Cambridge is a predominantly rural county, but one which has experienced higher than national traffic growth over the past 10 years. With increasing concern about air quality issues in Cambridgeshire, the County Council investigated the three waylink between traffic flows, air pollution, and ill health. The investigation was done in partnership with other authorities through the Air Quality Liaison Group with both tiers of local government and health authorities. It concluded that air pollution from traffic can exacerbate existing ill health although there is no firm evidence that it causes ill health. The effects of traffic flows, street geography, and weather on pollutant levels were studied. The results indicated that street geography has a critical effect on traffic related pollution and that pollution levels now appear relatively static. The high level of interest generated the political will to take action and many transport initiatives were implemented. Surveys show that these have been successful in improving the environment in the historic centre of Cambridge. They include: a) pedestrianisation of part of the historic centre; b) installation of an electronic bus gate; c) provision of park and ride facilities; and d) investigation into methods of managing demand for travel through a travel awareness campaign. Whilst the evidence is not conclusive, sufficient exists to indicate that positive actions should be taken to build on the work done so far. These actions will focus on the travel awareness campaign combined with ensuring that alternatives to the use of the car exist. (A) For the covering abstract see IRRD 877018.
