Singapore as a test bed next-generation congestion management systems

September 18, 2012 // By Julien Happich
NXP Semiconductors has begun testing a next-generation congestion management system in Singapore.

Cars equipped with NXP's 3.5G telematics solution ATOP (automotive telematics on-board unit platform) are currently piloting this urban modern mobility solution. Singapore’s world-class infrastructure is the ideal test bed for intelligent traffic solutions as it faces the mobility challenges of today’s global megacities and aims to reduce pollution and congestion. During the Singapore trial, cars equipped with ATOP - a module allowing for cost-efficient and flexible integration into automotive electronics - will wirelessly collect real-time traffic data via 3.5G mobile broadband.

This will not only test the congestion management system, but also secure payment, road-side assistance and paperless parking. ATOP’s industry-standard, ARM7-based automotive microcontroller provides a broad range of interfaces for easy in-car integration, including CAN and USB, multiple serial inter-processor buses and A/D and D/A converters and analog in & outputs for a audio signals. The ATOP module is the core of an On Board Unit (OBU). It contains a GPS receiver that collects, with optimal privacy, real-time data such as the vehicle’s exact location, and wirelessly feeds it to a back office. This allows service centers to calculate the fastest and most cost-effective route or advise drivers to choose the best means of transportation. The NXP technology can also wirelessly communicate with other cars and traffic signs to warn drivers of dangers ahead and advise on optimum speed.

3.5G communication has the bandwidth to accommodate congestion management schemes as well as other services to improve the traffic flow and road safety. In a second step, these can be complemented with car-to-car and car-to-infrastructure communication functionality. Such comprehensive mobility concepts will allow people in global megacities such as Singapore to optimally use and combine all means of transportation - including public transport, taxi, individual transport means and car sharing. A secure element is another key feature within this communication system. Financial-grade smart card technology allows for convenient and secure payment, regardless if public or individual transport.
