Orange Work Zone Pavement Marking Midwest Field Test

During construction on freeways and other multi-lane high-speed roadways it is frequently necessary to adjust the lateral position of driving lanes. Incomplete removal of old pavement markings and scarring of the surface where old markings have been removed can create ambiguity for drivers. The uncertainty associated with "ghost' or "phantom" markings is particularly acute when lane positions have been moved more than once, especially on facilities that have three or more lanes open to traffic. It can be exacerbated by lighting (e.g. low solar angles), wet pavement, and other adverse conditions. Winter work zones present a particular concern to Midwestern practitioners because salt residue reduces contrast between the "proper" temporary markings and the rest of the pavement surface. Consequently, Midwestern departments of transportation (DOTs) have sometimes found it necessary to mill and overlay the pavement to create a uniform surface-a costly solution to what is typically a temporary problem. A number of international highway agencies address this issue through a less expensive alternative: fluorescent orange pavement markings. This technique has been widely used in Ontario (Canada] and is being made standard for all freeway work zones in Switzerland. The technique has also been used in New Zealand, Germany, and other countries. The goal of this project is to gauge agency, contractor, and public satisfaction with experimental orange work zone pavement markings to be installed by one or more collaborating Midwestern DOTs. The researchers will also conduct direct observation of traffic to attempt to assess whether the orange markings reduce erratic driver behaviors (such as harsh braking and abrupt lane changes) that can be considered crash precursors.
