The ability of state agencies to track citation, adjudication, and disposition data accurately and effectively is essential for the identification and appropriate adjudication of problem drivers and habitual offenders. Efficient data tracking can provide benefits at all steps of the citation-adjudication process, from providing real-time information and safer roadside stops for law enforcement officers to […]
Street racing on public roads presents significant risks to community safety. It includes behaviors such as excessive speeding, drag racing, street takeovers, and weaving through traffic, all of which endanger drivers, pedestrians, and emergency responders. In addition to immediate safety concerns, these activities can disrupt traffic and undermine community safety and confidence. Street Racing: Prevalence, […]
Before the 1960s, rural communities had little influence over transportation planning, despite substantial state and federal investment in rural infrastructure. Over time, federal policy emphasized greater rural participation, encouraging state departments of transportation (DOTs) to adopt planning approaches in nonmetropolitan areas that engaged communities and local officials. Early efforts focused on consultation with rural officials […]
The Highway Safety Improvement Program (HSIP) and the State Highway Safety Program are federal initiatives designed to improve highway safety and reduce fatal and serious injuries on the nation’s roadways. HSIPs are typically administered by state departments of transportation (DOTs) and may be structured differently across states. The State Highway Safety Program is managed by […]
At present, highway safety planning depends on fragmented, lagging data, forcing SHSOs to rely on information that is two or more years old. This leaves them planning “half-blind,” unable to address current roadway risks or assess intervention effectiveness within the three-year THSP cycle. Telematics Risk Analysis can help SHSOs shift to a proactive planning cycle. […]
In many modern industries, firms compete in differentiated-product markets while relying on complex global value chains for intermediate inputs. In such settings, trade policies such as tariffs on vehicles and parts operate not only through consumer substitution and firm pricing, but also through firms’ cost structures and sourcing decisions. We develop a structural model of […]
Within the last two decades, Machine Learning (ML), the main subfield of Artificial Intelligence (AI), has gained significant momentum across all sectors, driven by a confluence of factors: exponential growth in data generation, advancements in data storage and computing, and innovations in algorithmic techniques. Most notably and recently, the proliferation of deep learning (DL) methods […]
Artificial intelligence (AI) has revolutionized various areas in departments of transportation (DOTs), such as traffic management and optimization. Through predictive analytics and real-time data processing, AI systems show promise in alleviating congestion, reducing travel times, and enhancing overall safety by alerting drivers to potential hazards. AI-driven simulations are also used for testing and improving transportation […]
This guide explains that safety is not just about the trains themselves, but also about how people get to and from stations . Problems often come from poor sidewalks, missing sign age, bad lighting, and busy roads near stations. Children, older adults, and people with disabilities are especially at risk. In some locations, crossings lack […]
More than 2,100 people were struck and killed while stranded or working on the roadside in 2019–2023. Included among them were drivers and passengers who exited disabled vehicles, as well as roadside assistance providers, law enforcement officers, firefighters, emergency medical services providers, and “Good Samaritans” attempting to help them. Slow Down, Move Over (SDMO) laws […]
