Cameras constantly monitor roads, vehicles, and movement patterns, this data could be misused if not properly regulated. +- IoT systems are connected to networks, so if hacked, attackers could disrupt traffic lights and cause accidents or chaos. +- Implementation cost is high, since each intersection requires sensors, cameras, as well as infrastructure upgrades +- Failures (e.g., sensor errors or outages) could worsen traffic instead of improving it. + + +Source:https://nlt-group.com/nlt-group-pilots-an-smart-traffic-system-in-hcmc
