Deceleration lanes are important because they help drivers transition from high-speed lanes to low-speed ramps. Although they are designed to allow vehicles to depart the freeway safely and efficiently, many studies report high accident rates on exit ramps with the highest percentage of crashes taking place in deceleration lanes. This paper describes the results of a driving simulator study tha...

The objective of the current study was to assess the separate and combined effects of marijuana and alcohol on actual driving performance. Eighteen subjects were treated with drugs and placebo according to a balanced, 6-way, crossover design. On separate evenings they were given weight calibrated Delta(9)-tetrahydrocannabinol (THC) doses of 0, 100 and 200 &mgr;g/kg with and without an alcohol d...

image analysis is an image processing technique that aims to extract features or information from images. image analysis in medicine has a special place because is a basis for disease diagnosis for physicians. electrophoresis is a laboratory separating technique. electrophoresis images are created during the electrophoresis process. serum protein and hemoglobin electrophoresis test are the most...

Research has shown that road lane width impacts on driver behaviour. This literature review provides guidelines to assist in the design, construction and retrofitting of urban roads to accommodate road users' safety requirements. It focuses on the impacts of lane widths on cyclists and motor vehicle safety behaviour. The literature review commenced with a search of library databases. Peer revie...

OBJECTIVE To evaluate the rate of deviation in the lateral radiographic incidence in patients with femoral neck fracture classified as non-diverted in the anteroposterior view (Garden I and II). METHODS Nineteen selected patients with femoral neck fractures classified as Garden I and II were retrospectively evaluated, estimating the degree of deviation in the lateral view. RESULTS Fifteen c...

The provision of lane-level travel time information can enable accurate traffic control and route guidance in urban roads with distinctive conditions among lanes. However, few studies the literature have been conducted to estimate distributions. This study proposes a new vehicle re-identification (V-ReID) method for estimating distributions using video images from widely deployed surveillance c...

Recent investigations on the longitudinal and lateral control of wheeled autonomous vehicles are reported. Flatness-based techniques are first introduced via a simplified model. It depends on some physical parameters, like cornering stiffness coefficients of the tires, friction coefficient of the road, . . . , which are notoriously difficult to identify. Then a model-free control strategy, whic...

Road departure is one of the main causes single vehicle and frontal crashes. By implementing lateral support systems, a significant amount these accidents can be avoided. Typical are normally occurring due to unintentional lane where driver drifts towards across line identifying edge lane. The Lane Support Systems (LSS) uses cameras “read” lines on road alert if car approaching lines. Anyway, d...

Freeways form an important part of the road network. Drivers’ behavior can be split in longitudinal (acceleration and deceleration) and lateral behavior (lane changing). The combination of these two behaviors on freeways play a key role in traffic operations. This paper tries to describe the driving behavior, emphasizing the relation between the lateral and longitudinal behavior. To this end, a...
