METHOD TO DETERMINE OVERALL LEVEL-OF-SERVICE OF PEDESTRIAN WALKWAYS BASED ON TOTAL UTILITY VALUE

Abstract

This research proposes a method to estimate the overall level-of-service (LOS) of pedestrian walkways. It is based on the concept of total utility value, which comes from a conjoint analysis research. To estimate the total utility value for pedestrian walkways, field measurements were canied out by collecting operational and geometrical characteristics of sidewalks. Calculated total utility values were used to assign an overall LOS designation to each sidewalk, based on an assumption of a linear relationship between total utility value and overall LOS. To validate this calculation method, a pedestrian survey was conducted. The scores given by the pedestrians had a linear correlation with the overall LOS assigned for each sidewalk based on total utility value. This indicates that the total utility value can used as an index of the overall LOS of pedestrian walkways.
