Chicago Arterial Street Pavement Condition Assessment Program

About this Project

Our team played an integral part in the implementation of a citywide GIS-based arterial street pavement condi­tion assessment program. This program was developed on the City’s Arterial/Collector street system which con­sists of approximately 1050 centerline miles (more than 2800 lane miles). We used our engineering knowledge and familiarity with City and State data sys­tems to effectively provide the following services: data creation and analyses, supporting documentation and data requirements, converting existing data files, map­ping, developing a citywide route system and linear referencing system (LRS), creating web-based mapping tools, and training City staff on applications developed to support the program.

The development of the Arterial Street Pavement Condi­tion Assessment Program provided CDOT with a valu­able tool for asset management. The visual inventory of arterial and connector roadways equips CDOT with improved capabilities to understand current conditions and allows for proactive decision-making on mainte­nance and planning functions that can maximize effi­ciency and minimize costs.

This database, designed using IDOT and CDOT datasets, allows the city to better understand where road mainte­nance is best suited, as well as manage road conditions using rational, condition-based decision making.
