A Certificate Authority (CA) is an organization that issues and manages security credentials and Keys for message encryption and decryption. As part of Public Key Infrastructure (PKI), the CA provides certificates (Keys) to Issuers. The Keys are used to encrypt, sign and secure Electronic Payment Services (EPS) transactions.

Also “Variable Pricing.” Toll facility pricing that is set based on traffic demand, with higher toll rates at high-traffic periods and lower toll rates at low-traffic periods. Rates may vary by time of day, day of the week, or may vary dynamically based on current traffic conditions. Value Pricing is designed to achieve performance objectives to reduce traffic congestion and delay by shifting travel to less congested periods or different modes, encouraging high vehicle occupancy, or reducing the number of vehicular trips taken.

Connected Vehicle Program - The U.S. DOT Research and Innovative Technology Administration (RITA) \ ITS Joint Program Joint Program Office (ITS JPO) is the major sponsor of the Connected Vehicle program. Connected Vehicle focuses on localized Vehicle-to-Vehicle, Vehicle-to-Infrastructure and Vehicle-to-Device Systems (V2X) to support safety, mobility and environmental applications using vehicle Dedicated Short Range Communications (DSRC)\Wireless Access for Vehicular Environments (WAVE).  This program has support from most of the automakers and a number of state departments of transportation.
