 The previous simulation shows the current situation in Wool. The next stage is to show how the extra 1000 homes will affect the traffic flows.  The previous simulation shows the current situation in Wool. The next stage is to show how the extra 1000 homes will affect the traffic flows. 
  
-The extra traffic was calculated on a previous page [[woolcrossingtrafficsimulation|Wool Crossing Traffic Simulation]], but for completeness is also included here:+The “Potential Traffic Impacts of Development in the Wool Area” (Referred to as PTI see Note2) provides the TRICS (Trip Rate Information Computer System) estimated trip rate for the extra 1000 homes where the Vehicles are leaving at 8am. This is given as 346 over the hour.  
  
- +The PTI uses a split of 55:45 split for West and East bound traffic. For this simulation the East/West split measured at Station Garage at 8am was used. It has also been assumed that the 1000 homes will not generate any extra HGV traffic.

-The Videos show that without the extra homes, the queue goes back as far at the Central Convenience Stores. Adding the extra vehicles caused by the 1000 homes makes the queue go past the current Purbeck Gate entrance and up towards the Winfrith Roundabout.+The Videos show that without the extra homes, the queue goes back as far at the Central Convenience Stores. Adding the extra vehicles caused by the 1000 homes makes the queue go past the current Purbeck Gate entrance and up towards the Winfrith Roundabout. This distance is about 600m or 0.4 miles.
  
-After the crossing opensthe tail back takes  +The original "Potential Traffic Impacts of Development in the Wool Area” (Note2) assessment predicted a maximum queue length of 82m (514m-432mpage 17, table 8.1). The simulations above show that the queue length from the extra 1000 homes is closer to 600m.

-The simulation does not take into account traffic coming from Lulworth into Wool past the Spar Shop. In previous [[woolcrossingtrafficsimulation|simulations]] adding this data shows that the traffic junction by the Station will become congested and a major traffic bottleneck. The simulation also does not take into account vehicles leaving from Wool that will add to the congestion along.+
