The project objective is to use mobile observations and Pikalert® outputs to forecast travel times on I-70, including weather impacts.

The purpose of this multipart project is to use connected vehicle technology along with Pikalert to produce forecasts of travel times along I-70, allowing end-users to make smart travel decisions on when and where to travel during weather impacts.

In part 1 of this project, NCAR will set up the Pikalert system over I-70 in Colorado, receiving mobile data from CDOT via WeatherCloud, and associate critical weather conditions with the CDOT database of traffic counts.

In part 2 of this project, NCAR developed a real-time travel time prediction system for the I-70 mountain corridor that includes both traffic patterns and the effects of forecast weather using machine learning.
