Solar street lights have been available for quite a time now, having originally been designed for use in less developed or isolated areas, or perhaps places where the electricity supply has been disrupted by man-made or natural disasters.

The lighting company is developing a streetlight networking technology, hoping to do something with some smart street lights: when the street light monitors a bus stop, it can send information back to the traffic center and send more Buses; street lights are connected to navigation equipment to provide directions for car owners, or to inform car owners where there are parking spaces; even to help auto-driving cars drive safely on the road.
Street lights are a must-have device on every road. If you can transform these street lights into intelligent street lights, you can greatly enhance the ability of road monitoring. Through these intelligent street lights and Street Lamp networking technologies, when there is a vehicle illegal parking or a traffic accident on the road, the traffic police can grasp the road condition for the first time. In addition, street lights can provide reference data for traffic planners to replace the current expensive monitoring technology. 
Although it is a huge expense to replace all the street lights in the city with smart street lights, in the long run, it is still worthwhile. The new Led Lamp can save electricity budget, and the distance monitoring sensor in the street lamp can solve the traffic congestion problem in the city to a certain extent and improve production efficiency.
Of course, the privacy issues brought by networking can not be ignored. When all the street lights on the roadside are connected, how can we protect personal privacy? I hope that enterprises can face up to privacy issues while developing technology, and finally give a good solution. 
The technology guiding the use of solar energy has progressed significantly to enable projects to be feasible throughout the world. The situation now is that street lights powered by solar energy can be simply and rapidly installed, giving the potential of many years of trustworthy use, with a minimum of maintenance required.
Can urban traffic problems be solved by smart street lights?
There are more and more cars in the city, roads are getting blocked, parking spaces are getting less and less, and parking fees are getting higher and higher. In this case, many cities are forced to use the restrictions on the purchase of cars to curb the growing number of cars. But the number of cars is increasing, and there are only so many parking spaces. If you want to find a parking lot with space, you probably need to run a few more parking lots. The current indoor positioning technology is still not mature enough. Then, using roadside street lights to tell you where there are parking spaces, what is the idea?
