Impacts Overview

Assessment Looks at Effects Plan has on Vital Factors

This Plan explores the traditional and required fiscally constrained and air quality constrained planning approach as well as testing alternative futures in what is called 2050 Vision.

2050 Fiscally Constrained Plan

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 will have on several vital regional factors, including mobile source emissions and mobility.

OKI utilized its Regional Travel Demand Model (known as an Activity Based Model) to estimate the impacts on travel at a regional level. The OKITDM 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. To meet federal requirements OKI used the approved, validated OKI ABM for various scenario years of 2026, 2030, 2035, 2040, 2050, 2050 E+C.

OKI 2050 Vision

In addition to scenarios to meet the basic federal requirements, 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.

The following summarizes each 2050 Vision setup:
