Silent Construction Vehicle Guidance System-Otonashikun | Automated Measurement Systems

This system enables silent guidance of construction vehicles without using whistles, horn blasts, or other audible cues. Guidance instructions are provided through an LED display panel and in-vehicle radio announcements, making the system highly effective for nighttime operations and noise-sensitive environments.

① Reliable FM Audio Guidance(human-like voice)

Built-in FM transmitter audio guidance allows drivers to hear spoken instructions directly on their car's FM radio.
② Environmental Considerations for Nighttime and Urban Areas (silent guidance)

Because vehicles can be guided without emitting external sound, there is no noise disturbance for nearby residents. This allows safe and considerate use even at nighttime construction sites or in urban areas where environmental sensitivity is required.In areas where such considerations are unnecessary, using the radio also allows surrounding workers to hear the guidance instructions.
③ Bright, Highly Visible Panel (high-brightness full-color display)

To ensure clear visibility, the system uses a high-brightness LED (SMD) panel, improving daytime visibility.In addition, the full-color display provides vivid, multi-color visuals and animations, delivering easy-to-understand screens that enhance intuitive recognition.
