![]() This is no glossy, feel-good, escapist cinema that has actors dressed in designer outfits and breaking into songs in the Swiss Alps. Actually, you need to have a strong stomach to absorb the characters depicted in TRAFFIC SIGNAL. A world we see every single day at the traffic signals, but forget all about it the moment the signal light turns green.Ī flourishing 'industry' exists at the signals and those who engineer and run the 'empire' include gangsters and politicians. Madhur Bhandarkar's new outing TRAFFIC SIGNAL introduces us to a world we thought never existed. CORPORATE was about wars fought inside the Board Rooms. PAGE 3 exposed the glitzy lives of the glitterati and chatterati. In particular, in a live test the experts very easily and very quickly gained the control of the system of at least 100 traffic signals, in an unnamed city in the Michigan, from a single point of access, a local road agency.Īs explained by the experts the use of wireless radio transmissions (a combination of 5.8GHz and 900MHz radio signals) is very common for traffic light systems, this choice allows to reduce the costs of installation and maintenance of the networks.ĬHANDNI BAR peeped into the lives of bar dancers. ![]() ![]() Vehicle detection systems are composed of magnetic sensors hidden in the roadways that collect information about the traffic flow and wirelessly transmit it, through the proprietary protocol Sensys NanoPower Protocol, to nearby access points and repeaters, which then sent the data to traffic signal controllers. However, these improvements have raised serious questions in term of security of the overall architectures, the components of traffic light systems are today remotely accessible and wireless interconnected, with serious repercussions in term of security. Wireless networking represented the optimal choice to reduce the interconnection cost and quickly implement an interconnected network of traffic light control systems. We often see movie scenes in which hackers are able to hack systems for the control of traffic lights, with catastrophic consequences, unfortunately, we must be conscious that threat actors are really able these complex infrastructures causing serious problems.Ĭoordinated traffic signal systems provide great benefits in term of wasted time, environmental impact and public safety, but for their interconnection, public administration have to spend a great effort to ensure an efficient interconnection on a metropolitan geographic distribution.
