STEP 1. Background
TheHKSAR government hopes to position Hong Kong as an international R&D hub through a number of Smart City initiatives that will strengthen its competitiveness in the global arena.
Kowloon East was assigned as the pilot area for Smart City deployment and testing, with major events in the area taken as sample projects.
STEP 2. Business Challenge
Hong Kong has a mass population in relation to its geographical space, and this is especially evident where large-scale public events are held.
With roads typically closed off to traffic and limited transportation to such events, it is crucial to crowd manage efficiently to optimise operations without compromising the safety and security of the public at large.
This requires a lot of manpower from both the event organisers and public service agents, and is not always an ideal solution. Thus, it was time to find a more sustainable and efficient solution to crowd management and public safety.
We kick-started the Smart City “Proof of Concept” trial in 2017 at the Streetathon Marathon held in Kowloon East that involved an estimated 15,000 participants.
STEP 3. The Solution
IoT devices like CCTV cameras and sensors were installed at key peak areas along the race route to track people density and traffic flow. The videos captured from these detectors are instantly transmitted through wireless communications to a secure cloud server.
Advanced video analytics in the cloud server breaks down these data into useful real-time information like transportation wait time based on people density, and optimal alternative routes for crowd dispersal.
The analysed real-time data is then communicated to key stakeholders through an API, internal mobile app, or on display panels in the control centre. This enhances management and operational efficiency, without the need to wait hours for such data to come through.
Display of these real-time traffic information were also shared on large LED screens at strategic locations along the event’s arena to the public at large for participants and visitors to have a more informed overview of the venue.
STEP 4. The Results
Participants receive real-time data on congestion status of the venue and queue time for transportation and as a result, can better plan for their travels and avoid overcrowding.
Organisers and public service agents alike are informed in real-time on crowd situations and traffic conditions which allow for better operations and manpower allocation.
Safety and security better monitored in real-time; CCTVs and sensors alike are able to cover a wider distance as compared to manpower monitoring.
Increase employee productivity and optimise operational efficiency with the instant communication of crowd data.
