39 Technical Guide Introduction and Purpose This chapter provides an overview of the methodology used by the tool for assessing the value of intermodal connectivity and also providing instructions for its use. The tool can be used in conjunction with other tools developed through the C11 project to estimate the economic development benefits of a highway improvement.

40 Output and Calculations Connectivity Index The tool combines the data inputs into an index that will measure the connectivity value provided by the terminal and can be used to compare connectivity at different terminals. This can help prioritize and select highway improvements with access to terminals offering higher levels of connectivity.

45 of trucks at the infrastructure investment location accessing the intermodal location, which is calculated using an exponential distance decay factor based on the distance. This factor assumes that the further away from the intermodal facility that the roadway improvement occurs, the less impact it will have on the intermodal facility.
