MAXTIME cv enables agencies to broadcast SPaT, MAP, SSM and more without additional hardware in the cabinet. MAXTIME cv is built as a stand-alone embedded firmware application designed to run on ATC 5.2b or above compliant controller hardware, reducing the overall hardware cost of the CV deployment.

MAXTIME cv communicates directly with the DSRC radio and signal firmware using published federal standards, including the latest J2735_201603 standard. To generate the SPaT and SSM message based on the current signal timing and operation, MAXTIME CV communicates directly with the signal firmware utilizing NTCIP 1201, 1202 and 1211 message sets.
