Book excerpt: The 2013-2014 Indiana Mobility Report: Summary Version examines the mobility performance of Indiana's state highway system. Minute-by-minute crowdsourced probe vehicle speed data and vehicle volume data were used to develop performance measures that identify, quantify, and visualize the location and duration of congestion on Indiana Interstates. The summary report presents overall system performance, including a monthly overview covering January 2011 through June 2014 as well as selected highlights of significant projects. In addition to the Interstate system, the report characterizes selected high-priority arterial corridors to rank their mobility performance in terms of travel time and travel time reliability.

Book excerpt: The 2011 Mobility Report—Full Version introduces the use of crowd sourced probe data collected from vehicles and mobile devices to quantify the location and duration of congestion on Indiana interstates. The report presents a detailed case study presented of the I-65 corridor, as well as examples of travel time reliability information for sections of Interstates 65, 70, and 94. Summary monthly mobility statistics for all 943 centerline miles of Indiana Interstates 64, 65, 69, 70, 74, 94, and 465 are tabulated in a graphical format to facilitate comparison of mobility along those corridors. The report contains three appendices. Appendix A details the location of congestion pockets on each corridor. Appendix B provides quantitative summary of congestion for each interstate by month and direction. Appendix C provides travel time reliability statistics along three corridors in northern Indiana, twelve corridors in central Indiana, and four corridors in southern Indiana.

Book excerpt: This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, sets out requirements for travel time reliability within a performance-based planning process. The research includes an effort to determine the economic value of improvements in travel time reliability by applying options theory from the financial sector. The report includes two succinct tables that describe requirements for person and freight trips for reliable transport, as well as a forecast of the year 2030 under alternative assumptions that may influence travel time reliability.

Available in PDF, EPUB and Kindle. Book excerpt: The Moving Ahead for Progress in the 21st Century Act (MAP-21) defined requirements for system reliability performance measures. Under MAP-21, state departments of transportation are responsible for reporting travel time reliability and for setting targets and showing progress toward those targets. In order to know how to improve travel time reliability and what to expect from investments in transportation infrastructure, these agencies need a better understanding of the factors that affect travel time reliability and methods to predict future travel time reliability. The purpose of this study was to quantify the factors influencing travel time reliability and investigate how to account for these factors in setting reliability targets and communicating progress. To achieve these objectives, this study developed models to estimate quantiles (the 50th, 80th, and 90th) of travel time distributions to quantify the effects of travel time reliability impact factors and predict select reliability measures. First, linear quantile mixed models (LQMMs) were built using both data maintained by the Virginia Department of Transportation (VDOT) and crowdsourced event data. Model results using the crowdsourced data were unstable and difficult to interpret because of data quality issues such as unbalanced spatial density, duplicate reporting, and inconsistent event classification because of individual observer bias. The results using VDOT-maintained data were more reliable and interpretable. Those models showed that frequencies of non-recurrent events, such as incidents and weather, were correlated with higher travel time percentiles. The LQMM was compared with the trend line approach, a common prediction method used in practice, and the results showed that LQMMs significantly improved the accuracy of predictions over the trend line approach based on mean absolute percent error. Generalized random forest (GRF) models were also tested as an alternative prediction method. GRF models improved the prediction accuracy over LQMMs for the 50th and 80th percentiles, but the accuracy was slightly worse for the 90th percentile. In addition, the GRF models could also reflect the impact of variables that were removed from LQMMs because of insignificance, such as the presence of safety service patrols. Before-after studies were conducted to illustrate the application of LQMMs and GRF models. LQMMs captured the changes in the 90th percentile travel times better, and GRF models captured the changes of level of travel time reliability better in most cases. GRF models were more sensitive to the reliability changes caused by non-recurrent events, such as incidents or work zones, and could reflect the impact of variables that were removed from LQMMs because of insignificance. The study recommends that VDOT use the GRF model for predicting travel time reliability on interstate highways. In addition, further research is recommended to extend the GRF models to meet the requirements of MAP-21 federal target setting.
