Solar Road Markers for Urban Road

Urban Road Traffic Safety Needs and Challenges Urban roads are the ‘blood vessels’ of urban operation, carrying a high density of pedestrian and vehicular traffic. During peak hours, vehicles and pedestrians are intertwined, and traffic transitions are frequent. Once lighting is insufficient at night or road markings are ambiguous, safety hazards ensue. Therefore, a set of efficient road marking system is crucial to guarantee the traffic safety of urban roads. Innovative Value of Solar Road Signs Solar road signs, as a new type of intelligent transport facility, bring new solutions for urban road safety management. It gets rid of the dependence of traditional signs on the power grid and uses solar energy to achieve autonomous light-emitting, which not only improves the visibility of road signs, but also conforms to the concept of green environmental protection.

The advantages of solar road markers intelligent lighting

1. Adaptive brightness adjustment solar road signs with built-in light-sensing elements, like a keen ‘eye’, can perceive environmental light changes in real time. During the day, the solar panel absorbs sunlight and converts light energy into electrical energy stored in the battery. At night, when the ambient light becomes weak, the light-sensing element will trigger the system to automatically adjust the luminous intensity of the sign. In areas with low light, the luminance of the sign is increased to ensure that it is clearly visible; while in road sections with sufficient street lights, the sign reduces its luminance to save electricity. This self-adaptive adjustment function ensures that the sign can play its best role in all-weather conditions.

2. Dynamic warning mode is different from traditional static signs, solar road signs have dynamic display functions such as flashing and colour changing. At intersections, the sign flashes at a certain frequency, reminding drivers to slow down in advance; at pedestrian crossings, the sign can change to eye-catching red, warning vehicles to yield to pedestrians; in the construction area, the sign is constantly changing colours, guiding vehicles around. These dynamic warning modes can effectively attract the attention of drivers and pedestrians, significantly improving road traffic safety.

Energy saving and environmental protection features

1. Zero carbon emission solar energy is a kind of clean energy, inexhaustible. Solar road signs do not consume traditional electricity and do not produce greenhouse gas emissions such as carbon dioxide during use. With the city's promotion of the ‘carbon neutral’ goal, the application of solar road signs helps to reduce carbon emissions in the field of transport and contributes to the construction of green transport in the city.
2. Low-energy consumption design Solar road signs adopt low-energy consumption design with high luminous efficiency of its LED light source, which requires only a small amount of solar energy to maintain long-time operation. Compared with traditional illuminated signs, solar road signs do not need to pay high electricity costs, which greatly reduces the operating costs of urban public facilities. In the long run, its energy-saving advantage will bring significant economic benefits.

Installation and Maintenance Convenience

1. Rapid installation of solar road signs is very convenient, without the need for complex wiring work. For embedded signs, it is only necessary to punch holes in the road surface, embed the sign and fix it; attached signs can be directly pasted on the road surface or kerbstone. This kind of installation has very little impact on the normal traffic of urban roads, especially suitable for urban road reconstruction and upgrading projects, which can quickly complete the installation without affecting the traffic.
2. Intelligent failure warning solar road marking built-in monitoring system, real-time feedback of its own work status. Once the battery power is insufficient, LED damage and other faults, the system will automatically send out warning information. Managers through mobile phones or computer terminals, you can get fault information in a timely manner, quickly locate the problem signs, reducing the cost and time of manual inspection, greatly improving the maintenance efficiency.

Urban roads applicable solar road signs type by function classification

1. guide class logo guide class logo is mainly used for lane line, guide line and other positions, through continuous light, clear road direction. In the multi-lane urban trunk roads, this type of sign can help drivers clearly distinguish the lane boundaries, avoid changing lanes at will, maintain the correct driving track, thus enhancing the efficiency of road traffic.
2. Warning Signs Warning signs play an important role in dangerous road sections such as intersections, sharp turns and school areas. They remind drivers of potential dangers by flashing or changing colours. For example, in the vicinity of schools, warning signs will flash in eye-catching yellow to remind drivers to slow down and ensure the safety of students.
3. Information Signs Information signs are used to convey information about specific road use rules, such as bus lanes, bicycle lanes, and so on. They are marked with specific colours or patterns so that drivers and pedestrians can understand them at a glance. In bus lanes, blue information signs can clearly distinguish between lanes, regulate the movement of social vehicles, and improve the efficiency of bus operations.

Classification by installation form

1. Embedded road signs Embedded road signs are firmly embedded in the road surface, flush with the road surface. This design makes it has a strong anti-crushing ability, even in the traffic flow of the main road, can also withstand the frequent crushing of vehicles. At the same time, embedded signs will not affect the comfort of vehicle traffic, is the ideal choice for urban trunk roads.
2. Attached road marking Attached road marking is installed on the road surface or kerbstone by sticking or fixing. Its installation is flexible and suitable for pavements, non-motorised roads and other areas. In some narrow streets or community roads, attached signs can be quickly installed to provide clear road guidance for pedestrians and non-motorised vehicles.

The application of solar road signs in the urban road scene urban main road application

1. Lane separation and guidance in the two-way multi-lane urban trunk roads, solar road signs can clearly divide the lane boundaries. During the daytime, the logo and road markings cooperate with each other; at night, the logo is actively illuminated, even in the absence of street lights, it also allows drivers to accurately judge the location of lanes, reducing traffic accidents caused by lane changing and enhancing traffic efficiency.
2. Junction traffic optimisation intersection is the high incidence of traffic accidents. Solar road signs play an important role in assisting traffic signals at intersections. By flashing or changing colours, the signs guide vehicles to pass in an orderly manner and remind drivers to pay attention to traffic rules. In some complex intersections, the signs can also indicate the direction of travel of turning vehicles, reducing the incidence of violations such as running red lights and jumping the queue.

Sub-arterial and branch road applications

1. Community peripheral road safety at the entrance and exit of the residential community, the flow of people and traffic is relatively concentrated, especially in the morning and evening rush hours. Solar road signs installed on the roads around the community can effectively remind drivers to slow down and ensure the safety of residents travelling. At the same time, the clear guidance of the sign also facilitates the entry and exit of community residents and foreign vehicles.
2. The traffic safety of the roads around the school area protection school is crucial. Solar road signs set warning signs, such as speed bump signs and attention to pedestrians signs, at school entrances and nearby road sections. By flashing or changing colours, these signs alert drivers and create a safe environment for going to and from school, greatly reducing the risk of traffic accidents for students.

Special Area Application

1. Construction section warning During road construction, the safety protection of the construction area is particularly important. Solar road marking in the construction section by flashing warning, reminding the vehicle detour. Its high visibility and dynamic display function can effectively avoid construction personnel and passing vehicles collision, to protect construction safety and road traffic order.
2. bus lane management bus lanes are set up to improve the efficiency of bus operations, but some social vehicles illegally occupy the lanes occur from time to time. Solar road marking clear bus lane boundaries, through a specific colour and pattern, regulating social vehicles. At the same time, the logo of the continuous light, even at night can also clearly show the scope of the special road, to ensure that the priority right of passage of public transport vehicles.
