TPIMS aims to connect truck drivers with available parking to enhance safety and reduce the time drivers spend searching for a place to rest.
Iowa, Indiana, Kansas, Kentucky, Michigan, Minnesota, Ohio and Wisconsin are participating in the program, using the federal grant supplemented with $3.7 million in state contributions.
Iowa has received nearly $3.4 million in the federal funds and will chip in about $500,000 in state dollars.
Participating states currently are in the hardware development phase of the project, with self-testing and system calibration taking place this fall, Mescher said.
This January, all state systems — which work independently of each other — will go live. They all are set to operate for three years and then be evaluated.
