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...

Unsignalized intersection cooperation of connected and automated vehicles (CAVs) is able to eliminate green time loss signalized intersections improve traffic efficiency. Most the existing research on unsignalized considers fixed lane direction, where only specific turning behavior allowed each lane. Given that volume proportion with different expectation may change time, direction lead ineffic...

In this paper, we present a new multi camera approach to Lane Departure Warning (LDW). First, a perspective removal transformation is applied to the camera captured images to convert them into bird’s-eye view images. Then, the position of the two cameras relative to a reference point is accurately determined using a new calibration technique. Lane detection is performed on the front and rear ca...

The animals were subjected to hormone treatment for 1 week. Hormones were administered either continuously via osmotic minipumps (m.p.) or intermittently by subcutaneous injections once ( 1 x s.c.) or twice (2 x s.c.) daily. Daily doses were 120 pg for GH and 100 pg for methyltrienolone, respectively. Lane I , control female; lane 2, hypophysectomized (Hx) female; lane 3, female + androgen (met...

Road lane detection and tracking methods are the state of the art in present driver assistance systems. However, lane detection methods that exploit the parallel processing capabilities of heterogeneous high performance computing devices such as FPGAs (or GPUs), a technology that potentially will replace ECUs in a coming generation of cars, are a rare subject of interest. In this thesis a road ...
