Singapore has more than 300 bus lines, providing public travel service for millions of people every day. Jaguar Wave worked with Panasonic Singapore, applied mmWave wireless backhaul system to buses, stops and monitoring centers, to realize real-time bus lines blind spot monitoring.
Challenge
With a narrow land area and high population density, the urban roads in Singapore bearing great traffic flow pressures. In order to improve public traffic trip efficiency, control more road information and optimize traffic network, a new reliable real-time data backhaul path is needed.
Solution
We installed two 60GHz mmWave antenna modules which powered by solar power system at the bus stop, one aligns to vehicle travel direction and the other to the roof of building, and the camera on the stop is connected to the 60GHz mmWave antenna module；
The 60GHz mmWave module is installed in the bus, when the bus enters the signal coverage area of the 60GHz mmWave antenna module, the two devices will establish a connection automatically, and the HD monitoring video will be transmitted to the display screen of the bus in real time;
The 60GHz mmWave module on the building connecting with the 60GHz mmWave antenna module of the stop, so the HD monitoring video of the bus stop can be transmitted to the computer room in real time, which can be used for storage and AI analysis.
Results
When the bus approaching the stop, the mmWave module connects with each other, and transmits the HD video of platform to the display screen of the bus, the driver can have an overall understanding on road conditions in advance without worrying about blind spots.
The monitoring center can get the real time video data about roads, platforms and the bus through mmWave backhaul system when driving. Combined with AI system, the driving routes can be optimized to achieve efficient scheduling, and discover abnormal conditions of road or bus at the same time, which ensures driving safety.
Building mmWave wireless backhaul network is very suitable for mature bus system of Singapore to newly-built or upgrade vehicle-ground communication system because there’s no need to lay cables. The ultra-large bandwidth can carry massive data of vehicle-ground communication system, which is fast and stable. The automatic connection and upload mode provides a large amount of accurate data for AI system, that can realize driving routes optimization, vehicle scheduling, pavement maintenance reminder, and vehicle safety warning, which greatly improves the efficiency of the public transportation network.
