Chicago – St. Louis passenger rail ridership and revenue forecasts
Illinois Department of Transportation
The Illinois Department of Transportation (IDOT) is considering several infrastructure and systems improvements to the Chicago – St. Louis Amtrak rail alignment that would improve the speed and capacity of travel on the corridor.
Improvements under consideration include construction of a second main track; rehabilitation of the existing mainline; and installation or upgrading of train signaling systems.
Steer Davies Gleave will be developing ridership forecasts for the Tier 1 NEPA document that IDOT is currently preparing for passenger rail service improvements on this corridor.
How we did it
This study will use our existing well-tested rail/HSR forecasting methodology to predict the probability that travelers will divert to improved rail/HSR from conventional modes such as auto and air, as a function of the modes’ service attributes and traveler characteristics. The model has proven its robustness and reasonableness across applications to many rail/HSR corridors in the US.
Components of the study include:
- Establishing the current pattern of inter-urban tripmaking in the corridor, with data collection including analysis of anonymized traveler movements obtained from cell phone use within the corridor.
- Predicting the effects on inter-urban mode splits of improving Amtrak service in the corridor.
- Ridership forecasts for the improved rail system, which will consist of both diverted trips and induced trips, which formerly were not made, but which are caused to be made as a result of the improved passenger rail service.
