Grundlagen zur Beruecksichtigung des 'Aufenthaltes nichtmotorisierter Verkehrsteilnehmer' bei Wirtschaftlichkeitsuntersuchungen

Abstract

The level of stay utilizations and the level of cyclist and pedestrian traffic was determined with the aid of video cameras in the vicinity of roads with different zoning structures. The dominating influence on the level of stays is the presence of shops; only low levels arise in the area of roads with dwellings. Stays arise only to a limited extent from cyclist traffic; pedestrians indulge in stays to a significantly greater extent. The level of stays increases with the level of the pedestrian traffic. The separating affect of motorized traffic and limitations in the areas for stays can reduce the level of stays. When applying the RAS-W guideline, surveys have to be carried out to determine the level of cyclist and pedestrian traffic in order to determine the number of cyclists, pedestrians and stayers. The level of stays can be derived form the level of pedestrian traffic via a regression approach. The evaluation of the noise pollution suffered by non-motorized traffic participants is carried out using an avoidance cost approach based on the cost of sound-insulation walls. Benefits resulting from changes to the level of pollution with noxious substances are evaluated with the cost approaches for residents, whereby the number of non-motorized traffic participants affected is weighted lower than the number of residents. The evaluating of the separating effect of traffic and of the areas for pedestrians and cyclists is proposed as an extension of the catalogue of benefit components in the RAS-W guideline. The cost approach for the separating affect of traffic is based on the time-costs of one pedestrian hour and the time losses for pedestrians waiting to cross a road. Target widths are defined for areas for pedestrian ways and cyclist ways; the cost approaches for these result from the costs for the production of paths and ways of these widths.
