-Year Use of Conversion Factors: 2. Optimal Sizing of Baseline Sample for Conversion Factors: More Flexibility than TDCDM: 3. Effect of Cluster Sampling: 4. Default Formulas for Estimating Correlation: 5. Evaluation of PAT's Proposed Approach toward Meeting Section 15 Requirements...

This book was released on 2000 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2003-01-01 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB Special Report 277 - Measuring Personal Travel and Goods Movement recommends a series of actions the U.S. Department of Transportation's Bureau of Transportation Statistics (BTS) should take to render its flagship surveys -- the National Household Travel Survey (NHTS) and the Commodity Flow Survey (CFS) -- more effective in meeting the needs of a broad spectrum of data users. The report also recommends approaches BTS and its survey partners should adopt to develop more effective survey methods and address institutional issues affecting survey stability and quality. Report Summary published in the October-September 2004 issue of the TR News.

Download or read book Methodologies to Quantify Transit Performance Metrics at the System Level Using High Resolution GPS Stop Level and GTFS Archived Transit Data written by and published by . This book was released on 2020 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applied to entire transit systems, microscopic methodologies often have computational limitations while macroscopic methodologies ascribe artificial uniformity to non-uniform analysis areas. These limitations highlight the need for a middle approach. This dissertation presents a mesoscopic analysis based around timepoint-segments, which are a novel application of an existing system for many transit agencies. For this research, routes are divided into a consecutive group of bus stops with one timepoint at the center. Each timepoint-segment includes all data collected in that segment during one hour of operation. The utilized data sources are widespread and generally available to transit agencies. A methodology for merging and cleaning the data sources is proposed that: first, identifies broken data collection system to flag missing and inaccurate data; second, defines parameters of probability distributions, representative of specific locations, times, and routes, using sufficient statistics; and third, replaces flagged values with a random, but probabilistically representative value. The merged and stochastically cleaned data is aggregated by timepoint-segment to reduce subsequent computational requirements, yet maintains high granularly for statistical analysis after aggregation. The results of linear and non-linear regressions for service durations, at and between bus stops, are presented and discussed. Independent variables were chosen based on previous published literature, but also included several updated classes of variables to provide comparisons for stop types, traffic signals, vehicle interactions, and time-of-day. The coefficients and performance of aggregated models are compared to previously published methods. The results show that factors identified at the microscopic scale (e.g. passenger movements, bus interactions at stops, travel times, travel speeds, unplanned stops, bus bunching, etc.), can be examined in aggregate without lost utility and without the heavy computation burden required to process large microscopic datasets, while also capturing double the variability in the data. Visuals for congestion and headway performance, based on the aggregated datasets, are designed to examine transit performance along a route, between routes, and for specific segments. These visuals are a potentially useful tool for evaluating performance along routes and for identifying areas that may require a closer examination. Additionally, the methods are not computationally intensive and may be easily customized to examine specific locations, times, or feature sets. The methodologies for data cleaning, regression modeling, and performance visuals, provide a foundation for how timepoint-segments may prove useful to researchers and agencies. The aggregated analysis reduces variability caused by singular atypical events, but still preserves enough detail for a robust statistical analysis. Overall, this approach improves realism, which is beneficial for evaluating the key trade-offs ridership, service, accessibility, and costs. Mesoscopic performance measures may help to understand relationship between key factors influencing transit operations, evaluate uncertainty, examine variations in service, determine points sensitive to disruption, quantify congestion costs for users and agencies, and compare travel patterns between different routes, days of the week, and peak versus off-peak travel.
