Raised Crosswalks
Unlock Audio Lesson
Today, we're going to talk about raised crosswalks! They act like speed tables and serve an important role in pedestrian safety. Can anyone tell me why we might want to raise a crosswalk?
To slow down cars?
Exactly! By raising the crosswalk, vehicles must reduce their speed, making it safer for pedestrians. Now, what materials can we use to make these crosswalks noticeable?
Maybe colored paving?
Correct! Colored paving or thermo-plastic paint can help them stand out. And what do we need to add for visually impaired pedestrians?
Tactile warning tiles?
Spot on! Tactile warning tiles provide critical information for those who can't see well. So, in summary, raised crosswalks slow traffic and enhance safety through clear visibility and tactile aids.
Chicanes and Neckdowns
Unlock Audio Lesson
Next, we're discussing chicanes and neckdowns. Can anyone explain what a chicane does?
A chicane makes cars go around obstacles to slow them down, right?
Exactly right! It effectively reduces vehicle speed while still allowing traffic flow. And what about neckdowns?
They shorten the crossing distance for pedestrians!
Correct! Neckdowns help improve visibility for pedestrians and make it easier to cross. Remember this: shorter crossings mean safer crossings!
Speed Bumps and Rumble Strips
Unlock Audio Lesson
Now, let’s talk about speed bumps and rumble strips. What concerns do we have regarding speed bumps?
They can be too abrupt for people with mobility issues.
Right! We want smoother designs to ensure it doesn't discomfort mobility-impaired users. What about rumble strips?
They make noise to alert drivers, but they can't be too rough.
Great point! We must ensure they don’t interfere with wheelchairs. In summary, both need to be designed carefully to ensure safety and comfort for all road users.
Introduction & Overview

Quick Overview
Standard
The section elaborates on the importance of traffic calming measures such as raised crosswalks, chicanes, and speed bumps, all designed to reduce vehicle speeds and ensure safer pedestrian movement. It emphasizes how these measures increase visibility and ease of access for vulnerable road users.
Detailed
Traffic Calming Measures for Safer Pedestrian Movement
Traffic calming measures are crucial in protecting vulnerable users, especially individuals with disabilities, by reducing vehicle speeds and improving pedestrian safety. The implementation of effective traffic calming strategies contributes to the overall usability and independence of individuals navigating public spaces. This section identifies three key traffic calming measures:
Raised Crosswalks
- Raised crosswalks function as flat-topped speed tables that serve dual purposes: reducing vehicle speed and enhancing pedestrian crossings.
- They should be constructed with surfacing material that contrasts distinctly with the roadway, utilizing colored paving or thermo-plastic paint.
- To ensure safety and awareness, tactile warning tiles must be placed on both sides of the crosswalks to assist visually impaired users.
Chicanes and Neckdowns
- Chicanes are designed to slow down vehicle traffic via lateral shifts in the road, effectively decreasing speed while retaining the traffic flow.
- Neckdowns, also known as bulb-outs, shorten the crossing distance for pedestrians and enhance visibility, allowing for safer navigation across the street.
Speed Bumps and Rumble Strips
- While speed bumps are helpful in regulating speed, care must be taken as abrupt humps can cause discomfort for mobility-impaired users; smoother designs are recommended.
- Rumble strips can be used, but they must be designed thoughtfully to ensure they do not interfere with mobility devices or canes, maintaining smooth surfaces in pedestrian areas.
Overall, these measures not only protect pedestrians but also enhance the quality of the urban environment by promoting safer and more accessible navigation for all users.

Traffic calming helps protect vulnerable users like those with disabilities by reducing vehicle speeds.
Detailed Explanation
Traffic calming refers to design strategies that help reduce the speed of traffic in areas where pedestrians are present. This is especially important for protecting vulnerable pedestrians, such as individuals with disabilities, by providing them with safer environments to move. When vehicle speeds are lower, the likelihood of accidents decreases, and it also becomes easier for pedestrians to cross streets.
Examples & Analogies
Imagine crossing a street as a game of dodgeball. If the players (cars) are moving fast, it's hard to dodge them and get to the other side safely. But if the players move slower, it becomes much easier to avoid them, and you can cross with less worry.

• Flat-topped speed tables functioning as pedestrian crossings.
• Surface should contrast with the road using colored paving or thermo-plastic paint.
• Must have tactile warning tiles on both sides.
Detailed Explanation
Raised crosswalks are essentially elevated pedestrian crossings that help to slow down vehicular traffic and provide a safe area for pedestrians to cross. These crosswalks are designed to be noticeable through contrasting colors on their surfaces, which can aid both sighted pedestrians and those with visual impairments. Additionally, tactile warning tiles help visually impaired pedestrians detect the crosswalk.
Examples & Analogies
Consider a speed bump that you drive over — when you feel that bump, you know to slow down. Raised crosswalks act like those bumps, signaling to drivers that they need to be cautious and aware during pedestrian crossings.
Chicanes and Neckdowns

• Chicanes slow vehicles by introducing lateral shifts.
• Neckdowns (bulb-outs) shorten crossing distance and improve visibility for pedestrians.
Detailed Explanation
Chicanes are curved road segments that make drivers navigate laterally, which slows the vehicles down. Neckdowns, or bulb-outs, extend the sidewalk into the street at corners, reducing the distance pedestrians need to cross. These designs improve pedestrian visibility as they reduce the crossing distance and create a safer environment, making it easier for pedestrians, particularly those with disabilities, to cross.
Examples & Analogies
Think of chicanes like a winding path through a garden that slows your walking speed. It’s a little longer to go around the bends, but it’s easier to enjoy the view. Neckdowns are like having a shorter bridge over a stream rather than a long, meandering path; it makes crossing much quicker for pedestrians.
Speed Bumps and Rumble Strips

• Avoid abrupt humps that cause discomfort for mobility-impaired users.
• If rumble strips are used, they must not interfere with wheelchair wheels or canes — smoother versions preferred in pedestrian spaces.
Detailed Explanation
Speed bumps and rumble strips are tools used to slow down vehicles. However, it's essential that these features are designed thoughtfully. Abrupt bumps can be uncomfortable or hazardous for individuals with mobility challenges, such as those using wheelchairs or canes. Thus, using smoother designs ensures that these individuals can navigate the roadway without jarring disruptions.
Examples & Analogies
Imagine riding a bike over a bumpy road; it can be uncomfortable and hard to control your speed. That’s what speed bumps can feel like for someone in a wheelchair. So we need to ensure that speed bumps are gentle, making the journey smoother and safer for everyone.
