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...

Planning for Rapid Technological Change in Transportation and Mobility Services

shutterstock future2
Hardly a day passes without websites, newspapers, and TV news trumpeting our entry into an era of “self-driving cars” and “smart everything.” More and more, our everyday lives are digitally connected and facilitated, enabling us to shop from our phones, have up-to-the-minute travel information, and instantly share information with anyone, anywhere. As the digitization of our society grows and computing power becomes more portable and affordable, we continue to rush headlong into a future of both technological promise and societal challenges. Within this context of technology-enabled and driven innovations and opportunities, the nation’s transportation needs are similarly rapidly evolving. The advances in information technologies and business processes are enabling new forms of integrated transportation services that span multiple modes providing both passenger and freight services. At the same time, planners and researchers need to recognize that the rapid pace of technological change and digital information systems in transportation is occurring...
