Rumble strips are roadway safety features built into or applied over the road in order to create a vibration and sound to alert an inattentive driver that they are departing the lane.

This dataset contains lines representing the rumble strips located on interstates, ramps, state routes, and locally owned NHS routes in Tennessee. This dataset can be queried by location information. These records were derived from vehicle mounted LiDAR sensors and digitally captured photos. This information was collected by Mandli Communications, Inc. under the direction of the Asset Management Division and the Long Range Planning Division. Questions on this dataset should be directed to TDOT.Maint.AssetManagement@tn.gov.

The South Jersey Transportation Planning Organization (SJTPO) is the Metropolitan Planning Organization (MPO) covering Atlantic, Cape May, Cumberland, and Salem Counties in southern New Jersey. Formed in 1993, SJTPO serves as a technical resource, provides access to funding, and works to provide a regional approach to address transportation planning and engineering issues. As part of SJTPO's Countywide Local Road Safety Plan Effort, an extensive data collection effort was undergone. The geometry for this layer was created by reviewing all roads within the NJDOT Roadway Network File (RNF) that reside within the SJTPO region. Segments under county jurisdiction were included. Google Street View was used to determine if a rumble strip was present. A line was then drawn over the length of the strip using the latest aerial imagery available (NJGIN Natural Color 2020 WMS Aerial Imagery or Google Maps. The data collection began in October 2023 and was completed by December 2023.More information of the data collection effort can be found here.

This initiative includes a variety of low-cost measures that are effective in reducing roadway departure crashes. Eligible treatments include signs, pavement markings, and transverse rumble strips warning drivers of upcoming curves; enhanced delineation of the roadway and topography through regular width or wide centerline and/or edgeline pavement markings and retroreflective elements (such strips attached to sign posts, markers on guardrails, or ground-mounted delineators along the edge of the roadway); warnings for drivers who may be leaving the travel lane through centerline and/or edgeline rumble strips/stripes; and removing roadside hazards through selective tree removal. The list is identified by the VTRC Report 21-R10 and the detail information is found on implementaion criteira.

Driver error is estimated to cause about half of all traffic accidents in Arizona and the United States. To understand driver error and related remedies, this reference document provides results from a literature review, a survey of state agencies, and a number of case studies to identify innovative and effective remedies for driver error as well as factors affecting their success. The literature review outlines the different types of driver error and contributing factors as well as the effects of risk homeostasis and motivation. The literature review also provides information on a range of education, enforcement, and engineering measures used to reduce the frequency of these errors and address the perceived costs or risks associated with different driver behaviors. A survey of state practices highlights effective strategies such as targeted campaigns integrating education and enforcement, as well as low cost, preventative engineering solutions such as rumble strips and improved signage and pavement markings. More detailed descriptions of strategies are also provided in five best practice case studies from around the United States. Literature, survey, and case study information provide a number of lessons regarding the features of a successful program of remedies for driver error.
