2045 Traffic Forecast Update (3/13/24)
Every five years, the Regional Planning Organization, the Capital Area Metropolitan Planning Organization (CAMPO) for Central Texas, updates the Regional Transportation Plan (RTP) to better reflect the population and employment demographics, travel patterns, and regional projects. Per the National Environmental Policy Act (NEPA) requirements, every Environmental Assessment must include a traffic study performed to Federal Standards based on the most recent RTP.
The MoPac South Environmental Study has been updated with the most recent data provided in the CAMPO 2045 Travel Demand Model. The new Corridor Model has been utilized to complete the traffic evaluation of reasonable alternatives presented in Open House #3 and the Operational Configuration Options presented in Open House #4 and #5.
Click below to learn about the changes to the Corridor Model and see the results of the build alternatives traffic evaluation.

VISSIM Models
VISSIM modeling allows us to visualize how changes in the roadway network could impact traffic within the network. Watch the video below to learn more about how the express lane(s) operational configuration options described above could impact travel times and traffic patterns on MoPac, and downtown Austin.
Downtown Traffic Impacts
The Mobility Authority contacted the University of Texas Center for Transportation Research (CTR) to provide data that would help us understand how the addition of express lanes on MoPac, in several of the six configurations currently being considered, could impact travel times on the street network within downtown Austin. CTR conducted an independent analysis of these impacts through a local dynamic traffic assignment, or DTA, study. Learn more about the results of this study through our video interview with Jennifer Duthie, Ph.D., Director of the Network Modeling Center at CTR.

2/17/2015 Workshop Materials for Download:
On Tuesday, February 17, 2015 a Bicycle and Pedestrian Workshop was held to inform and seek feedback on the Mobility Authority’s current and proposed investment in bicycle and pedestrian improvements. Team members from the four projects currently under study – 183 North Mobility Project, MoPac South, MoPac Intersections and the Oak Hill Parkway Project were on hand to explain the proposed improvements and record input. The event was attended by 17 individuals from 6 different organizations representing the bicycle and pedestrian community.
