Challenge / Goal

Ambulances arriving at accidents earlier save lives. The same applies to fire trucks and police cars. However, on their route, these vehicles have to cross traffic lights that do not know the vehicle is in a hurry. Although driving through red light is allowed for emergency vehicles, it takes time and is dangerous. Therefore, the Government of Yucatan in Mexico has chosen to implement innovative C-ITS technology, giving green light at all intersections an emergency vehicle passes on their way to and from an incident.


Peek Traffic provided cooperative technology based on communication between road users and intelligent infrastructure. The anonymized real-time GPS data of Emergency vehicles continuously send their anonymized  GPS and speed data, via the mobile network, to a local fleet management database. This data is processed in the FlowSense Cloud and mapped on a digital duplication of the infrastructure of the city. When nearing an intersection, the green is dynamically adjusted by the FlowSense cloud, depending on the needs of the emergency vehicle. This data is sent to the on-street traffic light controller. Priority requests at traffic light controllers are processed by the control algorithm and absolute priority for the emergency vehicle is provided in time.
