Many rural roadways in Iowa have centerline and/or edgeline pavement markings. The current Manual on Uniform Traffic Control Devices (MUTCD), however, requires centerline and/or edgeline pavement markings only along streets and roadways with traffic volumes much greater than 400 vehicles per day (the volume-based definition of a low-volume roadway in the MUTCD). This project was initiated to ga...

When drivers are approaching a signalized intersection at the onset of a yellow change interval, they must decide whether to stop or cross the intersection. This can be a difficult decision when the vehicle is located within the dilemma zone and the result is sometimes a rear-end crash due to a sudden stop. This paper presented a new pavement-marking countermeasure which purpose is to reduce th...

Researchers performed a before-and-after analysis of speeds to determine the short-term and long-term effectiveness of an experimental transverse-bar pavement marking treatment at the “Plainfield Curve” on I-43/94 in Milwaukee, Wisconsin. The experimental transverse pavement marking treatment was installed in both the northbound and southbound lanes in early September 2006 and each treatment se...

This paper provides an overview of recent advancements in road signage, vehicle visibility and pavement marking technology developed by 3M and how they can be applied to improve safer navigation on the road, especially for large vehicles and compromised situations.

Kinzel 2 Fig 1. " Standard " two-lane roundabout and key terms Abstract. Multi-lane roundabouts present motorists with a complex set of decisions. Unlike single-lane roundabouts, for which the only rule on entry is " yield to the driver on your left, then circulate to your right " , multi-lane roundabouts also require decisions about lane positioning – and these decisions are necessary at multi...

Most vision-based system for lane detection and tracking use painted lane markings as the visual cues which determine the location of the camera relative to the lane. Almost all of the work that has been done in the area of evaluating the pegformance of these systems has focused on the accuracy of the recovered lane geometry. Reliability of feature detection as a function of intrinsic marking p...
