The Ningxia section of Qinglan Expressway (Ningxia section from Dongshanpo to Maojiagou) is an important section of the national expressway network. channel; form a more complete inter-provincial transportation network.
When Qinglan Expressway encounters special weather such as fog, it is very prone to traffic accidents. In particular, the danger of dense fog and thick fog in local road sections is the cause of many major safety accidents. Driving from a normal road section into a dense fog area at high speed, due to the sudden change in visibility, the vision becomes blurred, and the driver is prone to make judgment and operation errors. Can cause chain reaction, form the catastrophic traffic accident of continuous rear-end collision of many vehicles. This time, the Ningxia section of Qinglan Expressway has newly added a
road studs device system for foggy road guidance and warning. There are three modes: road contour enhancement mode, driving active guidance mode, and rear-end collision prevention warning mode.
1. The road outline enhancement mode of the
Road Studs device, which induces driving safety on foggy roads.
In the induction
Road Studs system, the yellow induction
Road Studs light of the induction fog lamp is displayed as a steady state.
2. Foggy highway driving safety guidance device driving active guidance mode.
In the
Road Studs induction system, the luminescent display components of the
Road Studs induction device should be able to prompt the safe distance between the front and rear vehicles through the change of the working state.
When a vehicle passes the
Road Studs induction device, it can trigger the red warning lights of a specific group of upstream induction devices to light up, forming a red trail to indicate the presence of a vehicle in front of the rear vehicle and the safe driving distance of the following vehicles. At this time, the yellow induction lights of other
Road Studs induction devices should flash synchronously, and when the vehicle moves forward and passes the next group of induction devices, the red trail will move forward synchronously with the vehicle dynamics.
3. Foggy highway driving safety
Road Studs induction device to prevent rear-end collision warning mode
In the guidance system, the luminescent display component of the
Road Studs guidance device for road driving safety in foggy days can prompt the safe distance between front and rear vehicles through changes in working status.
When a vehicle passes by, the red light of the upstream specific
Road Studs induction fog light can be triggered to form a red trail to indicate that there is a car ahead of the subsequent vehicle and a safe distance should be maintained. At this time, the yellow lights of other
Road Studs inducing fog lights flash synchronously. When the vehicle passes the next set of
Road Studs inducing fog lights, the red trail will move forward synchronously with the dynamics of the vehicle.
