     Traffic Management Plan – 25040286

               An estimated end-of-queue position is to be determined for the approach to each traffic control station
               and is to be based on the maximum expected traffic flow on that approach during the time traffic control
               will be in operation.
               The count or estimate of the number of average and heavy vehicles during a five-minute period at a
               site may be completed using the following in order of preference:

                         1. Actual five-minute count of vehicles during the peak time the site will be occupied. This five-minute
                         count is based on the vehicles approaching the selected traffic control station from the approach to be
                         controlled by that station (not a sum of both directions of traffic). Consideration of peak traffic flow
                         direction may be needed.

                         2. If a five-minute count is not possible, use annual average daily traffic (AADT) values with hourly
                         breakdowns and percentage heavy vehicle data. To estimate the five-minute count, select the peak
                         hourly period during the time the site will be occupied and divide by 12 to get an estimated five-minute
                         value. Divide this by two if the AADT is for a two-way road. Use the percentage heavy vehicles
                         information with this value to estimate the number of heavy vehicles for this five-minute period.

                         3. If a five-minute count is not possible, and AADT values with hourly breakdowns are not available, use
                         AADT values and percentage heavy vehicle data. To estimate the five-minute count, firstly divide the
                         AADT by a factor of 10 (to get an estimated hourly count) and then divide this by 12 to get an estimated
                         five-minute value. Divide this by two if the AADT is for a two-way road. Use the percentage heavy
                         vehicles information with this value to estimate the number of heavy vehicles for this five-minute period.
                         AADT information for state-controlled roads can be located on the Queensland Open Data Portal – Traffic
                         Census data.


               A marker (for example, a cone or bollard) should be placed on the shoulder at the predicted end-of-
               queue to assist the traffic controller and traffic management implementer to monitor queue lengths.

               When estimating the queue length, Table 4.3 uses an average vehicle length of 6 m and an average
               heavy vehicle length of 20 m for a five-minute stopping time (based on the five-minute traffic count) and
               then adjusts the multipliers for other stopping time values.
               Where very long vehicles are expected (for example outback and mining routes or routes where most
               vehicles are towing), then to ensure estimated queue lengths are as accurate as possible, use an
               average length per vehicle that matches the actual traffic mix expected at that location.

          5.1.7     End of queue protection

     No Additional End of queue protection required due to low speed road.


          5.1.8     Use of hazard lights by last vehicle in queue

     The use of hazard lights by the last vehicle is not required with this project.

          5.1.9     Use of enhanced queued traffic warning signs (TM1-46-Q01)

     The use if enhanced queued traffic warning signs is not required for this project.

          5.1.10 Temporary Traffic Signals

     Temporary traffic signals are not required with this project.

          5.2 Speed Management Plan

     A speed management plan is not required with this project.
