As in most of China’s metropolitan centers, Shenyang, the capitol of Liaoning province in the country’s northeast, smog is an all-toocommon occurrence. Picture Courtesy: Siemens

A new software solution is helping cities remedy the growing problem of air pollution and the associated lack of compliance with emission-control thresholds. Siemens presented City Air Management (CyAM) at the World Cities Summit in Singapore. CyAM is a cloud-based software suite with a dashboard that displays real-time information on the air quality detected by sensors across a city and predicts values for the upcoming three to five days. These air-quality forecasts are prepared with the aid of algorithms that tap into an artificial neural network and draw on historical and current data on air quality as well as weather and traffic patterns. Mayors and other decision makers can then use this data and a combination of potential solution measures to derive concrete recommendations for action and define measures that help reduce concentrations of nitrogen oxides and atmospheric particulate matter.

CyAM can use the data acquired by sensors to recommend a selection of actions chosen from a set of 17 measures that can be implemented at short notice in order to improve air quality. Examples of such measures include establishing low-emission zones, reducing speed limits and offering local public transportation services at no charge for a limited period. Cities can subsequently integrate insights gained from these actions into their medium- and long-term strategy planning. CyAM is based on MindSphere, Siemens’ Cloud-based, open operating system for the Internet of Things.

Siemens signed a Memorandum of Understanding (MOU) with Sino-Singapore Guangzhou Knowledge City Investment and Development Co., Ltd. (GKC Co) and Ascendas-Singbridge to kick start the CyAM solution, through a joint development of the Green City Digital Platform in Sino-Singapore Guangzhou Knowledge City (SSGKC).

Both GKC Co and Siemens will also be exploring the establishment of The Siemens Green City Digital Exhibition Center in Ascendas OneHub GKC, an integrated business park within SSGKC. The first of its kind in Asia Pacific, the Siemens Green City Digital Exhibition Center will provide real-time air quality monitoring on a short-term and mid to long-term basis, as well as assessment, impact prediction, and recommending of technology measures.
