Filter by Keyword158 report(s) found with safety in the keywords field Train-pedestrian conflicts result in a substantial number of serious and fatal injuries annually. Signs indicating safe and permissible behaviors near railroad rights-of-way are commonly relied upon to mitigate collisions. However, the effectiveness of these signs in preventing accidents depends on the... Winter storms significantly increase crash risk and disrupt travel, especially under extreme conditions. Gusty winds, heavy moisture, and low temperatures can quickly make travel dangerous in the Northern Plains. This study was aimed at understanding winter truck crashes, given the prominence of commercial... Public education and outreach activities increase the effectiveness of work law enforcement does to prevent large truck-involved crashes. This demonstration project was conducted through two components including a primary education program and a complimentary education program designed to be executed... This research project’s objective was to investigate the impacts of transit stop location (near-side versus far-side) on pedestrian safety and traffic operations at intersections. Three different video-based behavioral observation data collections at signals in Utah were utilized and studied: (1) transit... An efficient and safe transportation system is essential to communities during the long-term recovery period after earthquakes. A disrupted transportation network due to infrastructure damage or failure affects the functionality of the traffic system and poses increased traffic safety risks. A rational... Transportation planning, traffic monitoring, and traffic safety analysis require detailed information about pedestrian volumes, but such data are usually lacking. Fortunately, recent research has demonstrated the accuracy of pedestrian volumes estimated from push-button data contained within high-resolution... A community is considered walkable if it is easy and safe for pedestrians to walk for recreation and exercise and to destinations such as schools, stores, parks, and post offices. A walkable community encourages the safe use of existing infrastructure while expanding transportation options for users... Construction projects require long hours where workers are subjected to intensive tasks such as hard manual labor, heavy lifting, and constrained working postures. Among the physiological metrics, heart rate (HR) is reported to be a good indicator of physical stress and workload. HR forecasting models... As roundabouts become increasingly popular, and as many communities promote bicycle use, the safety of roundabouts for people bicycling is of major concern. In this project, we studied bicyclists' safety perceptions of and preferences for roundabouts with different characteristics. First, we performed... Roadside safety is a critical aspect of transportation management, with elements like rigid obstacles, guardrails, clear zones, and side slopes significantly impacting accident outcomes. The Federal Highway Administration (FHWA) provides a valuable rating system for departments of transportation (DOTs)... |
