Drive Traffic Calming Process Flawed
of North Vancouver has not followed its own traffic calming policy when it
installed the speed humps on Riverside Drive.
calming policy in effect in 2001 in the District of North Vancouver is an
ammended version of the Hamilton Associates Traffic Calming Programs and
Procedures report which was accepted by council in 1999.
version of the document submitted by Hamilton Associates stated that:
calming measures would generally only apply to local roads which are not bus
routes or major emergency routes in the District of North Vancouver. Section
1.3 of 1999 Traffic Calming Policy
subsequenty ammended by a recommendation to council from the Transportation
is a recommendation from staff that minor collector roads also be included
in the policy. Attachment 2 of 1999 Traffic
definitions were also clarified in this recommendation:
Roads: The main function is to provide property access. Traffic movement
is of secondary importance and primarily involves travel to and from a
collector facility. Trip length is short.
Roads: The main function is to collect and distribute traffic into and
out of a neighbourhood, and provide property access.
collector Roads: Those collectors that are not a bus route and not a
major emergency route.
Roads: The main function is to carry trips of longer duration and
through traffic, as well as accommodate significant volumes of traffic.
is at least a minor collector road and at most a collector road. It is the
major emergency route for all 261 homes in Seymour Valley East but is not a
bus route. It collects traffic from Treetop, Riverbank, Rivergrove, Chapman,
Edgewater, and Swinburne.
The traffic policy was
not followed in the following ways:
Support: At least
50% of homes must return their surveys and the majority of these must
support traffic calming. Section 2.2 of 1999
Traffic Calming Policy Only 44% of our homes returned
their surveys. 107 surveys were returned Context
report p4 from a total of 261 homes residents
- No consensus
was reached: The meetings will use group
decision making techniques to encourage consensus building toward the
selection of a preferred solution. Section 3.4
of 1999 Traffic Calming Policy Strongest support was for doing
all of the traffic safety improvements Context
No concensus was reached to do only the 4 speed hump option and no vote
was taken at the second meeting to confirm what the preferred solution
was. The option to do "No traffic calming" was conspicuously
absent from the list of alternatives presented. Attendees were requested
to drive over existing speed humps and most expected that a third meeting
would be held.
- Funding by
the district: Funding
of traffic calming projects will only be considered for those projects
where the existing conditions in the neighbourhood exceed at least one of
the minimum operational thresholds shown in the following table Section
4.1 of 1999 Traffic Calming Policy:

Riverside drive meets none of these criteria. Infiltration is 0%
since there is only one way in and one way out. The 85th percentile was
14.5k/h over the posted speed limit and the traffic volume
was 2180 on Feb 22, 2001 Report To Council
