Title: City of Calgary's Pavement Management System - Performance Indices Comparison (Poster)
Abstract: Pavement Management Systems (PMS) combine engineering and economics to develop cost-effective solutions for pavement maintenance and rehabilitation. To achieve fact based decision making in managing and maintaining the network efficiently, the City has been using PMS since mid 1980’s. PMS measures the performance of the City’s pavement network and predicts future needs, which is used in developing budget needs at targeted level of service. Every year City invests in network level pavement data collection program to monitor functional and structural performance: Visual Condition Index (VCI) – Automated and manual surface distresses; Riding Comfort Index (RCI) – Pavement roughness (IRI); Structural Adequacy Index (SAI) – FWD on Arterial network. The City of Calgary adopts an overall combined index, Pavement Quality Index (PQI) as a performance measure in evaluating the network condition. While PQI gives us an overall picture of network level needs, this represents another level of aggregation and can involve loss of information. However, performance index is looked at independently at project level in prioritising the segments. Hence an attempt is made to compare the network level needs for overall pavement condition index with that of individual performance indicators to better understand the network condition as indicated by individual performance indicators.
