Filter by Keyword204 report(s) found with analysis in the keywords field The ultimate objective of this project was to determine the structural performance of the dynamic message sign (DMS) bonded with chemical adhesive in terms of ultimate strength and fatigue strength. To achieve this objective, this project first investigated the effects of various parameters (i.e., conditioning... Academic literature has scant research on sidewalks, and some cities are lacking information to rectify an unprecedented backlog of deteriorating pedestrian infrastructure. A lack of data stymies efforts to understand sidewalks, how they may impact equity, and how cities can prioritize where to begin... The number of Americans age 65 and older is projected to nearly double from 52 million in 2018 to 95 million by 2060, and the 65-and-older age group's share of the total population will rise from 16% to 23% (US Census 2018). Also, average U.S. life expectancy increased from 68 years in 1950 to 78.6 years... Local governments have an immediate need for low life-cycle cost bridge replacement alternatives. Knowledge of available alternatives and construction planning processes hold potential for South Dakota local governments to replace more structurally deficient local bridges with limited funds. Through... Over a century of research suggests that the size and spatial location of various streetscape features impacts outcomes such as walkability, livability, and road safety. Current streetscape feature measuring/mapping techniques are limited to subjective audit-based methods, crude feature counts, or simple... Traffic volume data are crucial in many applications, including transportation operation analysis, congestion management, and accident prevention. Yet an extensive capture of accurate volume information on a large-scale network can be difficult and costly. This research focuses on hourly traffic volume... Snowplow trucks serve a crucial role in winter maintenance activities by removing, loading, and disposing of snow. An effective performance monitoring and analysis process can assist transportation agencies in effectively managing the snowplow trucks and maintaining normal functioning of roadways. Previous... Bicycle and scooter use entails significant safety and health risks. News stories have described the reckless behavior of users across the United States with the emergence of micromobility options. This paper investigates risky behaviors associated with U.S. bicycle and scooter riding adults. Two separate... Achieving and maintaining public transportation rolling stocks in a state of good repair is very crucial to providing safe and reliable services to riders. Transit agencies that seek federal grants must also keep their transit assets in a state of good repair. Therefore, transit agencies in small urban... Despite similarities to the US in terms of transportation, land use, and culture, Australia kills 5.3 people per 100,000 population on the roads each year, as compared to the US rate of 12.4. Similar trends hold when accounting for distance driven and the number of registered cars. This paper seeks to... |
