Filter by Keyword55 report(s) found with highways in the keywords field Annually, many injuries and fatal crashes happen on local rural roads in North Dakota. The local road safety program (LRSP) strategy has been proven effective in reducing crashes on these roads. It relies on state engagement with local stakeholders to collectively reduce crash injuries in their communities.... Mitigating congestion at urban traffic system intersections following major hazards and incidents is a crucial step to maximize the evacuation, rescue and recovery efficiency and prevent a hazard from turning into a disaster. An optimized traffic signal design strategy can effectively contribute to maintaining... Understanding the condition of roadway assets is important for transportation agencies to plan for future improvements and asset management purposes quantitatively. Since these assets are distributed across the country, a manual data collection system falls short of the automated methods due to time... Urban traffic networks consisting of partially blocked roads often need to remain open to traffic before, during, and after disasters because of their vital roles to hazard preparation, emergency response, and recovery of urban communities. Conducting effective traffic planning of disrupted transportation... Green stormwater infrastructure (GSI) is increasingly used to reduce stormwater input to the subsurface stormwater network. This work investigated how GSI interacts with surface runoff and stormwater structures to affect the spatial extent and distribution of roadway flooding and subsequent effects on... This report discusses the design and implementation of surcharging technology and the required laboratory, field, and engineering evaluations. It is hoped that such information will provide a more consistent and technically defensible rationale for deploying this technology on highway projects constructed... This study presents the application of the Highway Safety Manual (HSM) to rural state highways in South Dakota and provides important guidance and empirical results regarding how to calibrate HSM models. Calibration guidelines have been developed to facilitate future calibration activities. The calibration... Highway project selection and scheduling are traditionally treated as two separate problems in the literature. It is critical to investigate how to select and schedule M&R projects in a way that can maximize their benefit or effectiveness while minimizing the traffic impacts of work zones across project... Highway assets, including traffic signs, traffic signals, light poles, and guardrails, are important components of transportation networks. They guide, warn, and protect drivers and regulate traffic. To manage and maintain the regular operation of the highway system, state departments of transportation... Over the last two decades, the use of advanced scientific and data-driven statistical methods has been continuously evolving to reduce the frequency and severity of crashes on our roadways. The American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual (HSM) was... |
