A system for monitoring traffic flow on multi-laned roadways. The system includes a plurality of radiation sources such as light emitting diodes, LEDs and a corresponding set of radiation detectors such as photo diodes. The radiation sources and detectors form a crossed array as well as direct ...
Although there have been several different approaches to the problem, recent work has centered on a method based on five descriptive factors: per-lane traffic volume, speed of traffic, right-hand-lane width (including the width of bicycle lanes or road shoulders), overall pavement quality, and ...

Unfortunately, two major roads involved in the project were going to be hazardous for bicyclists. Both roads included double-lane automobile right-turns that would cross bike-traffic space. The roadways also approached two of the four bike-accessible bridges in Portland, where bridge access is ...
These observations led to multivariate regression models of the lateral position of motorists and cyclists based on geometric and traffic characteristics such as motor vehicle lane width, percentage of truck traffic, presence and 展开 被引量: 5 年份: 2006 ...
Guidelines for the use of right-turn lanes at access points on urban two-lane and four-lane roadways were developed. The guidelines define the design-hour traffic volumes for which the benefits of right-turn lanes exceed their costs. The benefits used in the analysis were the operational and ...

Installed permanently or temporarily upstream of motorists' decision points, CMS is used to communicate real time traffic information to motorists so that motorists can make better informed travel decisions. For example, downstream collision information may cause the informed motorists to detour to other...
