French In modern cities where cars, bikes and new micromobility modes share the roads, smart signal control is essential to cut congestion, improve air quality and ensure smoother journeys. EchoWave by Sinowatcher Technology is an integrated radar-and-video detector that feeds SCOOT with near-instant data on occupancy, queue length and speed.
EchoWave combines an 80 GHz radar and an HD camera (up to 8 MP) to monitor up to six lanes from a single mounting point. It measures precisely how long each approach is occupied, calculates the actual queue distance and reports speeds with only ±0.1 m/s error. All this runs on under 24 W of power, inside an IP67 enclosure, and installs on existing poles or brackets in hours—no pavement cutting required.
SCOOT continuously recalculates phase splits and offsets every minute, but its performance depends entirely on data quality. Traditional inductive loops are costly to install, prone to damage during roadworks and offer limited insight. EchoWave delivers fresh, high-fidelity data every 5–10 s, letting SCOOT adapt immediately when a bus brakes or a surge of cars rolls in.
In Guangzhou’s Central Five Districts, pilot deployments of radar-video detectors between 2020 and 2023 produced striking results. Detection uptime jumped above 98 %, false calls due to pavement work or heavy bicycle traffic almost disappeared, and maintenance interventions fell by more than 50 %. With more reliable occupancy and queue measurements feeding SCOOT, average intersection delays dropped noticeably—even during peak hours—freeing maintenance crews to focus on proactive network improvements.
Beyond saving space and avoiding trenches, EchoWave classifies vehicles—cars, trucks and motorcycles—so SCOOT can tailor green times to the traffic mix. Heavy-vehicle surges automatically trigger longer greens, boosting throughput without manual retuning. And with fiber-optic or Ethernet connectivity, the system stays rock-solid even at complex intersections.
The economic case is equally compelling. Skipping pavement works can cut deployment costs by up to 80 % compared to loops. Low power draw keeps energy bills small, and a mean time between failures over 100 000 h makes maintenance virtually negligible. Many cities see full return on investment within months, all while offering a more sustainable, cost-effective solution.
Engineers and traffic managers appreciate a contactless detector with no buried components to fail. EchoWave needs only a power adapter and a data link, eliminating worries about short circuits or cable interference. Mounting on existing “L” poles streamlines logistics and accelerates go-live schedules. For sales teams, EchoWave is a standout selling point: an all-in-one solution that minimizes disruption, optimizes resources and proves ROI quickly. When pitching to city authorities or road operators, you deliver rapid deployment, high-fidelity data and savings on both installation and operations.
Cities already running SCOOT can integrate EchoWave without major software changes—simply map its occupancy and queue outputs into SCOOT’s parameters. And cities yet to adopt adaptive control will find in this combo the fastest, most economical path to smart signals.
EchoWave isn’t just a detector; it’s the accelerator SCOOT needs to become a truly adaptive brain that anticipates demand, cuts CO₂ emissions and elevates driver experience. With rapid deployment, near-zero maintenance and rock-steady data, Sinowatcher Technology offers the formula to transform any intersection into an optimal-flow point from day one.
