Urban streets are increasingly crowded, with cars, bicycles, e-scooters, and pedestrians sharing limited space. This complex traffic mix creates high-risk zones where accidents are common, particularly along bike lanes and pedestrian paths. Traditional monitoring systems, such as cameras or loop detectors, often struggle to provide reliable detection in these dynamic urban environments due to occlusion, poor lighting, or adverse weather conditions.
Linpowave’s millimeter-wave (mmWave) radar technology offers a robust solution. By detecting and tracking multiple moving objects in real time, mmWave radar improves safety, supports traffic management, and provides actionable data for urban mobility planning.
Challenges in Urban Bike Lanes and Pedestrian Zones
Several factors contribute to safety risks in city streets:
-
Mixed traffic flows: Bicycles, e-scooters, and pedestrians often move unpredictably alongside vehicles.
-
Limited visibility: High buildings, parked vehicles, and street furniture obstruct camera views.
-
Weather sensitivity: Rain, fog, and low-light conditions reduce camera effectiveness.
-
High pedestrian density: During peak hours, crowded sidewalks and crossings increase collision risk.
According to urban traffic studies, bike lane and pedestrian accidents account for a significant portion of city traffic injuries, highlighting the urgent need for advanced detection systems.
How Linpowave Radar Improves Safety
Millimeter-wave radar overcomes these challenges by providing accurate, all-weather, multi-target detection:
-
Simultaneous tracking: Detects bicycles, e-scooters, and pedestrians, measuring speed, distance, and trajectory.
-
All-weather performance: Functions reliably in rain, fog, snow, or nighttime conditions.
-
Low latency: Provides instant feedback for traffic control systems or connected vehicles.
-
Integration with urban ITS: Data can be shared with smart traffic signals, crosswalk alerts, and public safety monitoring systems.
For example, Linpowave’s urban radar solutions are deployed in city districts to monitor bike lanes and pedestrian crossings, enabling dynamic alerts to drivers and automated safety systems.
Real-World Application: Protecting Cyclists and Pedestrians
Consider a busy city intersection with a dedicated bike lane. A cyclist enters the lane just as a vehicle prepares to make a right turn. Without radar, the driver may not detect the cyclist due to blind spots, leading to potential collisions.
With Linpowave radar installed, the system continuously tracks all moving objects in the lane and generates early collision warnings. These warnings can be displayed via connected in-vehicle alerts, roadside displays, or smartphone notifications for cyclists, significantly reducing the risk of accidents.
Similarly, in pedestrian-heavy zones such as school areas or transit hubs, radar systems monitor crowd movements and can detect sudden crossings or jaywalking, allowing traffic management systems to adjust signal timing or alert approaching vehicles.

Benefits Beyond Safety
Beyond preventing collisions, radar monitoring contributes to urban traffic efficiency:
-
Smooth traffic flow: Early warnings prevent abrupt braking and lane changes.
-
Data for urban planning: Continuous radar monitoring provides statistics on bike and pedestrian traffic, aiding city planners in designing safer streets.
-
Support for autonomous vehicles: Radar data can enhance AV perception in crowded urban environments.
By integrating mmWave radar into urban mobility infrastructure, cities can create safer, smarter, and more responsive traffic systems.
FAQ: Urban Radar for Bike and Pedestrian Safety
Q1. Can mmWave radar detect small, fast-moving objects like e-scooters?
Yes. Millimeter-wave radar tracks multiple objects simultaneously, including bicycles, e-scooters, and pedestrians, with high accuracy and low latency.
Q2. Does radar work at night or during bad weather?
Absolutely. Radar waves penetrate rain, fog, and darkness, maintaining reliable detection where cameras may fail.
Q3. How can radar data improve urban traffic management?
Radar data can be integrated into smart traffic lights, pedestrian alerts, and connected vehicle systems to optimize flow and reduce accidents.
Q4. Are there examples of cities using Linpowave radar?
Yes. Several urban districts deploy Linpowave radar solutions to monitor bike lanes and pedestrian crossings, improving both safety and traffic efficiency.
