Background and Objective: This study aims to improve the capacity level of service at sixth circle in Jordan by using traffic signals a roundabout metering approach. Methods: VISSIM software C++ program were used service. The site area (Sixth circle) was located near Crown Plaza Gate Towers project, which causes congestion due heavy flow. Therefore, this paper assesses presents possible solutio...

The concept of Ford’s lane keeping sys­ tem includes two variants: The driver can select a warning function and a lane keeping function in case the vehicle leaves its current lane, known as lane keeping alert, ❶, and lane keeping aid, ❷, respectively. Both functions make use of a camera serving as a sensor for iden­ tifying the traffic lane and the lane mark­ ings. Identifying the ve hicle’s ow...

This study tested the effects of lane width, lane position and edge shoulder width on driving behavior for a three-lane underground urban expressway. A driving simulator was used with 24 volunteer test subjects. Five lane widths (2.85, 3.00, 3.25, 3.50, and 3.75 m) and three shoulder widths (0.50, 0.75, and 1.00 m) were studied. Driving speed, lane deviation and subjective perception of driving...

Tail-recursive function definitions are sometimes more straightforward than alternatives, but proving theorems on them may be roundabout because of the peculiar form of the resulting recursion induction rules. This paper describes a proof method that provides a general solution to this problem by means of suitable invariants over inductive sets, and illustrates the application of such method by...

This paper analyzes the interdependency between the dynamics of queues at isolated signalized intersections and the lane-changing behavior of vehicles approaching the intersection. A dynamic queuing model based on Markov Chain renewal process is combined with a lane-changing behavior model in order to simulate the vehicle distribution in time. We applied this simulation to a two-lane intersecti...

Access to relative location of nearby vehicles on the local roads or on the freeways is useful for providing critical alerts to the drivers, thereby enhancing their driving experience as well as reducing the chances of accidents. The problem of determining the relative location of two vehicles can be broken into two smaller subproblems: (i) Relative lane localization, where a vehicle determines...
