Our engineers are on-call, around the clock and year-round, to respond to systems incidents at our contracted sites. We receive and correlate alerts, by phone or automatically using our own in-house developed Carra Event Management System(CEMS), to monitor and respond to automated event on 24-hour basis and provide on-site and remote maintenance engineering. 

Using the Carra Maintenance Management Method (CMMM), we also provide structured preventative maintenance to maximise the serviceability of a wide range of equipment such as ANPR camera technologies, tolling systems (e.g. vehicle classification) and a wide variety of traffic-related hardware and software. We also supply and install tolling equipment and systems for new builds and upgrades.
