If the mobility demand of London could be met with 30% of the existing vehicles imaging the benefit. Easier said today for Singapore with its digital infrastructure but surely the goal for older big cities.
The integration of machine and human sensors and the involvement of citizens in creating smart cities is important. Smart cities are there for residents and visitors whether business or tourist. The human angle is important.
Parking Services, Waste Management, Leisure Centre facilities management... so much more could be delivered with less by harnessing the new big data with analytics to manage the present and future.
As always though, the technology is a means to an end and it is the wellbeing of people rather than assets that is the key priority. That's why smart citizens are the priority to be housed and served in smart cities
"A recent paper by the SMART team showed that the mobility demand of a city such as Singapore could be met with 30 per cent of its existing vehicles," says architect and smart-city researcher Carlo Ratti. And this seems to be the goal of the Singaporean government. "We don't want to increase the number of cars on our roads," says Professor Seng of the NRF. "Autonomous public transport makes more sense than autonomous private cars."
