The real meaning of traffic light in Indonesia

signal heads

The shrinking Accrual vs Deferral indicates the time remaining in that colour. A blinking green one-third-full bar means “reduce speed now”, and a blinking yellow full-bar indicates “proceed with caution”. In some cities in Mexico, the double red light is treated as a standard red signal, with the double light’s purpose being to increase the signal’s visibility as well as providing a redundant light in case one fails. In the United States and Canada, a flashing red light is the equivalent of a stop sign. The basic rules are to stop on red, slow on yellow, and go on green, but make sure you know all of the intricacies as well. Another way to learn additional rules of the road is by taking a driver’s education class through


Installation of this signal is a violation of the Vienna Convention on Road Signs and Signals.


In this comic, Randall is commenting on the confusion that can be caused by having too many lights with multiple rules attached by creating an exaggerated example. Because of Steven Sweat, my medical support was taken care of. Steven is not only an excellent personal injury lawyer, providing the best legal advice, but also a professional lawyer who goes beyond his call of duty just to help his clients!

Computerised systems are normally actuated, i.e. controlled by loop detectors or other sensors on junction approaches. Area-wide coordination can allow green wave systems to be set up for vehicles or cycle tracks. Smart traffic light systems combine traditional actuation, a wider array of sensors and artificial intellegence to further improve performance of signal systems.

The third-from-left light has red and yellow, and later all three lights come on at the same time, then all three lights go yellow, and then reverse with green at top and red at bottom. In this strip, the right light has a sign indicating that the light and the right lane are for left turners, while the 3rd-from-left is a straight or right turn lane and the 2nd from left is right turn only. In normal course, right turns would be permitted from the right lane and left turns from the left lanes.

  • Intelight Inc. manufactures a programmable traffic signal that uses a software-controlled LED array and electronics to steer the light beam toward the desired approach.
  • UK engineers have innovated on this design through the Cycle Optimised Protected Signals junction, e.g. in Manchester.
  • Sometimes pedestrians are not aware of their responsibilities at traffic and pedestrian signals.
  • I could try making my own from scratch, of course, but for the time being, the “green” ends justify the “red” means.
  • In Japan, a green arrow with the circular green is never shown.
  • If you were involved in a red light running accident, you deserve help to get back on your feet.

The system in this comic would have turning traffic crossing each other, as well as the straight-ahead traffic and would cause chaos . The left-most light on the post has a sign indicating that left, right and straight travel are all prohibited, which is even more confusing. The three arrows LED traffic lights are energy-saving and are guaranteed to last long. The number of fatal crashes caused by red light running is 21% lower at intersections equipped with red light cameras compared to those without.

Railroad Crossing Signals

These are used because they are safer, cause less delay, and are more flexible. Flashing amber arrows will normally be located below the solid amber. The only thing that you have to think about when you see green is to keep on going. As always, just pay attention when proceeding through an intersection just in case someoneruns a red light or makes a right turn on red. Do not stop your vehicle on a railroad track, regardless of whether a train appears to be coming.

  • It serves the same purpose as the vertical Texan configuration, and mainly appears on boulevards with multiple lanes of traffic where a left turn may become catastrophic due to visibility.
  • This class will teach you how to be a safe driver in a fun way that is entirely online.
  • Even if you have a lot of driving experience, you may still come across some road signs that you don’t know.
  • At some intersections in Quebec, the yellow and red lights will appear together to indicate that the light is about to change to red.

You must stop if it is safe to do so.” In an effort to encourage safe driving, I think the driver guide overstepped a bit. As a recommendation, it’s solid advice, but as a requirement it exceeds the requirements of our state law. In the United Kingdom, 12-inch lights were implemented only with Mellor Design Signal heads designed by David Mellor.

Flashing amber/yellow

But transportation engineers at North Carolina State University are now proposing a “white light,” which would enable autonomous vehicles to help control traffic flow – and let human drivers know what’s going on. In computational simulations, the new approach significantly improves travel time through intersections and reduces fuel consumption. A World Economic Forum study found that signalised junctions are linked to higher rates of localised air pollution. Drivers accelerate and stop frequently at lights and as such peak particle concentration can be around 29 times higher than during free-flow conditions. The WEF recommends that traffic authorities synchronise traffic signals, consider alternative traffic management systems and consider placing traffic lights away from residential areas, schools, and hospitals.

green lights

On rare occasions, usually due to a power outage, the traffic light may be out. This can cause chaos to ensue because people encounter this so infrequently that they have no idea what to do. Some people may pretend the light doesn’t exist and drive right through, but this isn’t correct.

Traffic direction used to require police officers to stand in busy intersections. The second-from-left light and second-from-right lights do not appear to have any quirks other than changing phases in unusual patterns. There are also other rules and features that tend to be unique to different localities as noted in the Wikipedia article for Traffic-light signalling and operation. In terms of my traffic light system, I think of “unprocessed” as nothing bad added and nothing good taken away.

Special signals

In Germany, Ampelmännchen pedestrian traffic signals have come to be seen as a nostalgic sign for the former German Democratic Republic.In Germany, the fine for crossing a red light if caught is as of 2019 between €5 and €10. A ramp meter or metering light is a device, usually a basic traffic light or a two-phase light, that regulates the flow of traffic entering freeways according to current traffic conditions. They are intended to reduce congestion on the freeway in two ways. One is to ensure that the total flow entering the freeway does not exceed the capacity at a downstream bottleneck. A second is to break up platoons of vehicles entering freeways, ensuring that traffic can merge more easily.

Sometimes pedestrians are not aware of their responsibilities at traffic and pedestrian signals. A white steady, two-way left-turn arrow over a lane means you may only turn left, if you are in that lane, but the lane is shared by left-turning drivers approaching from the opposite direction. The researchers first introduced a “white phase” traffic intersection conceptin 2020. On a more technical side, the green light isn’t fully green. It often contains blue bulbs to help those with colorblindness.

A large portion of drivers (42.7%) admitted to driving through a stoplight that has just turned red when they could have stopped safely in the past 30 days. GREEN—A green light means GO, but you must first let any vehicles, bicycles, or pedestrians remaining in the intersection get through before you move ahead. Apart from railway and industry heritage, traffic lights also follow an international standard. The Vienna Convention on Road Signs and Signals Treaty encourages countries to sign a treaty. Countries such as the United States of America and Japan haven’t signed the treaty, so slight deviations from the international standards might occur.

The answer was a third light that was coloured amber, which was the same colour used on the railroad. In 1922 traffic towers were beginning to be controlled by automatic timers. The main advantage of the use of the timer was that it saved cities money by replacing traffic officers.

While driving to work this morning I rear-ended a car at a traffic light. You can turn left ONLY if you have enough space to complete the turn before any oncoming vehicle, bicycle, or pedestrian becomes a hazard. Vehicles turning left must always yield to those going straight from the opposite direction.

Intelight Inc. manufactures a programmable traffic signal that uses a software-controlled LED array and electronics to steer the light beam toward the desired approach. It requires a connection to a laptop or smartphone with the manufacturer’s software installed. Typical applications for these signals were skewed intersections, specific multi-lane control, left-turn pocket signals, or other areas where complex traffic situations existed.
