Latest Pedestrian Safety Technologies

• Drive Safe-Tips/Guides-Safety

Pedestrian safety has become a major focus for automakers and technology companies in recent years, as they strive to reduce the number of accidents involving pedestrians.

We look at some of the latest pedestrian safety technologies being implemented in modern vehicles, integrations in a city’s infrastructure, as well as how driver education plays a role in pedestrian safety.

Modern Vehicles

1. Pedestrian Detection Systems

1. Camera and Radar-Based Detection: Many vehicles now feature cameras and radar sensors that can detect pedestrians in the vehicle's path, providing visual and audible warnings to the driver.
2. Automatic Emergency Braking: In addition to warnings, some systems can automatically apply the brakes if the driver fails to respond, helping to mitigate or prevent a collision with a pedestrian.

2. Improved Exterior Vehicle Design

1. Pedestrian-Friendly Front Ends: Vehicle designs are evolving to include more rounded front ends and lower hood heights, which can help to reduce the severity of injuries in the event of a pedestrian impact.
2. Deployable Pedestrian Protection Systems: Some vehicles are equipped with systems that can deploy external airbags or raise the hood to create a more forgiving impact surface for pedestrians.

3. Pedestrian Lighting and Communication

1. Pedestrian Detection Lighting: Vehicles can use specialised lighting systems to illuminate pedestrians in low-light conditions, making them more visible to the driver.
2. Vehicle-to-Pedestrian (V2P) Communication: Emerging technologies are exploring ways for vehicles to communicate with pedestrians, such as through external displays or audible warnings, to alert them to the vehicle's presence or intentions.

Better Streets with AI

AI can play a significant role in designing better streets for pedestrians. By leveraging advanced technologies such as computer vision, machine learning, and data analytics, AI can provide valuable insights and solutions to enhance pedestrian safety and create more pedestrian-friendly urban environments.

Some ways AI can contribute to better street design for pedestrians:

1. Pedestrian Behaviour Analysis

AI systems can analyse pedestrian behaviour patterns using data from various sources, such as traffic cameras, sensors, and mobile devices. This analysis can help identify high-risk areas, pedestrian hotspots, and potential conflict zones between pedestrians and vehicles. By understanding pedestrian behaviour, urban planners and designers can make informed decisions about where to prioritise pedestrian infrastructure improvements.

2. Pedestrian Analytics and Infrastructure Integration

Some cities are already implementing pedestrian detection systems and analytics to better understand pedestrian behaviour and identify high-risk areas for targeted safety improvements. AI can help integrate this data with smart city infrastructure, enabling real-time monitoring and adaptive traffic management solutions to enhance pedestrian safety.

3. Pedestrian-Friendly Design Optimisation

AI can be used to optimise street designs for pedestrian safety and comfort. Machine learning algorithms can analyse various design parameters, such as street widths, crosswalk locations, traffic signal timings, and pedestrian infrastructure placement, to identify the most effective configurations. This data-driven approach can help create streets that prioritise pedestrian needs while balancing other transportation requirements.

4. Pedestrian Detection and Warning Systems

AI-powered pedestrian detection systems can be integrated into vehicles and infrastructure to improve pedestrian safety. These systems can detect pedestrians in real-time and provide warnings or automatic braking to prevent collisions. Additionally, AI can be used to develop vehicle-to-pedestrian (V2P) communication systems, enabling vehicles to communicate their presence or intentions to pedestrians.

5. Simulation and Scenario Testing

AI can be used to simulate various pedestrian scenarios and test the effectiveness of different street designs. By running simulations with different variables, such as pedestrian volumes, traffic patterns, and environmental conditions, urban planners can identify potential issues and refine their designs before implementation.

While AI offers significant potential for designing better streets for pedestrians, it is important to note that its effectiveness ultimately depends on the quality and quantity of data available, as well as the responsible and ethical implementation of these technologies. Collaboration between AI experts, urban planners, and transportation authorities is crucial to ensure that AI-driven solutions prioritise pedestrian safety and create more liveable and sustainable urban environments.

Driver Education

Driver education also plays a crucial role in maximising the effectiveness of pedestrian safety technologies. While these technologies are designed to enhance safety, their impact can be amplified when drivers are properly educated on their usage and limitations.

• Awareness: One key aspect of driver education should focus on raising awareness about the various pedestrian safety features available in modern vehicles, such as pedestrian detection systems, automatic emergency braking, and pedestrian-friendly exterior designs. Drivers should understand how these technologies work, their capabilities, and their limitations, to ensure they are used effectively and not relied upon blindly.
• Vigilance: Driver education should emphasise the importance of remaining attentive and vigilant, even when vehicles are equipped with advanced safety features. Pedestrian safety technologies are designed to assist drivers, but they should not be treated as a substitute for responsible driving practices, such as maintaining a safe speed, avoiding distractions, and being aware of surroundings.
• Safety and caution: Driver education can play a role in promoting safe driving behaviours around pedestrians, such as yielding to pedestrians at crosswalks, maintaining a safe following distance, and being cautious in areas with high pedestrian traffic. By instilling these practices, drivers can better complement the effectiveness of pedestrian safety technologies and create a safer environment for all road users.
• Staying up to date: Driver education programmes should stay up-to-date with the latest advancements in pedestrian safety technologies and incorporate them into their courses. As new technologies emerge, drivers should be educated on their proper use and integration with existing safety features, ensuring a comprehensive understanding of the available tools for enhancing pedestrian safety.

While technology has the potential to significantly improve pedestrian safety, the effectiveness ultimately depends on proper implementation, driver education, and responsible use. Additionally, ongoing research and development are necessary to address the unique challenges posed by pedestrian safety in various environments and scenarios.

FAQ’s

1. What are the main causes of pedestrian accidents in South Africa?

The primary causes of pedestrian accidents in South Africa include illegal road crossings, not using designated pedestrian crossings, poor visibility due to inadequate street lighting, drunk driving, speeding, and failure to adhere to traffic signals by both drivers and pedestrians.

2. How can pedestrians ensure their safety while walking on South African roads?

Pedestrians can enhance their safety by using pedestrian crossings, adhering to traffic signals, wearing visible clothing, especially at night, walking on sidewalks or facing oncoming traffic if no sidewalk is available, and avoiding distractions like using mobile phones while walking.

3. What are the responsibilities of drivers to ensure pedestrian safety?

Drivers should always be vigilant, especially in areas with high pedestrian traffic. They should adhere to speed limits, yield to pedestrians at crosswalks, avoid driving under the influence of alcohol or drugs, and be cautious when
