Kirkland-based INRIX said today that it has launched a new, mobile traffic app, which includes features aimed at helping drivers avoid paying too much for gas. The firm said that its new INRIX Traffic app for Android includes a feature which lets users locate the closest, cheapest gas from over 100,000 gas stations locations nationwide. INRIX did not say where it is sourcing the gas prices from. The app also provides navigation and mapping help and other traffic information.
