Effectiveness of performance indicators in managing road networks

Performance specified maintenance contracts (PSMC) have been operational in New Zealand for over six years. These contracts are driven by key performance indicators that define the expectations of the road agencies. Key performance measures (KPM) are used to monitor progress and performance of the contractor. KPMs are the primary means of the road owner to express its expectations and enforce those through the maintenance contracts. As the effectiveness and efficiency of the KPMs is vital to achieve the desired results, it is essential to examine the effectiveness of the current KPMs to control and direct the maintenance contracts. The validity of current KPM definitions and their statistical interpretation in particular was explored. The most frequently used statistical term, the average was found not always fully satisfactory. A practical alternative was evaluated and checked against data obtained on four selected networks in New Zealand. The recommended measure and procedure allows a more representative summation of network data. The closer representation of the true network condition has significant impact on the management of performance based maintenance contracts and provides a tool to evaluate the reliability of the collected data quickly.
