Impacts
Assessment Looks at Effects Plan has on Vital Factors
Introduction
The fiscally constrained 2050 Plan addresses the eleven planning factors as well as the federal performance measures. OKI has also developed this impact assessment to evaluate the effects the plan and 2050 Vision will have on several vital regional factors.
As described in the Recommendations section, a single scenario for each benchmark year represents the OKI 2050 Metropolitan Transportation Plan. In addition, OKI presents a vision for 2050 where we explore what’s possible when the extent of connected and autonomous vehicles, the amount of shared-use trips, and the vehicle ownership model is turned upside down.
OKI utilized its Activity Based Model (ABM) to estimate the impacts on travel at a regional level. The ABM is designed to estimate travel at the system and corridor level. It is sensitive to temporal and spatial elements of travel including travel times, cost, capacity, trip making, characteristics, mode availability, etc. For comparison, multiple 2050 model runs were performed to demonstrate the effectiveness of the plan.
The following summarizes each setup:

2020
representing existing conditions
2050 No Plan
uses 2050 trips with existing highway and transit networks and 0 percent CAV
2050 Base
uses 2050 trips with Recommended Plan highway and transit networks and 0 percent CAV
2050 Plan
uses adjusted 2050 trips with Plan highway and transit networks and 70 percent CAV
2050 Vision
uses adjusted 2050 trips with Plan highway and transit networks and 89 percent CAV
