The best traffic calming options!
The increase in traffic and congestion has jeopardized road traffic safety. With so many motorists, enforcing traffic rules has become more difficult than ever. Also, the air has been polluted with noise and smoke. Hence, no stretch of road can be done without a traffic control plan.
Traffic calming techniques are still the most relevant measures for traffic control. However, there are a large number of these traffic control devices available. These vary in terms of cost, traffic count, and the type of roadway in question.
The optimal calming techniques can reduce the number or severity of accidents while protecting pedestrians. They’ll also quieten a noisy neighbourhood.
Therefore, every traffic engineer must determine and recommend the best traffic calming options.

What is traffic calming?
An uncontrolled intersection can adversely affect road safety. That is what traffic calming is about: it regulates speed control.
It creates discomfort in the driving routines of oncoming motorists. This is to slow down each of them to protect their motor vehicle. Slow traffic leads to lesser chances of collisions and, hence, fatalities.
Fewer crashes improve pedestrian safety, making the crosswalk less hazardous. But the system doesn’t just conform to pedestrians.
Every cyclist has a great chance of being injured on the road. These safety programs try to make it less unsafe for the average bicycle user and prevent crashes.
But there is a disadvantage. Traffic calming causes traffic congestion, slowing down emergency vehicles such as fire trucks. This hazard is countered by creating traffic lanes just for emergency-response vehicles.
As a result, the vehicular traffic volume on a single road is reduced along with pollution.

How important is traffic calming in the UK?
Traffic calming has existed in the UK since the 1930s. The committees in charge wanted transportation engineers to reduce noise pollution in residential areas and city streets. With time, more intelligent transportation systems were required as the population grew. Today, the situation is much worse.
A report by the UK government showed that in 2019, the country’s traffic was ten times more than what it was 70 years ago. This has risen to even higher levels after the pandemic as people avoid using public transportation.
Hence, relying on police enforcement is more expensive and requires more manpower.
Traffic calming versus traffic control signs
Transportation engineers use reflective traffic signs and markings to discourage and warn against overspeeding. These include stop signs, speed limit signs, and parking signs. They are considered to be inexpensive and primitive for speed reduction. They’ve been used on British roadways since the 1960s.
However, studies show that they become more ineffective as more of them are used. In fact, the UK is following a CAM Roadmap, and it will remove all of its regulatory signs by 2027. This will be done in favour of CAM (Connected and Automated Mobility) technology, which is more effective and cheaper.
What do traffic calming measures do?
Various traffic management techniques exist, but they all have one thing in common: they aim to create a slow zone when used. So, while traffic calming measures are used in municipalities and parking lots, property owners can also use them on their own driveways.
These measures work by either narrowing the road, raising it, or diverting its traffic. Many of them exist, but they’re divided into 4 common categories. The following are the main types of traffic calming techniques:
1) Horizontal deflections: These measures tend to swerve the flow of traffic on the horizontal plane
2) Road narrowing: This includes a variety of methods to decrease the width of the carriageway
3) Vertical deflections: They are raised sections that jolt vehicles upwards after slowing them down
4) Miscellaneous: This comprises everything else, including signage, islands, street furniture, traffic signals, and speed cameras

Ten alternatives to speed bumps
With dozens of traffic calming techniques available today, picking the right one requires great intuition. This is because the concerned transportation department needs to rely on the traffic data and the road type. They need to observe all the surroundings (like if it’s a school zone).
The results can positively or negatively affect not just traffic flow. But they’ll also influence the daily routines and driving habits of up to thousands of motorists. Out of a total of 70 calming measures, the speed breaker is widely used.
These raised sections have been deployed as ”sleeping policemen” for almost a century now. They are very effective in bringing motorists down to a low speed.
Speed bumps can be used in a series pattern to create a slow zone. But there are several other traffic-engineering alternatives to speed bumps.
The following are the 10 best ones in no particular order:

These are part of the horizontal deflection category. They’re used to swerving vehicles by creating extra turns on the road. Chicanes are very effective, and they are used along with road signs.
2. Median diverters
These are used to restrict the number of vehicles entering a street. The diverted vehicles are made to travel into separate roadways.
3. Corner radii
A corner radius, or corner radius, is an efficient calming technique for an intersection. It leads to lower speeds of vehicles entering or leaving a street. It is safer for pedestrian crossings as well.
4. Kerb extensions
Kerb or curb extensions are used to narrow a stretch of road so that drivers have to slow down. The wider footpath can be fitted with benches and trees for a more aesthetic look.
5. Bus or Bike lanes
This is when roads are narrowed, but instead of extending the kerb, lanes for bicyclists are added. These are exclusive to cyclists and are instrumental in preventing accidents. Bus lanes can also be added so that buses can travel without the fear of colliding with a motorist or a bicyclist.
6. Two-way streets
A simple one-way road with a speeding problem can be turned into a two-way street. It will have vehicles travelling in parallel, but the traffic direction will be opposite.
7. Pinch point
Pinch points also fall into the road-narrowing category. However, they only reduce the width of a small road point instead of the whole roadway. These are usually combined with crosswalks.
8. Speed tables
A speed table is another raised section with the same working principle as speed bumps in the road. But they raise the entire body of the oncoming vehicles instead of just one axle at a time. They’re safer, but they take up more space.
9. Traffic signals
Traffic lights are used everywhere to calm traffic at intersections. A red light brings traffic speed to a complete halt so that the traffic from the other roadways can pass through.
10. Speed cameras
These are digital methods and are mostly used on highways and freeways. But they can also be used on the streets and fine anyone who breaks the speed limit.
To conclude, traffic calming measures are more relevant than ever. This is due to increased road traffic over the past few decades.
Traffic calming is the key to optimising city traffic flows to reduce accidents and pollution. Its usage leads to the better implementation of traffic laws and highway safety. Various traffic calming techniques exist, but only a few are considered for usage.
The speed bump is one of those measures, but it has alternatives. These options are tried and tested to be effective for pedestrians. However, their usage depends upon the situation and the resources available.
