Public invited to check out new traffic model

January 28, 2019

A long-awaited traffic model will be on display at public information sessions Wednesday.

A more technical presentation will be held from 10 a.m. to noon, followed by a broader presentation from 5 to 7 p.m. Both sessions will take place in Teton County commissioners’ chambers at 200 S. Willow St.

Massachusetts consultants who compiled the model are in town to demonstrate it, said county engineering manager Amy Ramage.

“They’re going to talk about the background information that went into the model and what the model can and can’t do,” Ramage said, “and then they’re going to show a couple test-case scenarios.”

In September 2017 the town of Jackson, Teton County and the Wyoming Department of Transportation paid consultants at Cambridge Systematics $150,000 to create a travel demand modeling system. It’s meant to be used as a tool in the decision-making process as traffic projects are proposed and considered.

The data put into the system includes WYDOT traffic counts, lodging inventories, employment and housing studies, and “big data” — aggregated, anonymized information purchased from GPS and cellphone companies.

The model is expected to be able to test the impacts of changes to the local transportation network like new roads, new START routes or new developments.

The delivery of the project was delayed substantially. It was originally expected to be completed last spring, but Ramage said it took longer for county staff to pull together data for the model. However, it remains on budget, she said.
