Using Real-Time Data from Roadway Weather Information Systems to Affect Driver Behavior During Inclement Weather

The objective of this project is to determine the feasibility of using the existing road weather information system (RWIS) data in conjunction with a variable speed limit (VSL) system to influence motorist behavior with the goal of reducing crashes on Interstate 40 in New Mexico.

During inclement weather, there are numerous vehicle crashes that occur on Interstate 40 (I-40) in New Mexico near the Continental Divide at the "Top of the World"  (mm 50). A major contributing factor in the vicinity of the "Top of the World"  as identified by NMDOT based on crash report information is the failure of drivers to reduce their speed to a level at which they can maintain control of their vehicle. The objective of this project is to determine the feasibility of using the existing road weather information system (RWIS) data in conjunction with a variable speed limit (VSL) system to influence motorist behavior with the goal of reducing crashes in the vicinity. To accomplish this a literature search, interviews of other state department of transportation (DOT) personnel and local transportation agencies and a survey of New Mexico DOT personnel will be conducted.
