What is your 1 biggest pet peeve regardin driving habits of others?
Older, orginal lights were operated solely by a timer. The timer was adusted manually according to traffic surveys.Newer lights have a wire that is placed in a groove in the pavement at or just before the stop lines on the pavement. That tells the system when a car has stopped and the system will begin to operate a timer that will activate the lights to turn red and stop traffic coming from the other direction.
What is the point of speed camera detectors?
Most stoplights in cities and large towns have sensors under the road that sense how many cars are in one side of an intersection vs. how many cars are on another side. But most stop lights in small towns are just timed to have one side green for so long and then the other side green for a certain amount of time.can u stop a child from turning of the safe search option?
there are sensors in the road so when you stop at the lights the sensor detects that there is a car there and it makes the lihts change after a certain amouhnt of time, basically it will stay green for a certain amount of time depending on the time that the sensors in th road detect other cars behind you and other cars at other places waitning to go at the lights.Most Light systems have a pressure sensor in each lane to tell the signal when a car is present. They also tell them which lane has more cars or the heaviest traffic so the light can decide which lane to keep green longest. This is also the way that the light can tell if it needs to turn the green arrow on for the turn lane or if the lane is empty. Most lights also have a maximum and minimum time setting for a light cycle to complete.
What should be done about very elderly drivers?
Older systems often are strictly on timers.
Newer systems use optical devices to monitor lanes. They also include cameras to catch light runners, tied in with afore mentioned optical sensors.
What happens when you drive a car at full speed and then pop it in reverse?
it's work by a timer just thatwho has the right of way, a person making a u turn at a green light or a right turn at red light?
What, Alien said.Anyone heard anymore news on the 2 year mot, I believe a lot of Europe already have?
i was told lights are 3 mins longand then it changes yellow, red or green
Most locations detect the prescence of vehicles with detector loops. These loops are put into the pavement at intersection approaches and detect vehicles. This then triggers the light to go into green time. Another technology that is currently replacing the pavement loops is video vehicle detection cameras (VIVDS). These cameras mounted on the mast arms can detect when a vehicle approaches the intersection. Then the signal knows that that approach needs green time. Most locations in urban areas run on some type of detection. This allows the signal to operate based on the demand that is present at that particular time. This is the most efficient way to operate a signalized intersection. Other locations have fixed timing programs in them that may change at different times of day, such as peak hour.
