ClairSRS Wired is a wired-powered smart road stud equipped with a 5x6 matrix of ultra-bright LED lights. It can display various signals such as straight, stop, no entry, and left turn, and supports custom complex patterns. This smart road stud can be connected to signal control devices or video and radar detection systems, enabling applications such as dynamic road rights, tidal lanes, variable lanes, lane-sharing for left turns, and smart crosswalks. It integrates seamlessly with traffic management systems, enhancing road safety and management efficiency.
Key Features
Ultra-bright LED Beads: The device features ultra-bright LED lights that can actively emit light in low visibility conditions or at night, enhancing road visibility and driving safety. Even during the day, the LEDs provide effective road guidance and information dissemination.
LED LED Display Effect: Features a 5x6 matrix of LED beads capable of displaying signs such as straight, stop, and no entry. Custom shapes can also be accommodated.
Temperature Management: Equipped with a built-in temperature sensor, the device automatically adjusts the current to prevent overheating. This helps maintain the stability of the LEDs, extends their lifespan, and ensures they consistently output high brightness in various environmental conditions.
Flush Ground Installation: With a patented dual-stage light refraction design, the LED beads of the road stud do not need to protrude above the road surface while still achieving excellent long-distance visibility. The road stud remains flush with the ground, ensuring it does not interfere with snow plows or other road maintenance equipment.
Infrared Communication: Can be equipped with an infrared communication module to detect specific vehicles with infrared transmitters, such as BRT or buses, enabling V2X applications like dynamic road rights.
Wide-Temperature and Pressure-Resistant Housing: Made of reinforced PC material, the housing can withstand operating temperatures ranging from -45°C to 85°C and pressure up to 26.5 tons.
NFC Programming and Remote Firmware Upgrades: NFC programming allows for configuration of location information, device reboot, firmware updates, parameter adjustments, mode switching, and information retrieval.
Application Scenarios
Smart Crosswalk System: The Smart Crosswalk System is implemented in both signal-controlled and non-signal-controlled urban road sections and intersections to provide warnings for pedestrian crossings at intersections.
Functionality: - Pedestrian Detection: Video detectors monitor pedestrian crossing needs and red-light violations. - Vehicle Detection: Vehicle detectors assess traffic flow, speed, and real-time dynamics upstream and downstream of the crosswalk. - Warning Lights: Embedded crosswalk warning lights in the road surface provide alerts to both pedestrians and vehicles, ensuring safer passage and timely warnings.
Variable Lane: Lane Configuration: A row of smart road studs is installed on each side of the variable lane, supporting the switching between straight-through and left-turn signals. The shape and color (red, yellow, green) of the lights can be controlled by the signal control device.
1. When Defined as a Straight-Through Lane: - Green Light: The road studs display a green straight-through arrow on the ground, which can flash or scroll. - Red Light: The road studs display a red straight-through arrow on the ground, which can flash or scroll. 2. When Defined as a Left-Turn Lane: - Green Light: The road studs display a green left-turn arrow on the ground, which flashes synchronously. - Red Light: The road studs display a red left-turn arrow on the ground, which flashes synchronously. 3. Transition from Green to Red: When the light changes from green to red in any state, all road studs will flash yellow on the entire surface to maintain synchronization with the traffic signal light and timing.
Dynamic Road Rights Scheme for BRT Lanes and Bus Priority Lanes: The smart road stud system for bus priority lanes allows general vehicles to use these lanes while ensuring that BRT/bus vehicles retain priority. This approach maximizes road resource utilization, alleviates traffic pressure, and enhances public transport reliability.
- When No Special Vehicles are Present: The road stud displays a green arrow that scrolls from bottom to top, indicating that general vehicles are permitted to use the BRT lane. - When a Bus is Detected: The road stud activates a red "X" light within the detection range, prohibiting general vehicles from using the lane. - Detection Range: The detection range of the road stud can be adjusted. If no bus is detected, the road stud continues to display the green arrow, allowing general vehicles to use the lane, thereby improving traffic flow and reducing congestion.
Tidal Lane: - Morning Peak Period: In the south-to-north direction, when the green light is activated for straight-through traffic, the road studs installed in the tidal lane will also turn green, displaying a green arrow for south-to-north straight-through traffic. The arrow can flash or scroll as needed. - Evening Peak Period: The road studs will display a green straight-through arrow in the south-to-north direction, synchronized with the traffic signal lights, to implement the tidal lane scheme effectively.
