What are Speed Tables?

Speed tables are a type of traffic calming device that is commonly used on roads to reduce vehicle speed. They are similar to speed humps but have been modified to be less disruptive to vehicle operations. Speed tables cover the full width of the roadway and have a flat top that is long enough for the entire wheelbase of a passenger car to rest on. The main purpose of speed tables is to slow down vehicle speed and improve safety for all road users. They are usually made from asphalt or rubber and are designed to be more gradual compared to speed humps. This helps to reduce the discomfort experienced by drivers and passengers while crossing over them. The design of speed tables includes a gradual incline and decline, making them less steep than speed humps. This allows vehicles to maintain a more consistent speed while crossing over the table. As a result, speed tables have been found to be more effective in reducing vehicle speed compared to speed humps. Speed tables are commonly used on residential streets, school zones, and other areas where there is a need to control vehicle speed. They have been proven to be effective in slowing down traffic and improving safety for pedestrians and cyclists. Studies have shown that speed tables can reduce vehicle speed by up to 50%, making them an important tool in traffic management.

How Do Speed Tables Work?

The design of speed tables is what makes them an effective traffic calming device. They typically have a flat top that is about 22 feet long and a gradual incline and decline on either side. This design forces drivers to slow down as they approach the table, making it difficult for them to speed over it. When a vehicle approaches a speed table, it is forced to reduce its speed due to the incline. As it reaches the flat top, the entire wheelbase of the car rests on the table, causing the vehicle to slow down even further. The decline on the other side also helps to gradually decrease the vehicle’s speed before it reaches the level road surface again. Speed tables are most effective when used in conjunction with other traffic calming measures such as speed limit signs, speed bumps, and road markings. They are also designed to accommodate emergency vehicles, allowing them to pass over the tables without difficulty. Some common locations where speed tables are used include school zones, residential areas, and busy intersections. They have been found to be particularly effective in reducing vehicle speed near schools, where there is a high volume of pedestrian traffic.  

What are Speed Humps?

Speed humps are another type of traffic calming device that is commonly used on roads. They are raised areas on the road with a curved design, unlike speed tables that have a flat top. Speed humps are shorter than speed tables and are typically placed every 250-500 feet along a road. Like speed tables, the main purpose of speed humps is to reduce vehicle speed and improve safety for all road users. However, compared to speed tables, speed humps are more disruptive to vehicle operations and can cause discomfort to drivers and passengers. While speed humps are effective in slowing down vehicle speed, they have some drawbacks. They can cause noise pollution, increase vehicle emissions, and may not be suitable for emergency vehicles. They also require more maintenance as they can wear down quickly due to frequent use by vehicles.

Comparison between Speed Tables and Speed Humps

Although speed tables and speed humps serve a similar purpose, there are some key differences between the two. The main difference is their design, with speed tables having a flat top and speed humps having a curved design. This design difference results in varying levels of disruption to vehicle operations and effectiveness in slowing down vehicle speed. In terms of when to use speed tables or speed humps, the decision should be based on the specific road conditions and traffic needs. Speed tables are more suitable for areas with high pedestrian traffic, while speed humps may be more appropriate for locations with heavy vehicular traffic. Other factors that influence the decision to use speed tables or speed humps include the speed limit, road width, and traffic volume. It is important to consult with traffic experts and conduct a thorough analysis of the road conditions before deciding on the most suitable traffic calming device.

Which One is Better?

The debate between the effectiveness of speed tables and speed humps is ongoing. Some argue that speed tables are more effective in slowing down vehicle speed, while others believe speed humps are better in certain situations.

How Do Speed Tables Work?

Speed tables are a type of traffic calming device that are increasingly being used on roadways to control vehicle speed. Their design is different from traditional speed humps, and this section will explain how they work and their impact on traffic flow. First and foremost, speed tables are designed to cover the full width of the roadway. This means that unlike speed humps, which are typically narrower, speed tables span the entire width of the road. This is achieved through the use of asphalt or rubber mounds, which are then modified with a flat top. This allows for a smoother transition for vehicles compared to the abrupt bump of a speed hump. The design of speed tables also includes a gradual incline and decline on either side of the flat top. This helps to slow down vehicles as they approach the speed table and then gradually accelerate as they pass over it. This design feature is important in maintaining a constant traffic flow and minimizing disruption to vehicle operations. In terms of impact on vehicle speed, speed tables have been found to be highly effective. Studies have shown that they can reduce vehicle speeds by an average of 10-15 miles per hour. This is due to the longer length of the flat top, which allows for the entire wheelbase of a passenger car to rest on it. This results in a smoother ride for drivers compared to speed humps, which can cause discomfort and potential damage to vehicles if not traversed at the correct speed. Speed tables are commonly used in areas with high pedestrian traffic, such as school zones and residential areas. They have been found to be particularly effective in reducing speed in these areas, thus improving the safety of pedestrians and reducing the likelihood of accidents. While speed tables are gaining popularity, speed humps are still widely used in many areas. Speed humps have a curved design and are raised areas on the road, unlike speed tables which have a flat top. Speed humps are effective in reducing vehicle speed, but their design can be more disruptive to traffic flow compared to speed tables. In comparison between speed tables and speed humps, it is important to consider the specific requirements of a location. For example, in areas with high traffic volume and speed, speed tables may be more suitable due to their ability to maintain traffic flow. However, in areas with low traffic volume, speed humps may be more cost-effective and still achieve the desired reduction in vehicle speed. The debate between the effectiveness of speed tables and speed humps is ongoing, with varying opinions from traffic experts. However, studies have shown that speed tables are generally more effective in controlling speed and are less disruptive to traffic flow. Ultimately, the decision to use speed tables or speed humps should be based on the specific needs and conditions of a location. In conclusion, speed tables are an innovative traffic calming device that have proven to be highly effective in controlling vehicle speed. Their design, with a flat top and gradual incline and decline, minimizes disruption to traffic flow and provides a smoother ride for drivers. While speed humps are still widely used, speed tables offer a more efficient and effective solution in certain situations.

What are Speed Humps?

Speed humps are another type of traffic calming device that is commonly used to reduce vehicle speed on roadways. They are raised areas on the road with a curved design, typically made of asphalt or rubber. Unlike speed tables, speed humps are not located across the full width of the roadway and are often placed in a series to create a continuous effect. The aim of speed humps is to force drivers to slow down as they approach and drive over them. This is achieved through the gradual incline and decline of the hump, which causes a jolt to the vehicle and encourages drivers to reduce their speed. Speed humps are typically used in areas where there are high pedestrian or cyclist volumes, such as in residential neighborhoods, school zones, and parking lots. There are both benefits and drawbacks to using speed humps. On the one hand, they are effective in slowing down traffic and creating a safer environment for pedestrians and cyclists. On the other hand, they can be disruptive to vehicle operations and cause discomfort for drivers and their passengers. Additionally, emergency vehicles, such as ambulances and fire trucks, may have difficulty navigating over speed humps at high speeds.
