Smart Bus Solutions

Today, over 50% of the world's population lives in urban areas. The portion is estimated to reach nearly 70% by 2050, making transportation one of the toughest challenges for cities around the globe. With the advancement of automotive IoT and 5G communication technologies, ITS (Intelligent Transportation Systems) is being implemented in many cities to improve traffic congestion, safety, and cost-effectiveness.

An ITS system is capable of making critical and timely traffic decisions from management centers or roadside infrastructure through networks of sensors, intelligent embedded solutions, distributed computing ability, and wireless connection capabilities. In other words, an ITS uses new and emerging technologies to make moving around a city more convenient, more cost-effective (for both the city and the individual), and safer.

 As environmental awareness rises, more and more local governments have set goals to raise the proportion of people using public transport. Many have embraced and developed intelligent public transportation systems to increase efficiency and safety with lower operating costs. Among all, smart buses are considered one of the most welcomed choices for their lower infrastructure costs and faster deployment.

In addition, with video analytics ability and edge AI imbued, it becomes the key to automated services such as total passenger control and AFC (Automated Fare Collection). Meanwhile, smart buses interconnect with the surroundings and the control center through GNSS and IoT technologies. Hence the operator can conduct fleet management and provide better PIS (Passenger Information System) service that delivers essential real-time information to passengers. Furthermore, as smart buses collect traffic data continuously and collaboratively, operators can gain more insights to improve service, enhance utility efficiency, and rearrange routes or timetables when necessary.  

Challenges and Solutions

Although high temperatures, shock, and vibrations can cause damage and severely reduce the lifespan of electronic devices, these factors are common for in-vehicle systems. All Cervoz in-vehicle products are compliant with ISO-16750-3 standards, ensuring that they can withstand shock and vibration for a continuous 24 hours, and survive a 100cm-6-face drop test. These stress tests simulate the actual conditions of vehicles in an outdoor operation. Our optional Anti-Vibration Fill also can help secure PCB and main chips in their place and prevent solder joints from coming loose. All Cervoz flash storage products come with wide temperature versions that can operate stably between -40˚C to 85˚C. In addition, our in-house developed conformal coating is optional compliant to all our embedded products, protecting the storage from dust and humidity in vehicles.

With the emergence of electric transportation, power supply instability and outages may pose problems for owners and operators. Cervoz Powerguard is our firmware-and-hardware integrated power loss protection technology. Powerguard provides additional power to the memory during an unexpected power outage to complete the current flash write operation and protect data integrity and the firmware. Meanwhile, its under-voltage protection feature prevents recording erroneous and incomplete data, which may damage data validity and the device during a power outage.
