Abstract

In the Highway Capacity Manual of 1985, no levels of service (LOSs) for cyclists on separate paths are given. In the framework of the Dutch manual on bicycle infrastructure, a measure of quality of operation was developed: the hindrance that users of the path experience due to their interactions or maneuvers. Simplifying this to the frequency of passing and meeting maneuvers, the well-known LOSs from A to F can be defined. A new point is that LOS F is not merely a congested state of traffic, but is defined as a very poor overall quality of traffic operation. This approach was then extended to traffic operation on separate narrow paths used by pedestrians and bicyclists. Using this method the LOS can be determined separately for pedestrians, bicyclists, and the average user of the path. LOSs are a function of the volume of both types of users.

RESULTS appeared consistent, but some key parameters used as an input of the procedure have to be estimated empirically in applying this method. That is, they should be based on investigations of rating of maneuvers in terms of hindrance. The results can be used to determine requirements for path width and criteria for separation of bicycles and pedestrians.
