(a) Identify two possible ways that the road sensors can detect the passing of
a vehicle. [2 marks]
One way that the road sensors can detect the passing of a vehicle is the video camera on the traffic light, it can take a video of the car passing and record the data in it's video logs and database. Another way they can detect a passing vehicle is through specific monitoring devices that record speed, for example they have radar guns that measure speed and can show how many cars are passing and at which speed.

b)Two ways it could decrease travel journey times is by using sensors to show the speed of people and on major highways because if they did that than less people would use the road in fear of being billed a fine or caught for speeding and by using alternative roads they would not be stuck in traffic which would lead to less people on certain roads and reduce journey time. Another way they can decrease travel journey time is by changing the speed limit and by doing that people would travel at different rates and there would be less congestion on the road.

(c) Explain how the images from the digital speed cameras can be used to send
penalty notices to speeding drivers automatically. [4 marks]
The images from the digital speed cameras can be put into a database and then identify the driver through their license plate number because the database would include all of the license plates with the information of the driver. The penalty would be sent directly to the driver through the mail because the cameras could print out the information of the driver and how fast they were going through hardware like a printer. Another way is by faxing the information and speed from the camera to the user in their listed place of work or business.

(d) This could be abused by authorities because they would not have to do their job any longer because the cameras would do it for them. They would not have to reprimand speeding criminals because it would be done through the the cameras and sent automatically to the driver. The possibilities of this are that the authorities would no longer have initiative to do their job and many more people would receive fines for speeding because they would virtually not be able to speed without getting caught due to these cameras. The advantages of these cameras for the authorities however is that they will be able to catch more speeders than they would if they did not use the cameras. It would cost a lot less for the state because they would not have to hire as many authorities specifically highway patrol officers because the cameras would catch whoever was speeding. Another advantage would be that the authorities can catch people that abuse their car and speed much too often and put others in danger, by doing this it would take more people off of the street and keep things safer. However the disadvantages of this are that the police officers would become lazy in their duties because they would not have to do as much, and it would lead to problems politically because people do not have as much freedom. They are taken away from their freedom because they are constantly being surveyed which leaves them with no way to escape the authorities and ultimately the government as a whole. The disadvantages outweigh the advantages because if this were to happen it would cause havoc in the the world because people would be raped of their freedom and many rebellions and revolts would be the result. I believe the disadvantages outweigh the advantages because I believe it is important to have our freedom...
