Traffic control devices applied to the pavement can provide a significant amount of information for the driver. The objective of this research was to assess the effectiveness of various pavement marking materials, devices, and treatments that have potential to increase driver awareness and safety. The following pavement marking materials, devices, and treatments were investigated as part of this research project: . yellow-green crosswalk material, . in-roadway warning lights, . fluorescent orange retroreflective raised pavement markers, . "removable" pavement marking paint, and . rumble strips. This report includes recommendations for the application of in-roadway warning lights and rumble strips. Further research is needed on the yellow-green crosswalk material, fluorescent orange retroreflective raised pavement markers, and the "removable" pavement marking paint before application guidelines can be developed.

Paved shoulders can help accommodate non-motorized vehicles, allow errant vehicles to recover, and effectively reduce crash numbers.

TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.

"These 24 papers examine various topics related to pedestrians, bicycles, and motorcycles. Specific topics discussed include the following: counting pedestrians at intersections; estimating pedestrian intersection crossing volumes; automatic pedestrian detection device and smart lighting; impact of weather and season on pedestrian traffic volumes; automated analysis of pedestrian–vehicle conflicts using video data; FHWA project to reduce pedestrian fatalities, injuries and conflicts; pedestrian crosswalks at midblock locations; pedestrian scramble operations; LED rectangular rapid-flash beacons for yielding to pedestrians in multilane crosswalks; work zone accommodation of visually impaired pedestrians; performance measures for visually impaired pedestrian crosswalks; comparing latent walk trips in Toronto and Montreal; pedestrian safety education for elementary and middle school children; walking behavior analysis; relaxed pedestrian behavior; pedestrian and bicyclist exposure to risk; modeling bicycle facility operation; influences on the decision to bike; bicycle helmet wearing among adolescents; risk taking in moped and motorcycle crashes; impaired motorcycle operation; modeling urban traffic containing motorcycles; effectiveness of motorcycle training and licensing; and safety effectiveness of HAWK pedestrian treatment."--pub. desc.
