The United States Department of Transportation (USDOT) and the Institute of Transportation Engineers (ITE) and their standards development partners (AASHTO; NEMA) have worked on Intelligent Transportation Systems (ITS) standards since the inception of the program more than 2 decades ago. ITS and CTI established technologies are being expanded upon as the need for increased security and stability measures must meet the demand of road users, and the systems implementing these standards and the ever-developing technologies utilized by road users.
