The tunnel sensor market in North America was valued at US$ 1,279.0 million in 2019 and is expected to grow at a CAGR of 4.7% during the forecast period of 2020 to 2027 to reach US$ 1,825.1 million by 2027.
The COVID-19 outbreak is anticipated to affect the growth rate of North America tunnel sensor market in the year 2020 and 2021 and thus there is decline in y-o-y growth during these years. However, the growth is expected to normalize from 2021 onwards and the market is projected to grow at a steady pace. Rising road congestion across the world is demanding infrastructural developments, as well as better cross border connectivity; this has resulted in increasing construction of several road tunnels globally. These tunnels require efficient and reliable solutions for monitoring traffic, airflow, air quality, and fire detection for a smooth movement of vehicles. The tunnel sensors are used for monitoring of obstruction to vision caused by smoke, fog, and exhaust fumes. CODEL International Ltd. and Durag Group are among the road tunnel sensor providers in the market.

Based on solutions, the North America tunnel sensor market is segmented into visibility monitoring, air flow monitoring, air quality monitoring, filter monitoring, fire monitoring, and others. The continuous flow of fresh air across the tunnel is essential for maintaining visibility, as well as controlling the level of toxic gases within the permissible limit. The ventilation systems installed inside the tunnels usually comprise wall or ceiling mounted jet fans. Air flow monitoring sensors are used to ensure optimum airflow within the tunnel and minimize the power consumption of jet fans. Ultrasonic airflow measurement technology is used to achieve optimum airflow inside the tunnel. These sensors are integrated with appropriate software to help users easily monitor and maintain the airflow limit inside the tunnel.
