October 31, 2005 – A simple measure taken by ICBC and the cities of Vancouver and Burnaby is
showing tremendous results in terms of road safety on some residential streets.
The program, called “stop sign infill,” consists of installing stop signs
alternately at every second intersection in residential neighbourhoods. The
goal is to reduce the frequency and severity of collisions in residential
neighbourhoods, and to produce a traffic calming effect in neighbourhoods
by discouraging motorists from using side streets as short cuts.
Two civil engineering experts completed an evaluation of the project
earlier this year. They examined 133 intersections in Vancouver that had
been part of the infill project, comparing them with the same number of
similar but unmarked intersections. Their evaluation indicated that injury
collisions were reduced by 50 to 80 per cent and collisions overall went
down by 40 to 60 per cent following this type of stop sign installation.
“Many different circumstances can lead to a change in the number of
collisions, but in this case we’re satisfied that the stop sign
installation was the significant factor in these results,” said John Pump,
ICBC manager of the Road Improvement Program.
“ICBC invests in road improvements and design because preventing crashes
means low and stable rates for our customers,” said Pump.
Sylvia Kirk of the City of Vancouver Engineering Services Department said
that frequent requests from residents for increased traffic control have
made the stop sign infill program a popular initiative. “Stop sign infills
have been in high demand throughout the City and we are committed to
improving traffic conditions for local residents.”
Stop signs were installed at approximately 1,450 residential intersections
in Vancouver and Burnaby between 1998 and 2003 in a joint project between
ICBC and road authorities in those cities.
ICBC’s Road Improvement Program works with communities to help them
consider safety issues in the planning stage of roadways and buildings;
takes on engineering and education efforts to help communities manage
traffic and roadways as safely as possible; and finds and tests new ways to
In 2004, ICBC contributed $6 million to road improvement projects
throughout the province, with additional funding provided by provincial and
local road authorities. Visit http://www.icbc.com.
