Every day, more than 200,000 people migrate to cities forcing urban centres, globally, to go vertical. Cities are faced with the task of making urban environments smarter. But at the heart of smart cities are intelligent buildings.
While smart equipment is required for a building to be intelligent, only having excellent lifts, escalators and related solutions is not enough. Advanced technology has to be integrated with different building systems.
“The more people we have in buildings, the more intelligent transportation solutions are needed,” says Dr. Marja-Liisa Siikonen, Director, People Flow Planning.
Dr. Marja-Liisa Siikonen leads an international network of traffic planning specialists at KONE, who help customers plan and implement the best possible People Flow® well before a building’s blueprints exist.
LAYING THE GROUNDWORK
For instance, in the world’s second-third-tallest building, the Makkah Clock Royal Tower Hotel in Mecca, Saudi Arabia, the building planning stage continued for more than seven years, and Siikonen’s team provided hundreds of traffic analysis revisions to the client.
Since the venue is next door to Masjid al-Haram, the world’s largest mosque (which accommodates up to two million people), the goal of the customer was to ensure up to 75,000 people exit all seven buildings through the podium in an organised and timely manner every prayer time, five times a day.
In addition to a thorough study of optimum people flow solutions (resulting in more than 320 units of escalators and lifts in the podium and the towers), KONE implemented special group control software with artificial intelligence capabilities to learn and track passenger traffic patterns in order to optimise people flow.
A combination of KONE’s people flow planning solutions and technological innovations have been also used in many recent multipurpose projects (buildings that house a mix of residential and retail with hotel and office space) around the world. The Leadenhall Building, the latest iconic addition to London’s skyline, is a fine example.
“For multipurpose buildings, KONE’s intelligent control systems such as the KONE Polaris destination control system (DCS) allows lifts to prioritise service to certain parts of the building at peak times,” says Siikonen. So, in a mixed-use building (housing a hotel and an office), while majority of hotel guests will likely be away during the daytime, majority of office workers will be present during the day and away at night.
CODING FOR IMPROVED SERVICES
The DCS allocation algorithm searches for the optimum routes for the lifts to serve a destination call. The algorithm is able to identify the best routes for the lifts within milliseconds. Optimal call allocation decisions guarantee short passenger waiting and journey times by using measured stopping times and lift flight times. The DCS system also forecasts individual passenger journeys.
“When comparing a conventional lift system to a DCS, it could be said that the conventional system is like a bus and DCS is like a dial-a-ride taxi that takes you to your destination floor in the fastest way without unnecessary stops at other floors,” says Siikonen - a smooth ride to the top in a vertical urban reality.
