Three steps toward smarter transportation investments
A new study by SSTI with researchers from the Civil and Environmental Engineering Department at the University of Wisconsin-Madison looks at transportation project prioritization programs at 21 agencies across the U.S. The study identifies three overarching strategies to better align investments with policy goals: 1) establishing flexible funding programs; 2) evaluating key outcomes; and 3) maximizing benefits per dollar spent.
Transportation professionals call for improved standards
As the window closes for comments on the eleventh edition of the Federal Highway Administration’s Manual on Uniform Traffic Control Devices (MUTCD)—the national standard governing all traffic control devices—strong criticism of the manual is coming from industry professionals and safety advocates alike.
Reforming fees and fines could help chip away at transportation inequities
A recent report by the Chicago Metropolitan Agency for Planning (CMAP) highlights transportation inequities in the greater Chicago area. Big-picture findings support the region’s comprehensive plan, but the near-term recommendations focus on changes in transportation-related fees, fines, and fares—a small but important share of overall transportation costs.
Speed limit standards are an essential step toward safer streets
New considerations for setting speed limits have the potential to shift the practice away from the historic norm of service to drivers, and toward the safety and accommodation of all users.
Micromobility in Cities, A History and Policy Overview (National League of Cities, 2019)
Bike sharing—both docked and undocked, manual and electric-assist—plus kick and electric scooters have become commonplace in cities across the U.S. But best practices are still emerging, and cities are often not sure if these new micromobility devices will bring positive or negative consequences to their transportation system and neighborhoods. The National League of Cities has provided a history of the rise of micromobility, a guide for what cities should think about as they move forward with regulation and policy, and finally case studies from across the country.
How and Where Should I Ride This Thing? “Rules Of The Road” for Personal Transportation Devices (Mineta Transportation Institute, 2019)
The Mineta Transportation Institute surveyed various levels of government—cities, states, and college campuses— as well as conducted personal interviews with stakeholders, to detail how jurisdictions are regulating electric and kick scooters, skateboards, e-skateboards, hoverboards, Segways, and rollerblades. They then recommended model state laws to bring some standardization to the use of these personal transportation devices.
Real-time crash prediction models: State-of-the-art, design pathways and ubiquitous requirements (Accident Analysis and Prevention, 2019)
With the advancements in artificial intelligence, and multiple studies being focused towards developing real-time crash prediction models, the concept of a proactive safety management system has become very close to reality. The linked study conducts an extensive review of the existing real-time crash prediction models, systematically illustrating the various methodologies being used world-wide. It evaluates the universality, design requirements, and associated challenges of various models. The study aims to be a “one stop knowledge source” for future researchers and practitioners for transitioning from the existing real-time crash prediction conceptual models to a real-world operational proactive traffic safety management system.
