Daniel L. Carter, P.E.

Senior Engineering Research Associate

Daniel Carter is a senior engineering research associate with the Highway Safety Research Center where he handles data collection and analysis for many types of highway safety studies. His areas of experience include safety treatment evaluation (specifically low cost countermeasures), GIS data management, pedestrian and bicycle safety, blind and visually impaired pedestrian safety, large truck safety, and access management strategies.

Current and past projects include:

  • Evaluation of Low Cost Safety Strategies (FHWA). The objective of this project is to conduct a crash-based evaluation of low cost safety treatments through a statistically sound before-after approach. Such treatments include two-way left turn lanes, flashing beacons and horizontal curve delineation.
  • Model Minimum Inventory of Roadway Elements (FHWA). The objective of this project was to develop a Model Minimum Inventory of Roadway Elements (MMIRE) that will expand highway agencies' roadway element and traffic flow inventories, but also encourage the standardization of data collection across the country.
  • Crash Modification Factors Clearinghouse (FHWA). This project undertook the development of a clearinghouse of information on crash modification factors to be easily searched and accessed by practitioners seeking to quantify the effects of potential countermeasures. This Clearinghouse compiled CMF information from the Highway Safety Manual and FHWA Desktop Reference Guide and is regularly updated with new research on CMFs.
  • Guidelines for Accessible Pedestrian Signals (NCHRP 3-62). The objective of this project was to evaluate various configurations of accessible pedestrian signals and determine the effectiveness of assisting the visually impaired population in making street crossings. The results have been used to recommend changes in MUTCD guidance and to develop workshops for practitioners on the installation, operation and maintenance of these devices.
  • Pedestrian and Bicycle Intersection Safety Indices (FHWA). The objective of this project was to match crosswalk or intersection approach leg characteristics with safety measures, the result of which was a safety index tool that would evaluate a crosswalk or approach with respect to pedestrian or bicyclist safety. The result was an easy-to-use tool that prioritizes these sites so that local practitioners could focus available resources on improving safety at intersections that need it most.

Mr. Carter is licensed as a Professional Engineer in North Carolina. He currently serves as a member of the TRB Committee on Operational Effects of Geometrics.

His previous experience includes his time as a graduate student researcher at North Carolina State University, where he collected and analyzed operational and safety data on U-turns at signalized intersections. Mr. Carter earned both his bachelor's and master's degrees at North Carolina State.

Outside of work, he enjoys singing, stringed instruments and foreign languages, specifically French and Romanian. He and his wife Alexa have three kids and live in Durham.
