Clark County Public Works regularly receives inquiries from the public and the County Commission about the possibility of installing new traffic signals or multi-way stop signs at certain intersections where these devices do not currently exist.

The Traffic Management Division staff, or a private engineering consultant under contract with the county, evaluates existing traffic volumes and the crash history at each selected intersection to determine if a traffic signal or other change of traffic control device is warranted.

Nevada Revised Statutes 484.781 states that all traffic control devices used by local authorities must conform to the manual and specifications adopted by the Nevada Department of Transportation (NDOT). NDOT has adopted the Manual on Uniform Traffic Control Devices (MUTCD). The MUTCD requires that an intersection satisfy at least one of the eight traffic signal warrants before a signal can be legally installed.

The warrants are tests against the intersection’s current vehicular and pedestrian volumes and an analysis of its crash history. Please note that case law has consistently held that satisfaction of one or more warrants does not mandate a signal installation at an intersection.

The actual data collection and analysis typically take only about two weeks. Due to the high volume of requests; however, there is always a backlog of warrant studies. The average study takes about two months from the request to its completion.

Currently, Public Works Traffic Management is getting assistance from consultants to reduce the backlog. If the traffic signal warrant study concludes that a traffic signal is warranted, then a process to design, fund, and construct the signal is initiated.

The following webpage link provides the status of intersections that were either recently studied or are to be studied in the near future http://www.accessclarkcounty.com/pubworks/construction/traffic/Studies_Master.pdf
