摘要

道路品質的良窳是城市進步的指標，隨著新北市升格後帶來的人潮，觀光經濟發展、交通運輸需求量與日俱增，使道路負荷沉重也更容易損壞，已嚴重影響通行品質甚至安全，因此推動路平專案措施，逐年完成全巿道路更新、整平，徹底改善道路體質，以打造新北市友善環境。
對於用路人行車舒適度而言，最直接的感受即為道路平坦度與否，若是道路平坦度不良，民眾投訴及陳情將接踵而來，也造成地方行政機關行政效率最直接的影響，為提升社會大眾通行品質，新北市政府將「路平、燈亮、水溝通」列為施政重點，而其中路平則居於首位，為提升道路鋪面品質，降低坑洞之產生，提供市民安全舒適的行車空間。
本研究係針對新北市政府「路平專案」於101年度已完工道路作為研究範圍，並以IRI實地檢測驗證法及運用統計分析法分析比較，其結果顯示施工前IRI值主要分佈於3m/㎞至5m/㎞，平均4.69m/㎞，施工後IRI值主要分佈於2m/㎞至4m/㎞，平均3.14m/㎞，表示受測路段IRI值呈現下降趨勢，顯示實施「路平專案」後對於提升道路平坦度有顯著之成效。最後並提供路平專案後續管理精進策略建議作為，期能延續鋪面品質改善成效，以提升道路使用年限及行車舒適性。

The sign of a city’s progress is the quality of the roads. More people live and visit New Taipei City after it’s upgraded, which leads more demand of tourist and economic development and transportation. As the result, the load of road is getting heavier and easier to be damaged. The quality and safety of traffic is deeply affected by then. This is why we need to start the project of the perfection of roads: to renovate, leveling and improve the quality of the roads in the city, and make New Taipei City a more friendly environment.

The most direct experience for people on the road is how smooth the roads are. More complaints are followed by the worse of the road condition. Which affect the administration efficiency of the local government the most. In order to improve the public transportation quality, the most important achievement of New Taipei City are: perfection of the road surface, brightness of lights and fluency of water. The perfection of the road surface is the top target among these three.

This research aims at roads that were completed under the project: New Taipei City Government promoting Road Improvement Work. In 2012, it applied IRI examination method and statistical analysis to analyze and compare road flatness rate. The result shows that IRI statistics at between 3m/km to 5m/km; average of 4.69m/km before the project, and 2m/km to 4m/km; average of 3.14m/km after the project.. This means the IRI ratio is on the downside. There is an obvious improvement of smoothing the road surface after this project was implemented. Here we provide the suggestions and strategy management plan of the post- project of “pavement smoothness project”. We also expect to last the efficiency of the surface quality so as to increase the period of road usage and the comfort of driving.
