A model-based dynamic toll pricing strategy for controlling highway traffic
… A novel approach is suggested for alleviating traffic congestion, which utilizes identified models of driver behavior and traffic flow, as well as optimization of the target density to maximize throughput. Real-time traffic information from on-road sensors is integrated with historical …

Semi-autonomous driving control of multi-trailer articulated heavy vehicles for increasing highway traffic safety
… Articulated Heavy Vehicles (MTAHVs) to enhance highway safety and transportation efficiency. While autonomous driving has progressed, concerns about safety, reliability, and ethical issues remain, making the transition to full autonomy gradual. Unlike the extensive focus on semi-autonomous …

Evaluating Public Sector Employee Performance: Police Productivity as a Case Study (goal-Setting, Law Enforcement, Highway Traffic Safety)
Public demands and budget constraints have brought new attention to the issue of improving public sector employee performance; especially in essential public services. Public agencies have traditionally sought to improve performance through job restructuring, reduced manpower, and the adoption of …

Assessing the Effects of the Ignition-Interlock Device on Recidivism
In 2012, there were 10,322 traffic fatalities in the U.S. involving at least one driver with a blood-alcohol concentration (BAC) of .08 or higher. This was approximately 31% of all traffic fatalities that year (National Highway Traffic Safety Administration, 2013a). The ignition-interlock device is …

Exploring entities in text with descriptive non-photorealistic rendering
… of vehicle complaint reports from National Highway Traffic Safety Administration (NHTSA), and through a qualitative evaluation study, we demonstrate how our system can support tasks such as comparing the reliability of di fferent makes and models, finding interesting facts, and revealing …

Designing an Emergency Traffic Signal System (ETSS): A Case Study of an Intersection Along U.S.1, Fairfax County, Virginia
Access to highways from a local firehouse is a major problem for emergency services. Motorists often do not see flashing lights or hear sirens from the approaching emergency vehicles (EV) until emergency vehicles reach the highway entrance, often too late to take appropriate action. Many locations …

Assessing the relationship between recurring and nonrecurring traffic congestion
… and diffusion limited aggregation to describe highway traffic flow. The formulation is platoon based and is most applicable for describing uninterrupted-flow facilities. The model explains empirical models in terms of fractal dimensions. The concepts of change in length of a platoon and a …

An acoustical based approach to conceptual design of non-traditional rotorcraft configurations
As interstate and highway traffic increases, commute times become drastically large. Such large commute times create fatigue and take away from productive hours at work, or joyful hours at home. The idea of urban air mobility becomes increasingly more attractive and viable as technology improves. …

Simulation and queueing network model formulation of mixed automated and non-automated traffic in urban settings
… autonomous vehicles offer numerous benefits to highway traffic, but their impact on traffic in urban scenarios with mixed autonomous and non-autonomous traffic is less understood. This research addresses this issue by using microscopic traffic simulation to develop understanding of how traffic …

Assessing the Performance of an Emergency Vehicle Preemption System: A Case Study on U.S. 1 in Fairfax County, Virginia
Highway traffic control systems have been deployed to provide emergency vehicle preemption (EVP) at signalized intersections. Industry and transportation researchers have worked to develop analytical methods to establish the degree of benefit of emergency vehicle preemption to the emergency vehicle …

An approach to predict traffic congestion
… a relationship between speed and density of the traffic stream. The input to this model is obtained from a presence type detector system. These measurements are then used to calculate various parameters and then the state of the traffic flow for the vehicular stream in the test zone is …

An observational study of freeway lane-changing behaviour
… lane-changing is a very important component in highway traffic flow. In this study, a mathematical model to describe the lane-changing behaviour is suggested based on the lane-changing hypothesis that whenever there is a lane-changing maneuver, the average speed of the neighboring lane is faster …
