§ Mrs. MayTo ask the Secretary of State for Transport, Local Government and the Regions if he will list the 227W projects for which the Highways Agency's NAOMI traffic flow model has been used in the last six months. [16596]
§ Mr. ByersDuring the last six months, the NAOMI traffic model has been used to predict traffic flows for the following projects:
- The ORBIT multi-modal study, which covers the M25 corridor
- Proposals for service areas on the M25, M4 and M40.
Additionally, during the last six months information from the NAOMI model has provided input to developing the traffic forecasts for the following projects:
- The Reading Area Transportation Study
- A simulation model of the M25 junctions 10 to 16
- Research into trip movements at motorway service areas
- A proposed motorway service area on the M27 at Meon Valley
- An investigation of M25 Junction 13 and Glantry roundabout
- Highways Agency development control
- An investigation of development opportunities in Thames Gateway.
§ Mrs. MayTo ask the Secretary of State for Transport, Local Government and the Regions when the NAOMI traffic flow model was introduced by the Highways Agency; and what assessment has been made of its reliability and accuracy. [16595]
§ Mr. ByersThe NAOMI (New Assessment of Motorway Improvements) traffic flow model was introduced originally in 1995 and has been subject to several revisions and updates. The current version has been in use since September 2001. The reliability and accuracy of the model has been assessed using procedures contained in volume 12a of my Department's Design Manual for Roads and Bridges and passed as being fit for purpose as a regional scale model.
