In Chicago, a 2004 feasibility study indicated that automated truck-way technologies (automatic truck steering, speed, and platoon spacing control) would be economically feasible by 2015 assuming there was an increase in demand and lower relative costs for future deployments.
ANALYSIS OF CVHAS APPLICATIONS FOR TRUCK/FREIGHT MOVEMENT
Using available rail rights-of-way, a new truck-only facility was proposed to serve a selected set of intermodal rail yards, industrial parks, and points-of-entry to the region. The following CVHAS technologies were evaluated to determine their impacts on truck operations:
- Automatic steering control
- Automatic longitudinal control in platoons
- Fully automated driving
- Baseline (no CVHAS technologies, no truck-only facilities)
- Truck-only facility without CVHAS technologies, open to all trucks
- One standard 12-foot lane in each direction prior to the Year 2015, and a second lane added for several segments of the facility by the Year 2015
- Truck-only facility with CVHAS technologies (automatic steering) for equipped trucks only
- One 10-foot lane in each direction. Automatic steering control makes it possible for equipped trucks to follow lanes very accurately. For maximum width trucks of 9 feet, lanes need only be 10 feet wide rather than the standard 12 feet
- Truck-only facility with fully automated CVHAS technologies (automatic steering, automatic speed and spacing control with two or three truck platoons if warranted) for equipped trucks only
- One 10-foot lane in each direction
- Truck-only facility without CVHAS technologies before Year 2015
- At Year 2015, upgrading the facility to be an automated truck-way (automatic steering, speed and spacing control with two or three truck platoons)
- One standard 12-foot lane in each direction
- The costs associated with each alternative included the following primary cost categories:
- Construction costs of truck-only roadway
- Right-of-way costs
- Annual facility operation and maintenance cost
- CVHAS equipment and installation costs (facility)
- CVHAS equipment and installation costs (vehicles)
The benefits for each alternative were limited to estimates of travel time savings and reductions in fuel consumption.
The Chicago Area Transportation Study (CATS) travel forecast model was used to estimate the impacts of CVHAS on the proposed facility for the year 2003. These data were further extrapolated to estimate impacts in future years.
For comparison purposes, the evaluation results below—excerpted from Table 4.16 of the report—are expressed in terms of 2003 dollars.
CVHAS costs (facility)
CVHAS costs (vehicles)
Travel time savings
Reduction of fuel consumption
Factors that had significant influence on each alternative included: Construction costs; CVHAS in-vehicle unit cost; and Travel time savings. A sensitivity analysis was conducted to account for uncertainties associated with these factors and a Monte-Carlo analysis was performed to determine if these factors were independent. Accounting for increased demand and the assumption that the relative costs of each technology would decrease in future years, a t-test indicated that Alternative 5 was economically feasible compared to the baseline case with no truck-only facility.
