There are approximately 410 lane-miles of pavement markings within the City. The performance target is 60 lane-miles (5 lane-miles per month). The bulk of this work is done by contract during a five-month period, so monthly totals over the year will vary. The contracted work is typically completed in the dryer months of September to March. Pavement markings are refurbished to provide good reflective qualities for night time driving. The visual qualities of pavement markings have a direct relationship on the frequency of vehicle, pedestrian and bicycle crashes that are the leading cause for fatalities, severe injuries and property damage. Refurbishing is done to enhance public safety.
