Why We Need Speed Limits Scepticism about current British speed limit policy does not mean that we should dispense with limits altogether It may be thought that since I have created a website with details of speed camera locations, limit reductions and "great driving roads" where people might drive the odd mph or two above the speed limit, I'm not really in favour of speed limits. A properly trained driver should be able to judge an appropriate speed without the help of a number painted on a tin sign.
In Pennsylvania, only 65 mph. In Wisconsin, interstate speed limits recently increased from 65 mph to 70 mph. Many highways across Minnesota have increased from 55 mph to 60 mph. Why are there so many different speed limits?
Why do speed limits continue to rise? Speed limits are going up in areas of Wisconsin and Minnesota.
Pictured here, an I on-ramp near Woodbury, Minnesota. Road classification matters First, and most logically affecting a speed limit on any given road, is how that road is classified. While actual roadway classifications vary by state, they can be reduced to three general types: Arterial have highest speeds and fewest access points example: Collector are balanced for higher speeds but more access points example: Local have low speeds, but high access example: The differences among these classifications speed as inversely proportionate to the amount of access points explain why different speed limits are necessary.
Roads with fewer intersections — with fewer travelers moving perpendicular to one another — can generally sustain higher maximum speeds and still be considered safe. Roads with more intersections, and often more bikers and pedestrians, have more people moving at different speeds in different directions, and need lower maximum speeds.
But while speed limit decreases and traffic calming measures are being implemented on many local roads, interstate speeds have increased, and continue to increase, in many states across the country. Why are these two occurrences, seemingly at odds with one another, happening at the same time?
The answer is the same for each. One road, many limits: With recent improvements intended to increase safety, Tower Avenue in downtown Superior, Wisconsin, is actually part of the longest highway in the state of Wisconsin, Highway 35, which has varying speed limits depending on number of access points and other criteria.
Here are four commonly held, but inaccurate statements about speed limits: Lowering a posted speed limit will slow down traffic.
Lowering a posted speed limit will increase safety and decrease the number of crashes. Raising the posted speed limit increases traffic speed.
Drivers will always travel at 5 mph over the posted speed limit. There is no guarantee that a speed limit will have any effect on driving behaviors.
The fact is, when driving, most motorists choose a speed in which they personally feel both comfortable and safe. As cars have evolved to go faster and be safer, so too has the inclination for drivers to increase speeds on open roads and rural interstates. Simply, a speed limit sign should not dictate speed.
It should reflect how drivers are actually behaving on the road. When you want drivers to slow down, you change the road through traffic calming measures like speed bumps or even design narrower roads, both of which make speedy drivers less comfortable.
How speed limits change How do speed limits change? In most cases, speed changes, whether local or state, are the result of a study. A public agency conducts a spot speed study also known as a speed zoning study to document individual vehicle speeds along a specific road. The speed data is then plotted on a chart that looks like the one pictured below at left.
From this data, we want to know how fast the majority of motorists are actually driving. Specifically, how fast 85 percent of them are going.
The results of a spot speed study left are used to determine how fast 85 percent of motorists are driving right. Because it is the safest. Why is the 85th percentile of speed safest? Imagine a car moving dangerously slow in the left lane, or a car weaving through traffic at extremely high speeds.
These vehicles are unpredictable and dangerous. This is not solely due to their speed, because fast and slow are relative, but because of their speed in relation to other drivers.
As you can see in the graph below, safety decreases significantly as drivers deviate from the prevailing speed.Speeding is Bad essaysIn American society today, there are certain laws designed to protect all citizens. One such law is the speed limit law.
Despite the many variations of the law found throughout the country, it is essentially the same everywhere.
