Cambridge Futures progress
• Cambridge Futures Phase 1 - transport was the
main issue
• Phase 2 is developing transport options
• Aims to test them using the County Council land
use/transport model
• Liasing with the County Council to develop the
Structure Plan model to form a 2016 base for
testing the options.

The scale of development
• Sub Region
– new dwellings (29% increase 1999 to 2016)
• Cambridge urban area
– new dwellings (38% increase 1999 to 2016)
• The majority of new dwellings in the Cambridge
urban area are more than 2 km from Cambridge
city centre

Potential transport effects of the
What Transport for Cambridge?
Draft Structure Plan
• High traffic growth between 2001 and 2016
– Sub Region 30%
– Cambridge urban area 35% to 40%
(Source of estimates: Cambridge Futures Phase 1; TEMPRO trip end
forecasts)
• Increasing traffic delays of up to 200%
(Source of estimate: Cambridge Futures Phase 1)
• ‘Peak spreading’

Potential consequences
2
• Economic
– increasing production costs
• Environmental
– increasing air pollution, and poorer environmental
quality
• Social
– lower socio-economic groups would be
disproportionately affected by traffic congestion
• It may be difficult to achieve the projected levels
of development without substantial investment in
transport

EiP Session 4A: Will the policies
deliver a sustainable spatial strategy?
• Overall transport policies emphasise increasing the ability to
move by cycle, public transport, and on foot.
• They propose the development of high quality public transport,
(HQPT), services, defined according to service frequency.
• The priority measures are not clearly defined for urban areas.
• The measures rely on a reallocation of road space at a time when
there will be a major increase in traffic demand.
• Fiscal demand management could free up some road space for
public transport priority measures - Plan needs to be more
specific about the fiscal measures to be considered.

Concerns about the transport
What Transport for Cambridge?
investment priorities
• Modal split assumptions seem too high.
• Traffic growth on the A14
– More traffic than expected in the NW A14 corridor
– Traffic from development east of Cambridge
– potential effects of proposed Alconbury hgv depot?
• Feasibility of accommodating all of the rail improvements?
Can the Cambridge to Newmarket service be improved? Is
there also room for rapid transit?

Concerns about the transport
investment priorities continued...
• Transport investment is focussed on corridors into the city
centre - and does not cater for the growth in cross-city
travel.
• 1991 Census data shows that for Cambridge two-thirds of
work trips are more than 2km. Many of these longer
journeys are likely to be by car.
• Some investment in ‘orbital’ transport capacity is required.

Options being tested by
Cambridge Futures

Public transport?
Congestion road pricing
Orbital highway
Improved cycling and walking facilities
A combination of the options
• These options have still to be tested using a land use
transport model and some elements may be added or
omitted depending on the results.

Public transport option
• Extensive network, as shown in the following Figure.
Rapid transit would include segregation and priorities.
• Extra park and ride sites.
• A route connecting the park and ride sites and linking the
nodes of edge development.
• Possibly a tunnel from the West of Cambridge under the
City Centre to the Newmarket Road corridor
• An inner circular system, possibly a one-way service
given the physical constraints.
• Also includes the Draft Structure Plan HQPT proposals.

Congestion Road Pricing
• Congestion road pricing will be tested as an example of
fiscal demand management.
• It would consist of a cordon of tolling points around
Cambridge as shown in the following Figure.
• The charges for vehicles crossing the cordon would be £3
during peak periods with a lower charge off-peak. There
would be a charge of around £0.50 for journeys within the
cordon.

Orbital Highway

• The orbital would form an outer ring road linking the
edge developments.
• It would enable drivers to access the park and ride
site that passes closest to their destination.
• The scheme would include either link roads parallel
to the A14 and M11, as shown on the following
Figure, or a separate parallel route. The orbital
would cater for local traffic with long distance through
traffic using the mainlines of the A14 & M11.
• Tunnels would reduce the environment impact
around the south east of Cambridge.

Cycling and walking
• Extension and improvements to the cycle network, perhaps
using new bridges and rights of way.
• Cycle storage and hire facilities at transport interchanges
• Expansion of the pedestrianised areas
• Improved walking links along pedestrian desire lines.

Conclusions
2
• Structure Plan should not preclude the possibility of an
orbital route - assess before the Local Transport Plan
Review July 2003
• Cambridge Futures understands that the results of latest
run of County model will be available in time for the
transport sessions EiP.
• Major transport investment is required, £0.68 to £0.70bn
excluding the £0.3bn required for the CHUMMS
recommendations, (Roger Tym Report).
• A major transport study would be worthwhile, perhaps
building on the work done by the A14 CHUMMS study.
