Evaluating and Forecasting the Operational Performance of Road Intersections
Road intersections represent one of the most complex configurations encountered when traversing road networks. It is therefore of vital importance to improve their operational performance, as that can significantly contribute towards the efficiency of the whole transport network. Traditional …

Safety verification and control for collision avoidance at road intersections
… we design centralized coordinators at road intersections, called supervisors, that monitor the dynamical state of vehicles and the current input of drivers and override them if necessary to prevent a collision. The primary technical problem in the design of such systems is to determine …

Safety Effects Of Traffic Signal Installations On State Road Intersections In Northeast Florida
… of traffic signals affect crash experience at intersections, to identify those factors which help predict crashes after a signal is installed, and to develop a crash prediction model. It is the intent of this thesis to supplement the Manual on Uniform Traffic Control Devices Signal Warrant …

Self Synchronization of Moving Vehicles
… scheme for conflict-free movement of vehicles at road intersections. We claim that our scheduling scheme not only guarantees conflict-free movement at any intersection, it also provides nonstop movement for the maximum possible number of vehicles at multiple intersections on its route. If it is …

MapLite : autonomous navigation in rural environments without detailed prior maps
… The onboard sensors are used to segment the road region and register the topometric map in order to fuse the high-level navigation goals with a variational path planner in the vehicle frame. This enables the system to plan trajectories that correctly navigate road intersections without the …

Cooperative Decentralized Intersection Collision Avoidance Using Extended Kalman Filtering
… substantial portion of these accidents occur at road intersections. Stop signs and traffic signals are some of the intersection control devices used to increase safety and prevent collisions. However, these devices themselves can contribute to collisions, are costly, inefficient, and are prone to …

Road-based proactive routing protocols for vehicular networks
… the UbiNetS lab at NJIT has proposed the idea of Road-Based using Vehicular Traffic information (RBVT) routing. In RBVT, routes are sequences of road intersections, and geographical forwarding is used for sending packets between the intersections. This thesis proposes two proactive RBVT protocols …

Road-based routing in vehicular ad hoc networks
… three forwarding optimizations for VANETs. The Road-Based using Vehicular Traffic (RBVT) routing is a novel class of routing protocols for VANETs. RBVT protocols leverage real-time vehicular traffic information to create stable road-based paths consisting of successions of road intersections …

Low-Cost Dual Radar System for Collision Prediction at Unregulated Intersections
… shift in the automotive market towards reducing road accidents has led to the development of many sensor-based collision avoidance systems. The majority of such systems are limited to high-end vehicles. Statistics indicate road intersections are a common location for car accidents. In South …

Spatial Analysis of Fatal Automobile Crashes in Nashville, TN, 2001-2011
… accidents happen is critical in order to ensure road safety and to plan for adequate road infrastructure. There is a rich body of literature pertaining to time-related fatal crashes, most of which focuses on non-spatial factors such as a driver’s visibility at night, drinking and drug use, and …

Preparing in Libraries: Educational Change, Joblessness, and Youth Practice in North India
… in formal colleges or university spaces or busy road intersections, a significant section of unemployed young people with whom I worked spent considerable time within such private, commodified study-spaces. The practices of preparation within libraries are meant to actively counter young people’s …

EVALUATION AND MITIGATION OF THE RISK OF ROAD ACCIDENT IN URBAN AREAS ACCORDING TO TECHNIQUES BASED ON HUMAN-ROAD INTERACTION
Deaths and injuries resulting from road traffic crashes is a serious problem globally and current trends suggest that this will continue to be the case in the foreseeable future. The number of road traffic deaths continues to climb, reaching a high of 1.35 million in 2016. That’s nearly 3 700 …

Bicycle detection through the use of inductance loop detectors at vehicular actuated traffic signals
… involves bicyclists that attempt to pass through intersections controlled by vehicular actuated traffic signals. The proper operation of a vehicular actuated traffic signal depends on in-road sensing devices that detect vehicle presence and/or passage. Proper detector operation is, however, …
