Multistate Coordination and Harmonization for AV Legislation
6/17/2024 12:00:26 PM
Over two-thirds of states in the U.S. have enacted automated vehicle (AV) legislation, an executive order regarding AVs, or both. AV laws and regulations may differ for licensing, registration, operator requirements, equipment, insurance, and platooning, among others. A consistent deployment framework for AV technology and AV regulations among state, local, and tribal territories is necessary so AVs can operate seamlessly. NCHRP Legal Research Digest 91: Multistate Coordination and Harmonization for AV L...
Advancing Highway Traffic Monitoring Through Strategic Research: 2024 Update
6/12/2024 2:00:55 PM
Monitoring travel on the nation's roadways is crucial for understanding the dynamics of the U.S. transportation system. This involves both broad assessments, such as calculating annual average daily traffic to report on vehicle miles traveled, and detailed analyses, like examining freeway operations on a minute-by-minute basis. TR Circular E-C292: Advancing Highway Traffic Monitoring Through Strategic Research: 2024 Update , from the Transportation Research Board, is a collaborative effort of over 60 spe...
PFAS Management at Airports: A Guide
6/3/2024 2:00:08 PM
Per- and polyfluoroalkyl substances (PFAS) are found in many products, from consumer products to building materials. For airports, the primary implication is associated with aqueous film-forming foams (AFFFs) used in firefighting. For many years, airport operators were required to use AFFFs and, as a result of recommended training requirements and fire response, may have had releases of AFFFs to the environment. ACRP Research Report 262: PFAS Management at Airports: A Guide , from TRB's Airport Cooperati...
Risks Related to Emerging and Disruptive Transportation Technologies: A Guide
6/3/2024 2:00:00 PM
Emerging technologies present many potential challenges to state departments of transportation (DOTs) and other agencies that own and manage the existing infrastructure. Significant uncertainty exists about which changes are most likely to occur and where the largest impacts could be, hampering an effective national alignment in policy and approach. NCHRP Research Report 1090: Risks Related to Emerging and Disruptive Transportation Technologies: A Guide , from TRB's National Cooperative Highway Research ...
Improving Rider Safety for Mopeds and Seated Motor Scooters of 50cc or Less
5/30/2024 5:00:55 PM
Relative to passenger cars, two- and three-wheeled vehicles such as motorcycles, mopeds, and seated motor scooters (50cc or less) are associated with a higher risk for fatalities and serious injuries in the event of a traffic crash, as they do not offer the protection of an enclosed vehicle or include other safety enhancement features such as occupant restraints. BTSCRP Research Report 11: Improving Rider Safety for Mopeds and Seated Motor Scooters of 50cc or Less , from TRB's Behavioral Traffic Safety C...
Mitigation Tools for Improving Rider Safety on Mopeds and Seated Motor Scooters
5/30/2024 5:00:20 PM
Relative to passenger cars, mopeds and seated motor scooters are associated with a higher risk for serious or fatal injuries in the event of a traffic crash. However, moped and scooter riders are sometimes not specifically recognized by statewide safety initiatives, as they are sometimes grouped together with related vehicles such as motorcycles. BTSCRP WebResource 2: Mitigation Tools for Improving Rider Safety on Mopeds and Seated Motor Scooters , from TRB's Behavioral Traffic Safety Cooperative Researc...
Developing a Guide for New Mobility Options in Travel Demand Forecasting and Modeling
5/27/2024 2:51:48 PM
The transportation field is undergoing a transformative change in response to several technological innovations resulting in the emergence and widespread adoption of new mobility options (NMOs) such as shared micromobility, transportation networking companies (TNCs), and connected and autonomous vehicles (CAVs). NCHRP Web-Only Document 399: Developing a Guide for New Mobility Options in Travel Demand Forecasting and Modeling , from TRB's National Cooperative Highway Research Program, offers practical gui...
Innovation Programs and Practices of State Departments of Transportation
5/24/2024 7:00:05 PM
The focus on innovation across state departments of transportation (DOTs) continues to grow and strengthen. Unlike research activities, which have established programs and processes, innovation programs are relatively new. DOTs are focusing more directly on innovation, including that related to internal organizational excellence and external program and project development and delivery. NCHRP Synthesis 633: Innovation Programs and Practices of State Departments of Transportation , from TRB's National Coo...
Integrating Performance-Based Planning into Long-Range Transportation Plans and STIPs
5/24/2024 6:00:46 PM
State departments of transportation (DOTs) must develop long-range transportation plans (LRTPs) and State Transportation Improvement Programs (STIPs) as key products of the transportation planning process. DOTs have a long history of developing these documents through many cycles of planning. NCHRP Synthesis 631: Integrating Performance-Based Planning into Long-Range Transportation Plans and STIPs , from TRB's National Cooperative Highway Research Program, documents current practices of state DOTs relate...
New Mobility Options in Travel Demand Forecasting and Modeling: A Guide
5/24/2024 6:00:01 PM
Emerging transportation technologies and shared mobility services, or new mobility options (NMOs), are affecting travel behavior and demand. NMOs may include shared micromobility, transportation networking companies (TNCs), and connected and autonomous vehicles (CAVs). As NMOs grow in availability and use, transportation planners and decision-makers need to be able to understand how to harness positive and mitigate negative impacts. NCHRP Research Report 1113: New Mobility Options in Travel Demand Foreca...
