With increasing trends and public requests for crosswalks, agencies are seeking resources on best practices and guidance for pedestrian crossings to improve safety, comfort, and consistency of the transportation network. This guidebook provides a comprehensive overview of rural pedestrian crossings for both pedestrians and drivers by examining Minn

The Louisiana Department of Transportation and Development (DOTD) and other agencies continually identify techniques to reduce roadway maintenance and construction costs. One common approach to this task is the introduction of asphalt mixtures with a smaller nominal maximum aggregate size (NMAS) for utilization in roadways. Excessive stockpiles of

This report examines the relationships between the characteristics of transit-oriented development (TOD) and (1) the use of transit and non-motorized modes (walking, cycling, scooting) and (2) local shopping behaviors and behavioral changes during and after the COVID-19 pandemic. The team gathered data from 341 respondents via an online survey and

This project was undertaken to develop tools and guidelines for designing efficient, sustainable, and environmentally compliant salt storage facilities for winter maintenance operations. The project addressed critical issues such as environmental impacts of chloride runoff, optimization of facility design and location, and the development of tools

Roadside litter is increasing in the state of Utah, especially along landfill haul routes frequented by Trash/Recycling Vehicles and Construction Debris Haulers. These "hotspot" areas pose health and safety concerns for the public and for water resources. Litter cleanup creates an added burden for limited state forces, and the cost is shouldered by

The western massasauga (Sistrurus tergeminus) and the timber rattlesnake (Crotalus horridus) are protected under Nebraska Statute 37-801-811 and listed as threatened species. These species occur in the right-of-way (ROW) along several roads in Jefferson, Gage, Pawnee, and Richardson Counties which necessitates the need for added Environmental Revie

This study evaluates recent technology that uses inductive loop detectors, traditionally used for collecting traffic volume and speed data, to provide vehicle classification data by examining the high-resolution signature produced when a vehicle passes over the sensor. The project aims to verify the accuracy of the new classification system, collec

The implementation of e-ticketing in Iowa has the potential to improve jobsite safety, save time, improve project documentation, and standardize data collection.
Public works agencies at state and municipal levels have invested a large amount of personnel and funding resources in dashboards to improve winter maintenance operations. The types and amounts of data gathered and performance measures used to track and monitor winter maintenance operations vary by agency. Due to these differences, there is a need

Effective traffic incident management is critical for road safety and operational efficiency. Yet, many transportation agencies rely on predominantly reactionary methods, where incidents are reported by human agents and managed through rule-based frameworks like traditional Traffic Incident Management (TIM) systems. These methods, however, are vuln

Running red traffic signals is a major cause of traffic collisions and resulting injuries and fatalities. Despite extensive prior work on systems to reduce red light violations, they continue to be a major problem in practice, partly because existing systems suffer from the flaw of providing the same guidance to all drivers. As a result, some viola

The objectives of this project were to identify the causes of the premature failure of Florida's green-colored pavement markings (GCPMs) and to produce guidelines and improved specifications for the future installation and testing of new GCPM materials. The researchers reviewed relevant literature, interviewed contractors and vendors, visited exist
