Parameters for Setting Speed Limits |
Speed Limit Task Force of the NCUTCD
The National Committee on Uniform Traffic Control Devices (NCUTCD) task force on speed limits is reviewing the language in the MUTCD related to setting speed limits. This task force review is in response to findings from the recent National Transportation Safety Board (NTSB) report on speed limits. In this report the NTSB called for FHWA to consider four recommendations (page 57); two of the findings related to the MUTCD (see below, the other two were related to automated enforcement). This NCUTCD task force wants your input on the NTSB findings before advancing recommendations through technical committees of the NCUTCD Council for future FHWA updates to the MUTCD. This 13 question survey is technical in nature related to speed limits and should take about five minutes to complete. The findings will be utilized by the task force and shared with the profession following completion. The objective will be to have a recommendation to present to the NCUTCD technical committees in 2018. Thank you for your interest and participation. Please share this survey with others in your organization if you feel that they would be interested or may better be able to question related to setting speed limits.
The two MUTCD related recommendations from NTSB to FHWA included:
#1 (H-17-27): Revise Section 2B.13 of the Manual on Uniform Traffic Control Devices so that the factors currently listed as optional for all engineering studies are required, require that an expert system such as USLIMITS2 be used as a validation tool, and remove the guidance that speed limits in speed zones should be within 5 mph of the 85th percentile speed.
#2 (H-17-28): Revise Section 2B.13 of the Manual on Uniform Traffic Control Devices to, at a minimum, incorporate the safe system approach for urban roads to strengthen protection for vulnerable road users.
#2 (H-17-28): Revise Section 2B.13 of the Manual on Uniform Traffic Control Devices to, at a minimum, incorporate the safe system approach for urban roads to strengthen protection for vulnerable road users.
