However, LED has many characteristics like safety in use and low consumption, of which the energy consumption is decreased by 80% in contrast to incandescent lamps with the same lighting efficiency, thus LED is particularly suitable for the application in public places.
For example, the management of scenic spots includes, to control the traffic flow in the scenic spots and promote green environmental protection travel; to create free bicycle service points, where visitors can borrow bicycles for a free ride to reduce carbon emissions in the travel, in addition ,the side-effects can be reduced on climate and ecological environment of ecological preservation; in the tourism season and holidays, it is to guide tourists for public traffic transfers in tourist transport centers; it is to establish transport systems of environmental protection and energy conservation in the scenic spots.

The vibration response analysis for a car left front shaft head based on user conditions GUO Zhi-ping1,a, WANG Lian-lei1,b, ZHOU Wei2,b, LI Wen-liang2,b, ZHANG Chao1,b, LI Bao-zong1,b 1College of Mechanical Engineering, Inner Mongolia University of Technology, Hohhot, China 2Key Laboratory of Operation Safety Technology on Transport Vehicles Ministry of Communication, Research Institute of Highway Ministry of Transport , Beijing, China agolf_fan@qq.com, bincb-maybach@hotmail.com Keywords: Vehicle vibration, Road test, Vibratory response, Load spectrum Abstract.
When the connection parts of the vehicle appears loose, it will lead to a new vibration, and result in parts damaged increasingly, which affects the vehicle safety.
With the current rapid development of the domestic automobile, vehicle safety and reliability have got widespread concern, so the study of the safety problem caused by vehicle vibration in the specific user conditions has important application value. 1.
The user condition data and the road spectral data obtained under these conditions can be applied to vehicles test on the bench or simulation, and can also be used to EVP road productions. 1.1 User Conditions analysis Establishing user target is based primarily on the user’s vehicle type, road conditions (including local traffic, weather conditions) and the driver’s operation habit.

Introduction Based on data from WHO, the prevalence of traffic accidents with head injuries in many developing countries, such as Indonesia was high, as much as 90%.
Traffic accidents with head injuries are considered to be severe problems since they can lead to death or other negative impacts.

The International Energy Agency (IEA) has set a goal to cover more than 25% of world energy needs in transportation sector by biofuel by 2050[8].
LCA does not cover issues of public health, hygiene and site or procedure safety.
For example, it analyzes the effect of transportation from air and water contamination and energy usage viewpoint, while it leaves behind the risk of accident or infrastructural saturation (mainly caused by increase of traffic congestion) [13].
