ABOUT THE MAPS

These maps show characteristics for the area known as the "Oxford to Cambridge arc". They use 2011 census data, which is only for journeys to work.

Clicking on the pastel buttons on the left show different travel characteristics.

There are maps for journeys of residents from the 'home' end, and also for travel to work from the 'jobs' end. Jobs are more concentrated than homes, so some show as large circles.

The circles are coloured roughly as:- So green doesn't necessarily equate to 'good', nor red to 'bad'

The text boxes below change when you change maps.
POLICY IMPLICATIONS

A proposal to build an "Oxford-Cambridge Expressway" accompanied by up to one million new homes is currently under consideration. The implications for motor traffic could have major impacts on pollutant emissions, congestion on other local roads, and climate change.

The text accompanying these maps, which changes when the maps are changed, provide commentary based on current travel to work patterns using 2011 census data. The left hand part describes the patterns, while the right hand column has some conclusions for that map.

General Conclusions

While central Oxford and Cambridge are national leaders in terms of 'green' travel (along with central London, Brighton, Bristol, York and a small number of other places), the strong message seems to be that it would be extremely difficult to provide large numbers of extra homes and jobs without generating very high levels of car traffic. For residents, besides central Oxford and Cambridge very few areas besides those close to stations with a good service to London or areas close to the centre of established town centres display high levels of active or public transport travel.

For employment areas, again, only the central areas of established towns and cities show 'sustainable' travel patterns.

In the current policy climate of relaxed planning and the lack of a very concerted to encourage active and public transport it is hard to see even moderate development leading to anything other than high levels of car use. It is also difficult to see how any route chosen for the 'expressway' would lead to much of the generated traffic actually using the road (except if the distances involved were even longer than expected). Most likely existing roads would see much high levels of traffic than they do now, with increasing congestion. Electric vehicles and automation (if and when it arrives) would not solve the congestion issues.

Kilometres driven per resident
Total driver kms for zone, divided by the working population.
The built up areas of Oxford and Cambridge (and London) show green or yellow which means low car mileage generation. The central areas of other larger centres show some yellow along with amber. Smaller but quite substantial and expanding towns such as Bicester and Aylesbury show red, and even mauve (the highest). Mauve predominates in rural areas and small towns which is not surprising, since there are few travel alternatives, and jobs are generally at some distance.
Policy related conclusions
It seems that Oxford and Cambridge are unique in their low car mileage generation, and that while older established large settlements (over about 80,000 population) fare quite well, newer and smaller settlements generate high car mileage.
