Vehicular Cycling
Shared Space
Segregation

What conditions do we need to create in
order for (many) more people to consider
cycling a safe and attractive form of
transport for many everyday journeys?

“The Dutch don’t do
that…”
(is not enough reason to
dismiss an idea)

The Network

Cycling network plans ultimately need to be more than ‘desire lines’ on a map

Hard to see here, but Munich’s cycle map is a good one

Cycling Level of Service assessment is useful – but may need a ‘lite’ version

Links

• Royal College Street Phase 1 scheme implemented 2013.
• Cycling volumes increased by 70% from 2011 to 2014.
• Cyclist injury rate before was 4/year; rate in 15 months after
was <2/year (none ‘serious’).
• Difference in the % of women cycling on RCS compared to
alternatives varied from 9% to 17% depending on period.
• Difference in the % of people cycling in normal clothes on
RCS compared to alternatives varied from 8% to 24%
depending on period.
• Few young or old people (<18 years and >60 years) were
observed on RCS or alternatives, though the proportions
were appreciably larger on RCS than alternatives.

Bristol. ‘Light’ segregation? These will break your car!

New track in Baldwin St, Bristol

Badly-articulated entry (outside the ‘red line’) reduces utility of this new track in
Southampton.

CS3, Cable St. Possible ‘Cycle Street’

• Key to the success of ‘Cycle Streets’ is for motor traffic
speeds and volumes to be relatively low, and cycle volumes
to be relatively high.
• Max speed limit must be <20mph or less.
• Advised max daily traffic flow is 2,000 vehicles in the
Netherlands (CROW Manual) and 3,000 in Germany.
• Cycle volumes should be no lower than those for general
traffic, and ideally higher.
• Dutch guidance states Cycle Streets should have (potential
for) flows of at least 1,000 cycles/day and that cycles should
generally outnumber other vehicles 2:1 during peak hours.

Vehicular Cycling?
Shared Space?
Segregation?

• Paths away from traffic altogether
• Streets where traffic is quiet
• Segregation on busy streets

Junctions
