Traffic calming & management strategy for a local distributor (Class 4) facility
2001 (English)Report (Other (popular science, discussion, etc.))
Abstract [sv]

Traditionally traffic calming has been applied to residential (Class 5) roads

to deal the need to eliminate extraneous traffic from a residential area

and/or to reduce speeds of vehicles using residential streets, both for

obvious safety reasons. Local distributor (Class 4) routes can be defined as

through routes that distributes traffic within communities and link district

distributors routes and residential streets. These routes may accommodate the

local bus/taxi routes, but should not carry extraneous traffic. Often non

residential land uses such as community facilities and commercial uses are

found along these routes. Local distributors therefore have both an access

and a mobility function. The mobility function of these routes has to be

preserved or else traffic will divert to the residential streets, thereby

resulting in a traffic calming problem. Requests for traffic calming on Class

4 roads lead to a trade-off between mobility and safety. The paper presents a

case study with the initial study of the traffic situation, the suggested

strategy and an after study comprising intersection turning movement counts

and travel time surveys together with accident data for the route and the

traffic flow data. Average speed has decreased drastically and the 85th

percentile speeds is now well below the posted speed limit. Vehicular flows

have reduced, thereby indicating that the reduced speeds on the route have

resulted in a diversion of some traffic to parallel routes. The frequency of

accidents has been reduced by approximately 80%, while the frequency of

slight injury accidents has reduced by approximately 70%. Over the past two

years, the occurrence of serious injury accidents appears to have been

eliminated.
