City streets | Pedestrian and cyclist counting with TAC-B 3D-WP
The SensMax TAC-B 3D-WP Wi-Fi radar is a practical solution for pedestrian and cyclist counting on city streets. It detects people moving in both directions and delivers clear statistics for urban mobility planning and street use analysis. Cities use these numbers to understand footfall, compare locations and plan investments more effectively.
Pedestrian and bicycle footfall counting on an urban street using TAC-B 3D-WP
Why count pedestrians on city streets
Counting shows how many people pass key streets and squares. The data reveals which areas are most used, helps compare before/after results of projects and supports budget planning. It also guides where to improve sidewalks, add seating or expand bicycle lanes.
Key benefits
- Pedestrians and cyclists. Detects walkers, bicycles and scooters in both directions.
- Accurate results. Up to 99% accuracy in normal density and reliable operation in crowded areas.
- Wide coverage. Up to 100 m² with a 120° angle—ideal for sidewalks and street segments up to 10 meters wide.
- Privacy by design. Radar counts movement only; it does not film or scan Wi-Fi/Bluetooth devices.
- Wi-Fi connectivity. Sends data to SensMax Cloud or to your systems via MQTT/API over local Wi-Fi.
- Resilient operation. Internal SD card stores data during network outages; uploads resume when Wi-Fi returns.
- All-weather use. Works in rain, fog, snow, bright sun and complete darkness.
Performance and accuracy
Tests show up to 99% accuracy when density is moderate and about 93% in crowded conditions. Best results are achieved when the sensor is mounted 2.5–3 meters high with a clear view across the street. The radar detects pedestrians, cyclists and scooters equally well during day or night.
Integration and analytics
View live and historical reports in the SensMax cloud (hourly, daily, weekly and seasonal). For advanced workflows, export data via MQTT or API to your BI, GIS or smart city platforms. TAC-B 3D-WP uses local Wi-Fi for data delivery; no cellular plan is required.
Installation
Mount the TAC-B 3D-WP on a sidewall, lamp post or pole at 2.5–3 meters height with a clear line of sight. The sensor is housed in a weather-protected enclosure (IP68). Power is supplied from a standard AC 220 V → DC 12 V adapter; an optional SensMax Mini UPS can provide up to 7 hours of backup. Configuration is completed from a mobile phone. After setup, the system runs automatically with no regular maintenance.

FAQ – common questions
- Does it need the internet to work? It counts locally and stores data on the SD card if Wi-Fi is down, then uploads when the network is back.
- Is it privacy compliant? Yes. It uses radar only, does not film and does not scan phones (Wi-Fi/Bluetooth).
- What is the best mounting setup? 2.5–3 meters high with an open view across the sidewalk or street segment.
- Can we integrate data into our systems? Yes, via MQTT or API into BI, GIS or smart city platforms.
- What power options are available? 220 V → 12 V adapter; optional SensMax Mini UPS for short-term backup.
