Cabines d'appel routières : assurer la sûreté et la sécurité sur la route
Highway call boxes are roadside emergency communication systems that provide a means for motorists to contact emergency services in case of a breakdown or accident. They have been in use since the early 1970s, and have proven to be an effective tool in promoting road safety and security.   The call boxes are typically placed at intervals along the highway, and are easily recognizable by their bright colors and reflective markings. They are designed to be durable and weather-resistant, and are capable of withstanding extreme temperatures and harsh weather conditions.   The call boxes are activated by pressing a button, which connects the caller to a central dispatch center. The dispatcher can then communicate with the caller, assess the situation, and dispatch emergency services if necessary.   One of the key benefits of highway call boxes is that they provide a reliable means of communication in areas where cell phone coverage may be limited or non-existent. This is particularly important in rural areas, where breakdowns or accidents can occur in areas with no nearby towns or facilities.     In addition to providing a means of communication, call boxes also serve as a deterrent to criminals and other potential threats...
