A Generalized Procedure for Determining When Street Maintenance Activities Should be Allowed

Street lane closures are necessary for transportation infrastructure rehabilitation and construction projects. Closures can be preplanned by allowing lanes to be closed when traffic demand is less than the remaining capacity of the streets. The objective of this study is to consider all available 24-hour traffic volume counts available for Austin streets, compute lane and street capacities, and determine the daily hours when traffic demand could be served with a lane closed. Moreover, with these potential closure hours as a basis, identify zones where specified streets will have similar lane closure times with as little variability as possible. Traffic Analysis Zones (TAZ’s) were chosen to depict the geographic areas and six overlays were constructed using travel direction and street type to form sub-classes to minimize lane closure time variability within each zone. The overlays were presented using ESRI ArcGIS. It was found that available traffic volume counts were sufficient to delineate zones with streets and street sections of similar lane closure times. However, many streets had no count data available, therefore, they were not attributed to any zone. Moreover, this methodology could be used to expand the overlays should traffic volume counts of more streets become available.
