Vehicle Traffic Driven Camera Placement for Better Metropolis Security Surveillance

Abstract--Security surveillance is one of the most important issues in smart cities, especially in an era of terrorism. Deploying a number of (video) cameras is a common surveillance approach. Given the never-ending power offered by vehicles to metropolises, exploiting vehicle traffic to design camera placement strategies could potentially facilitate security surveillance. This article constitutes the first effort toward building the linkage between vehicle traffic and security surveillance, which is a critical problem for smart cities. We expect our study could influence the decision making of surveillance camera placement, and foster more research of principled ways of security surveillance beneficial to our physical-world life. Security surveillance is one of the most important issues in smart cities. Due to the continuous growth of cities in size and complexity, keeping cities safe becomes critical to attracting skilled people and investments necessary for economic growth and development. Compounded by terrorism, cities, especially metropolises, have to carefully conduct security surveillance. To fight against the adversary, deploying a number of (video) cameras is a common surveillance approach, which has gained prominence in policy proposals on combating terrorism [1].
