Performance Metrics - Transportation - Pothole Repair

When moisture seeps into pavement, it expands when it freezes and contracts when it thaws. This flexing of the pavement, combined with the melted water and the stress of vehicular traffic, causes pavement to deteriorate and potholes to form. The Department of Transportation (CDOT) responds to potholes reported through 311’s Customer Service Requests (CSR) system by mapping open pothole requests each morning and routing crews in geographic clusters so as to fill as many potholes as possible per day. This metric tracks the average number of days CDOT takes to complete pothole repairs per week. Total number of requests fulfilled per week is also available by mousing over columns. The target response time for pothole repairs is within 7 days.

当水分渗透进路面时，在冻结时会膨胀，而在解冻时会收缩。这种路面的伸缩，结合融化的水分及车辆交通的压力，导致路面退化并形成坑洼。交通部（CDOT）通过311客户服务请求（CSR）系统接收到的坑洼报告，每天早晨绘制开放坑洼请求图，并将施工队伍分配至地理集群，以每日尽可能多地填补坑洼。本指标追踪每周CDOT完成坑洼修复的平均天数。通过鼠标悬停在列上，还可以查看每周完成的请求总数。坑洼修复的目标响应时间为7天内。如需了解更多关于坑洼修复的信息，请参阅CDOT的坑洼常见问题解答页面：http://www.cityofchicago.org/content/dam/city/depts/cdot/PotholeFAQ_winter1011.pdf
