Abstract
Patrol survey is a widely used method for data collection in parking studies, and one of its goals is to obtain the average parking duration for a parking area. However, the inaccuracy is unavoidable; one main reason is that short stay vehicles are often not observed. To reduce the error from the survey, short observation intervals can be chosen, but that can be very expensive. In this article, a generalized analytical model is built to analyse this error, several suggestions are made to guarantee the accuracy, and to coordinate it with the survey costs. Through dimensional analysis, the relation between time length of observation interval, estimated parking duration, and survey accuracy is illustrated. In the numerical example, a correction for the value of average duration is introduced to increase the accuracy. We further used simulation-based examples to extend the model and the conclusions to more generalized situations. The final result shows that with this approach, the accuracy of the survey could be estimated and enhanced. It helps the surveyors in choosing a proper length for the survey interval, so one could obtain high quality results from the patrol survey while keeping costs to a minimum. Show more
