Use of Permanent Traffic Recorder Data to Develop Factors for Traffic and Truck Variations

摘要

This project entailed the development of the following four traffic volume adjustment factors from 1995 and 1996 permanent traffic recorder data: (1) A truck (axle) adjustment factor for single pneumatic tube counters (2) A factor for estimating Design Hourly Volume (DHV) from Peak Hour Volume (PHV) (3) A factor for estimating the % trucks in the Average Daily Traffic (ADT) from the % trucks in the PHV (4) A factor for estimating the % trucks in the ADT from the % trucks in the typical hours in a manual classification study, which are 7am-10am, 11am -1pm, and 2pm-6pm.
