| 摘要： | The city of Burlington, with a population of 120,000 in Ontario, Canada, faced increased road rehabilitation needs and funding cutbacks. The city recognized the need for an integrated approach to maintain and improve its road infrastructure and achieved this with a pavement management system (PMS) in conjunction with asset capitalization and total infrastructure assessment. In 1990 the city initiated a complete review of its organization to reassess priorities, address functional deficiencies, and develop a long-term infrastructure management strategy. The city now makes effective use of its PMS to determine the present status of the road network, predict performance, and determine an optimum long-term rehabilitation program. The system assesses the condition of each road, predicts the year in which each road section will fall below a minimum pavement quality index, and recommends when cost-effective rehabilitation should optimally occur. City staff recognized, however, that the PMS tends to be biased toward high-volume arterial roads at the expense of low-volume local roads. To address the management of the entire road network, staff developed an innovative, integrated approach that incorporates both asset capitalization and total infrastructure management needs determination to complement the PMS. The road asset capitalization model uses the pavement quality index as the proportionate percentage of the remaining asset value, and it takes into consideration performance prediction curves as well as the life cycle of a road. The city has also developed methods for determining local street reconstruction priorities. Burlington has succeeded in introducing its PMS and integrating it into a cost-effective budgeting process. In view of this integrated approach to road infrastructure management, the city's program is viewed as a highly effective, proactive one that will assist the municipality in avoiding a road infrastructure crisis. |
