This paper proposes Multi-stream Minimum Acceptable Space (MMAS) Cellular Automata (CA) models to study unsignalised multi-lane (twoor three-lane) urban roundabouts. Through detailed space considerations, using Cellular Automata (CA) and the Multi-stream Minimum Acceptable Space method, heterogeneity and inconsistency of driver behavior and interactions in cross traffic at entrances of roundabo...

One of the main goals in developing an autonomous vehicle is programming the action of merging into the traffic lane from an entrance ramp. We seek to create such a behavior through the use of NeuroEvolution of Augmenting Topologies (NEAT) by evolving an agent over many generations to maximize a certain prescribed fitness function, which encourages a smooth merging behavior without crashing. Ou...

Applications of camera vision, such as lane departure warning systems, are limited by the quality of the frame image and the information contained within each frame. One common feature extraction technique in image processing is the use of the Hough transform, which can be used to extract lines from an image. The detected lane marking lines are used in the interpolation of a 2 nd order polynomi...

Signal timing and lane allocation are most important settings at signalized intersections to control the operation. Efficiently operated traffic signals and reasonably designed lane markings can reduce congestion and bring about significant payoffs in time and energy benefits. The design of signal timing plan and lane allocation pattern should be complementary to each other; however, existing r...

An integral component of Autonomous Driver Assistance system is the robust detection and tracking of lane markings. It is a rigid problem due to large appearance variations in lane markings caused by factors such as improper illumination (transition from day to night), occlusion (traffic on the road), shadows from objects, etc. In this paper, we present a robust partition based lane detection a...

SimTraffic and VISSIM are two microscopic traffic simulation tools that are capable of modeling arterial roads with signalized intersections and roundabouts. This study compares the performance of the two simulation tools in modeling dual lane and triple lane roundabouts under different scenarios such as traffic volume, proportion of left turning movement, and proportion of trucks in the traffi...
