  The Use of A Toll Road in Birmingham, UK to Improve Air Quality

Example

   

Overview

The motorway network in the UK has historically been funded by Central Government, and has been operated without the use of Tolls. The West Midlands Region suffers from severe congestion on it’s motorway network. In particular the M6 motorway which was built to carry 72 000 vehicles per day was carrying 165 000 vehicles per day. As a result the Government has allowed the construction of the UK’s first privately owned motorway to relieve this congestion.

The M6 Toll Road has a length of 47Km and was opened in December 2003. Construction of the road cost £900m (1400m Euros) and was funded by a private company. The company has the right to operate the road for 53 years, after which time ownership returns to the Government.

The M6 Toll Road connects the M6 Motorway north of the West Midlands conurbation to the M42 Motorway to the east of the conurbation. This is shown in Figure 1 below. In this way the M6 Toll Road keeps traffic out of the heavily populated area in which air quality is poorest.

The Impact of the M6 Toll Road

The M6 Toll Road is still relatively new, and therefore changes to traffic levels are still continuing. However, the new road has resulted in a reduction in traffic levels of approximately 10% in the motorway network. This has had a very significant effect upon congestion on the motorway network. This is shown in Figure 2 below.

Figure 2 – The Effect of the M6 Toll Road upon Journey times on the M6

Figure 2 shows the average journey times on the M6 before the M6 Toll Road was opened (red), the average journey time on the M6 after the Toll Road was opened (dark blue) and the average journey time on the M6 Toll Road (light blue). This shows that the new M6 Toll Road has had a very significant impact upon congestion at peak times.

The high levels of congestion on the existing motorway network have resulted in air quality objective levels being exceeded in many locations across the West Midlands region. Work is ongoing to evaluate the improvement in air quality resulting from the reduction in congestion since the M6 Toll Road opened. However, it is anticipated that air quality within the conurbation will be improved significantly due to the new road.
