Smart Pedestrian Crossing System: Technical Leadership in Safe Intersection Management

Ensuring pedestrian safety while organizing vehicle flow at intersections is one of the most complex challenges in modern road engineering. Safety Triangle Contracting provides a revolutionary solution that merges automated monitoring with intelligent control: the Smart Pedestrian Crossing System. This system is meticulously designed to enhance road efficiency and reduce congestion while maintaining the highest safety standards.

I. Engineering Vision & Operational Concept

The system relies on intelligent algorithms, advanced sensors, and sophisticated radar technologies working in perfect harmony. This integrated electronic system aims to:

• Manage Priorities: Granting the right of way to pedestrians or vehicles based on real-time traffic density.

• Improve Flow: Eliminating traffic bottlenecks caused by traditional fixed-time signaling.

• Environmental Efficiency: Improving overall traffic and environmental safety through optimized movement.

II. Intelligent Operating Scenarios (Ultimate Flexibility)

The system supports four programmable operational modes tailored to suit the nature of any intersection:

1. Loop Control System (Pedestrian Priority)

• When the pedestrian button is pressed, the system activates the green signal for pedestrians and the red signal for vehicles.

• It utilizes an underground magnetic sensor placed 50 meters from the intersection to detect approaching vehicles.

• Traffic is transitioned just 5 seconds after activation to ensure rapid response and safe crossing.

2. Automated Congestion Management

• This mode operates automatically based on real-time sensor data.

• It prioritizes the most congested side (whether pedestrians or vehicles) to ensure smooth traffic flow and fair signal time distribution.

3. Radar System (Intelligent Deterrence)

• An advanced radar monitors vehicles at a distance of 80 to 100 meters.

• If a speeding violation is detected, the system holds the vehicle signal at red for an additional 10 seconds to protect pedestrians.

4. Simple Push Button Mode

• Allows pedestrians to activate the green signal directly by pressing a button.

• Signal times for both parties are pre-configured according to specific programming.

III. Technical Details & Centralized Control (Specifications)

IV. Hardware Engineering (Durability & Sustainability)

1. LED Signal Modules

• Material: 100% recycled aluminum housing, resistant to rust and deformation.

• Light Performance: Luminous flux of 250 lumens with a 170° beam angle for wide visibility.

• Protection: IP68 waterproof rating with high-durability polycarbonate lenses.

2. Smart Pedestrian Touch Button

• Compatible with Windows and Android systems and includes an audible warning for visually impaired assistance.

• Low power consumption (< 5W) with a shock-resistant design and a 5-year lifespan.

V. Field Success Story: Al-Qaisariyah Market

The efficiency of this system has been practically proven at Al-Qaisariyah Market in the Al-Ahsa region, Saudi Arabia. The project was characterized by rapid execution (15 to 21 days), leading to a radical transformation in traffic flow and pedestrian safety in this vital historical area.

Conclusion: Smart pedestrian crossings from Safety Triangle are an investment in safety, efficiency, and the future. We don’t just build roads; we build a civilized environment that protects people first.
