How frequently does IDOT conduct surveys of road conditions?

IDOT conducts surveys of road conditions annually to assess the quality and safety of the road network. This frequency allows the department to identify necessary repairs and maintenance proactively, ensuring that infrastructure remains safe and functional for drivers. Regular annual assessments help in monitoring changes in road conditions over time, enabling timely interventions and effective allocation of resources for road improvements. This systematic approach also supports long-term planning and prioritization of projects aimed at enhancing the overall safety and performance of the state's transportation system. The other options suggest less frequent surveys, which would not provide the timely data needed to manage and improve road quality effectively.
