Travel Demand Model Updated Transit Network, Mobile Emission Estimates
Travel demand is one of the critical factors considered in transportation investment decision making.
The travel demand model is a computer tool that estimates traffic and transit volume. Those numbers are based on land use patterns; socioeconomic characteristics of the population and employment; and the composition and configuration of the transportation system.
OKI is the only agency in the region that owns, develops and operates a regional travel demand model.
The model is constantly being monitored, updated and enhanced.
In 2021, OKI’s transit network was updated to incorporate Phase I of Reinventing Metro Plan, the TANK system redesign, and other transit service and fare changes in the region.
The latest changes in major roadways, such as re-configurations, new interchanges and roundabouts, were coded into OKI’s highway network.
OKI’s Activity-Based Travel Demand Model was applied to gather mobile emission estimates for air quality conformity for OKI 2050 Plan amendments. OKI performed travel demand and traffic forecasts for certified traffic and other transportation planning studies for the Ohio Department of Transportation, Kentucky Transportation Cabinet, and other local stakeholders, including:
- I-75 Thru the Valley project certified traffic study (PID 113687).
- Millikin Way Interchange (IR75) feasibility study (PID 113647).
- Kings Island Drive Extension traffic study.
- SR 63 corridor study in Warren County between Union Road and east of SR 741 intersection (PID 112121).
- US 52 in the Village of New Richmond traffic study (PID 114042).
EPA’s Motor Vehicle Emission Simulator (MOVES) is a state-of-the-science emission modeling system that estimates emissions for mobile sources. In 2021, OKI’s Activity-Based Travel Demand Model was integrated with EPA’s MOVES3 software.
OKI applied the integrated model to generate mobile source emission estimates for the re-designation of the Greater Cincinnati area to attainment of the 2015 8-hour ozone, National Ambient Air Quality Standard.
Other OKI Annual Report Highlights
OKI Continues Improving Public Participation, Community Outreach
OKI seeks new ways to engage the region through public meetings, workshops, surveys, social media, and other forums. For example, many of our events have moved online to include hybrid and virtual options.
OKI Aids Clean Air, RideShare, Bike & Pedestrian Trails
Viable bicycle and pedestrian trails, RideShare programs and clean air initiatives are critical to the health and welfare of a region. OKI continues to fund these important amenities because we know our region's 2 million residents value them as much as OKI does.
OKI’s Strategic Regional Policy Plan a Tool for Consistent Development
This plan’s policy recommendations help inform and guide local decision makers. They are based on regional trends in population change, increasing costs of public services, while incorporating environmental health and a better quality of life.
