Pricing Objectives

Traffic Impact Assessments/Transport Appraisals suggest that there will be an additional 20,350 ‘new’ trips (all modes) in the morning peak period by 2021, an increase of approximately 20% compared to 2006 figures. This is predicted to cause increased delays on major routes in the county.

In the city of Cambridge city itself, increased levels of congestion are predicted to cause:

  • 84% increase in junction delays;
  • 30% increase in distance travelled; and
  • 46% increase in travel time.

The figure below illustrates the results of traffic modelling and the predicted number of trips given various scenarios.

In a ‘do nothing’ scenario, the number of car journey trips is predicted to increase to over 300,000 by 2021 from a baseline of approximately 275,000 in 2006. This is shown in the ‘Projected 2021 journeys’ column in the figure below.

The predicted impact of a ‘combination of improvements’ or measures, indicates a fall in the number of car journeys to approximately 260,000, if substantial public transport, walking and cycling and highway improvements are introduced. This package of measures is considered an important component of the proposed scheme.



In support of the package of measures already mentioned there are a number of improvements that are planned and these are shown in the following figure.

The proposals, as illustrated, include:

  • Restricted Access to Cambridge along the key roads entering the city to the north and south;
  • Junction improvements at 4 key locations in the central area of Cambridge;
  • Highway improvements:
  1. On part of the orbital road network to the east of the city (access from the A14);
  2. On the main route into the city from the M11 to the west of Cambridge.
  • Public Transport Improvements along a number of key routes into the city;
  • Cambridgeshire Guided Busway to the north and south of the city; and
  • Improvements to a number of Park and Ride sites at strategic locations around Cambridge.
