Using New Data to Improve Transit Networks

shutterstock_172414874

The transportation ecosystem is changing rapidly. Individuals have new transportation options, and nationwide trends show transit ridership in decline . New technologies, such as automated vehicles, are expected to continue to reshape mobility in the future. In this environment, transit system owners and operators are seeking to adapt their network design and services. Improved data availability and new processing methods can identify ways to improve transit service. Compared to rail systems, bus networks can be altered at relatively low cost to accommodate changes in demand. Bus network revisions include large-scale overhauls, such as recent redesigns in Houston and Columbus , as well as incremental approaches to bus network change, such as route additions, deletions, and realignments. To make these changes, planners need to understand how the current system is used and where there is potential for improvement. In recent years, contactless smart card-based automatic fare collection (AFC) systems have become...

New Data and Techniques for Transportation Economists

CV-blog-graphic1.jpg
Highway link speed data from vehicle GPS probes has become the standard for performance measurement, available free to state DOTs through the National Performance Management Research Data Set (NPMRDS). This data can add value across transportation planning and policy-making. At EDR Group, we think it extends the potential for informed economic analysis. For Missouri DOT, EDR Group conducted benefit-cost and economic impact analysis of an Incident Management System (IMS) on the rural sections of I-70 and I-44. To evaluate the impact of MoDOT’s proposed IMS, we needed to understand the pattern and costs of incidents along the rural highways. To do so, we used vehicle speed data from HERE. We queried 5 years of speed records at 15-minute intervals for every link on rural I-70 and I-44: approximately 143 million rows of data in total. That’s a lot of data!  Figure 1 Schematic of incident identification. Using heuristics and a...
