A Brief Comparison on Traffic System Between London and Shanghai
Allen Liu, ShanghaiFeb. 16th 2012
Highlights
• Differences in road networks
• Public transportation differences
• Policies on managing traffic demand
• Others interesting
Differences in road networks
• the narrower roads in UK cities with higher density. the wider roads with lower density in Shanghai.
cities Proportion of major road s
Density of road networks
London 12.04% 8 (km/km2)
Shanghai
20.90% 6.7(km/km2)
Merits of the road networks in London
• Easier management of traffic flows;
• Reduction of the signal phase in the road
junctions to minimize the travellers’ delay
and potential risks of traffic accidents;
• Better accessibilities for travellers to their
destinations;
• Passengers are able to cross narrow road
more conveniently and safely.
Public transportation differences
• Essential factors of public transportation
between London and Shanghai
Something can be seen
※More than 95 % Londoners live within 400
metres of one of bus stops and tube
stations . Whereas, only 90% of citizens
are within 500 metres of public transit
stops in downtown Shanghai .
Something can be seen
※ The fares for public transit in London
increase quickly and sometimes out of
service because of private ownership.
※ Off-peak policies are used widely.
※ Buses in Shanghai are less reliable
because they always delay during peak
time.
Policies on managing traffic demand
• Traffic Demand Management(TDM)
• Roles of congestion charges
• Achievements in London and Shanghai
• Further improvements
Importance of TDM
• Switching from private to public transport
• Encouraging the redistribution of the
demand in space and time to balance the
demand and the supply
• No financial or economical feasibilities to
provide continuous additional capacity for
the service
Roles of congestion charges
• One of the most effective and efficient
method on managing traffic demand.
• To reduce vehicles and change
distribution of the demand to improve the
shortage of traffic supply by increasing
travellers’ prices during peak time and at
the places where congestion appears.
Congestion Charging Zone in London
• Implemented since 2003, even expanded
in 2007
Achievements in London
• 20% reduction in traffic volumes (about
20,000 vehicles per day).
• 15% Reduction in CO2 emission.
• Traffic accidents declined 40-70 times per
year.
• Additional money from charging.
Further Improvement?
.※Rational scheme should
charge vehicles based
on the number of their
travelling
※Some important
congested corridors
should be included
within the scheme.
Bedford Road congested for an average of
92 hours a week or more than 13 hours a day
Actions in Shanghai
• The auction of car plate has been held
monthly in order to control the amount of
cars since 1994.Total income in 2010:
Total Income(million RMB)
Subsides for transit
ticket prices
Free tickets during
off-peak for elder people
Investment for
subway
4150 1940 460 1750
Actions in Shanghai
• The policy of Off-
peak free tickets for
elders need to be
expanded.
.
Actions in Shanghai
• Increasing parking fees in city centre,
especially for road parking
Others interesting
• UK’s comprehensive ranges of principle
and actual actions “put people foremost”
should be adopted to Shanghai.
• UK reliance on roundabouts for managing
junctions, but the green wave policy may
be more useful on the major road.
Thank you!
