When the Traffic Engineering Division receives a request to do an engineering study of a particular intersection, a series of steps can take place.

  1. Traffic crews conduct an engineering study to see if the location meets "warrants" which means meeting the minimum legal criteria as is required by the Manual on Uniform Traffic Control Devices (MUTCD). This engineering study is an information gathering process. Information is collected regarding traffic volume, the speed that traffic is flowing, the amount of pedestrian activity, accident history and the distance the proposed new signal location is away from adjacent signals.
  2. If the location passes the engineering study, the new traffic signal site goes on a priority list and the ranking on the list is determined by the traffic volume figures and accident history.
  3. Each year, based on funding, the city of Las Vegas starts at the top of the priority list with the goal of constructing as many new signals as the budget will allow.
  4. Once funding is available, a traffic signal design is prepared. As part of the design, bid specifications are also prepared. This process takes between two and three months.
  5. The signal project then goes out to bid, which takes between two and three months.
  6. The project is awarded and construction begins and takes approximately six months to complete.
  7. Traffic crews turn on the signal at the new location.
