Smart lighting systems for roads can help in saving energy. According to an IEA report, lighting is responsible for 199% of the global elecmaty usage and around 6% of the global gas emissions. Smart street lighting allows lighting to be dynamically controlled and also adaptive to ambient conditions

Assume that for a National Highway for roughly 100 km (that may include multiple crossroads) you need to design a smart street ga Assume that the traffic lights are separated by a distance of 100 m from each other. The lighting schedule and the lighting intensity controlled remotely. Custom lighting configurations can be set for different days such as foggy day, rainy day hot summers etc.

These systems are also equipped with sensors that can sense ambient light conditions and based on ambient light conditions can also be varied.

The smart street lighting system will decide on the lighting schedule and light intensity based on the type of environmental condition. The GUI at the remote-control point will always display the current status of each street light (on-off and Intensity) is shown in The user can then click on individual street light and turn it on-off or vary the intensity. The system may also override user input it firs that the ambient lighting conditions are such that the lighting in the area is very poor, or if the user turns on lights where none are required

For the above system, answer the following

(a) Give the detailed specifications of the system.

(b) Draw a complete deployment diagram-showing where the end devices are to be placed, how are they are mounted placed

(c) What are the requirements and specifications of each end device?

(d) Are the end devices connected to each other? How do they connect to the internet?

(e) What are the various requirements of the communication systems?

(f) How will these end devices be powered?
