FAQ - Pros and Cons of Traffic Signals

While many people realize that traffic signals can reduce the number of angle collisions at an intersection, few realize that signals can also cause an increase in other types of accidents. For example, it has been well documented that other types of accidents, notably rear-end collisions, usually increase when a signal is installed.

Normally, traffic engineers are willing to trade off an increase in rear-end collisions for a decrease in the more severe angle accidents; however, when there is no angle accident problem at an intersection, there is nothing to trade off, and the installation of traffic signals can actually cause a deterioration in the overall safety at the intersection. Traffic signals should not be considered a "cure-all" for traffic congestion, and the primary goal of all traffic engineers is to attain the safest and most efficient traffic flow feasible.

In addition to an increase in accident frequency, unjustified traffic signals can also cause excessive delays, disobedience of signals and diversion of traffic to inadequate alternate routes.

Traffic signals are much more costly than is commonly realized, even though they represent a sound public investment when justified. A modern signal can cost taxpayers between $80,000 and $100,000 to install, depending on the complexity of the intersection and the characteristics of the traffic using it. On top of this, there is the perpetual cost of the electrical power consumed in operating a signalized intersection 24 hours a day. This cost now averages about $1,400 per year.

Traffic Lights are an integral part of urban infrastructure, so everyone can drive safer. Traffic lights are just part of everyday life, but what happens when there is construction, road repairs, emergency, or any other temporary project taking place that effect the normal flow of traffic.

1)     The need for Portable Traffic Lights

There can be many situations where the traditional lights cannot be used. There could be roadworks, accidents, emergency situations, construction, or other projects. The PTL2 can offer great convenience and is a great option in these cases.

The mobile nature of portable traffic lights and the easy set up makes then a convenient way to manage traffic. Less training and preparation are involved than hiring a stand in, meaning more time getting the job done. The design of each unit is to provide the best benefit from the least amount of equipment.

2)     Versatile

These units make controlling traffic a breeze. You may use a traffic light to control traffic flow in busy locations like schools or construction sites.

3)     Easy Operation

Designed to be user-friendly, making them accessible to both our experts at ETC, and non-experts. Most models feature a manual and control panels that allow for easy programming and adjustment of light sequences.

4)     Increased Safety

The main reason to use portable traffic lights is that they remove the need for need for in-person traffic controllers known as crossing guard. By removing the human factor, the chances of any individuals working on site or nearby pedestrians being harmed is reduced.

They offer clear and signals to drivers, reducing the chances of confusion or accidents. Because our units run from solar power, it is ensured they remain operational during interrupted circumstances such as power outages or bad weather.

5)     Cost Effective

Investing in these units can save you a great deal of money in the long run. The cost savings are apparent when you consider the labour costs of a traffic controller and the risk that arise when using a person rather than a machine.

6)     Eco-Friendly

Here at ETC, we pride ourselves on being 100% eco-friendly. All our products are completely run on solar energy. The way of the future.

7)     Increased Efficiency

Depending on the projects, the units can be operated by one person. Instead of having multiple workers to stand with &#;stop-and-go&#; signs to direct traffic, those workers can be used elsewhere. As a result, having this units have the potential to boost output and decrease the duration the duration of construction.

This can also be effective in high-traffic areas or when dealing with complicated traffic patterns e.g., intersections.
