- Congestion costs Chicago area businesses, truckers and commuters over $4 billion per year.
- The number of trucks on Chicago area roads is expected to increase by at least 80% in the next 25 years.
- Congestion is the result of several key factors such as:
- Physical bottlenecks - when a certain section of roadway reaches its maximum carrying capacity.
- Traffic incidents or any event that disrupts the flow of traffic including debris and vehicle crashes/breakdowns.
- Work zones or any physical change to the roadway including lane shifts, lane reductions, shoulder closures, and temporary roadway closures.
- Weather and other natural phenomenon that change driver behavior and roadway conditions.
- Traffic control devices such as railroad crossings and poorly timed traffic signals.
- Special events such as a sports game or concert that causes the area of the event to have a surge in traffic demands.
- Fluctuation in normal traffic such as the morning and mid-day rush hour.

- Because of congestion, approximately 5.7 billion gallons of fuel are wasted annually - nationwide.
- Research for the trucking industry has shown that shippers and carriers value transit time in the range of $25 to $200 per hour, depending on the product being carried. The cost of congestion and unexpected delays can add another 20 to 250 percent.
- Other costs to businesses include:
- The cost of remaining open for longer hours to process late deliveries.
- Penalties or lost business revenue associated with missed schedules.
- Costs of spoilage of time-sensitive, perishable deliveries.
- Costs of maintaining greater inventory to cover the undependability of deliveries.
- Costs of reverting to less efficient production scheduling processes.
- The additional costs incurred because of access to reduced markets for labor, customer, and delivery areas.
