As New York shows, open data is the key to smart traffic solutions
Winnie Tang says Hong Kong can learn from the New York experience in addressing privacy and data security concerns, to build trust between the local government and its people as smart cities move towards open public data

Data security was yet another concern. A flaw in the data anonymisation process, which should avoid identifying individuals, enabled software developers to reidentify all 173 million entries of taxi drivers’ “hack” licence numbers, revealing which driver took each trip. Finally, after a hearing at which citizens engaged with public officials, the pickup and drop-off locations were substituted with a neighbourhood code on the portal.

The development of New York’s open data policy and its roll-out was a partnership between the agency leadership, city politicians, civic technology leaders, government oversight groups and ordinary citizens. The government continued to engage stakeholders so that the law remained relevant.
The New York experience is a good reference for Hong Kong. All sections of society should keep an open mind and be willing to share their concerns and aspirations on the issue. That’s the best way to move the city forward.
