Smart Cities: Nanjing and SAP Create Intelligent Traffic System in China

Feature Article | November 17, 2016 by Paul Taylor

The City of Nanjing, once the capital of China, is one of the top 20 cities in China, with a population of just over 8 million. Traffic volume is also enormous.

There are about 10,000 taxicabs, 7,000 buses, and 1 million private cars running throughout the city road network.

To help cope with the traffic volume, Nanjing developed a next-generation smart traffic system that includes the use of sensors and radio-frequency identification (RFID) chips to generate continuous data streams about the status of transportation systems across the city.

The city makes use of SAP IoT and SAP HANA to analyze traffic movement patterns in real time. In total, more than 20 billion sensor data are generated annually in the city. This data is combined with other data such as travel behavior of individuals, fare prices, road conditions, and area accessibility. Smart traffic analytics using advanced analytical algorithms help the city to make sense of the data.

All the information flows into one digital map that gives a detailed view of current traffic conditions across the city as well as the ability to predict status and provide recommendations for planning.
