We need better bus journeys between Cambourne and Cambridge

The nut – summarised

9.5 mile route, 80% uncongested
5 miles of dual carriageway A428: no significant congestion now
r forecast up to 2031
Parallel single carriageway St Neots Rd also uncongested
2.5 miles from West Cambridge site to city centre: minimal or no

congestion (about half on restricted streets)

Peak hours congestion on Madingley Rise in-bound in the

morning (ave 4 mins)

Negligible out-bound in the evening (20 seconds)
Citi 4 service is not very good:
Half an hour picking up in Cambourne
Keeps stopping en route to Cambridge
Rather slow and unpredictable in-bound in the morning rush

Segregated as far as West Cambridge site, whether

needed or not

Not segregated between Grange Road and the city centre,

where significant risk of congestion exists

“Present value cost” of £207m
£10-20,000 per resident
Environmentally damaging
Overwhelming public opposition
Long and difficult to implement (public enquiry, land

take, construction risks)

Oh, and it won’t actually work (i.e. drive modal shift)

re-summarised

SLIDE 20

A smart solution…

SLIDE 21

A different, solution-oriented approach for the LLF
People buy on benefits not technical attributes
Segregation:
not a worthwhile end in itself
useful to by-pass significant congestion – not worth it

where fast, uncongested roads already exist

on-line can be as effective overall as off-line (possible

advantages on flexibility, connectivity, convenience, etc)

SLIDE 22

TARGET BENEFITS

Fast, Frequent, Reliable
None of these likely to be materially better than car
Ease, productivity (not so useful on short journey)
Cost-effective (saving on petrol, parking)
Environmental benefits

SLIDE 23

A smart solution tailored to the actual need
Segregation where it’s actually needed and where it

will deliver benefit

Fit for purpose: adequately fast, frequent and

reliable journeys

Proportionate investment
Environmentally sensitive

OPTION 6

SLIDE 24

Cambourne to Madingley Mulch

High-speed, on-line service from Cambourne to Madingley Mulch, using existing, uncongested A428 (for express services) and St Neots Road (for stopping services). Appropriate on-line segregation and/or bus priority measures where needed to ensure free running of buses. Easy access to P&R via existing bridge over A428, if needed. Park & Cycle/Ride in vicinity of A428 junction at Scotland Farm, serving local communities along and beyond corridor and intercepting traffic prior to build-up of congestion.

SLIDE 25

Madingley Mulch to M11

Segregation and/or signalisation to allow buses to pass directly round or through Madingley Mulch roundabout without stopping for car traffic. Single/tidal or double bus lane along the centre of Madingley Rise, with tidal or signalised flow across M11 overbridge. Segregated off-road cycleway via Coton. Single bi-directional bus lane over existing M11 bridge

SLIDE 26

West Cambridge site to city centre

Easy connectivity with Western Orbital service to Addenbrooke’s Biomedical Campus. Easy connectivity through North-West Cambridge site to the Science Park. Pedestrian/cycle underpass between the two campuses. Some express buses could stay on Madingley Rd –

ptions to be

assessed. Service through West Cambridge site

n existing roads.

Bus/cycle transport hub on campus with dedicated cycle route to city centre.

SLIDE 27

In: 2.1 miles, 7 minutes Out: 3.7 miles, 13 minutes

Grange Rd/Queens Rd to city centre

SLIDE 28

In: 2.3 miles, 7 minutes Out: 2.1 miles, 7 minutes

Northampton St/Bridge St to city centre

SLIDE 29

Fit for purpose: all the benefits of an off-line

segregated scheme at a fraction of the cost

Attractive journey times: 20 mins to city centre, <

30 mins to Addenbrooke’s, Science Pk (at peak)

Financially responsible: appropriate investment for

A428 corridor (£32m)

Value for money: benefit-cost ratio > 1
Minimal environmental impact
Community support

OPTION 6

SLIDE 30

Strategic fit: greatly outscores other options
Supports HQPT: fast, frequent reliable journeys
Convenient & flexible: route and P&R accessible to

more communities west of Cambridge

Connectivity to Western Orbital scheme
Future-proof: either segregated or uses roads not at risk
f future congestion
Satisfies the Local Plan
Coherent with City Deal vision and local policy
