Public awareness health and safety, population size and cooperation from the public dominate the social factors.
The selection of treatment facilities requires the evaluation and integration of views and perceptions of all stakeholders (local authorities, communities, interest groups such as non-governmental organizations (NGOs) and international funding agencies [1. 6].
Social impacts are public health and safety, traffic congestion, odour effects, population growth, housing type, employment, skills, cooperation and public awareness.
For social factors, public awareness, public health and safety, cooperation and odour effects dominated traffic congestion, housing type and population growth (Table 1).

Introduction With the development of the economy and the rapid increase of vehicle in recent time, the situation of the urban traffic are getting worse especially in the peak time and some traffic demand management measures are taken to establish an effective public traffic system in order to ease the traffic congestion.
Domestic and foreign scholars have done some studies on the planning, operation and safety management and routing optimal design of commuter bus.

In Korea, ‘airspace’ is defined as ‘the designated range of space above land or water to ensure the safety for activities of aircrafts, light-aircrafts, and ultra-light-flying -equipment’.
International standard classifies the airspace to which low altitude route belongs as Class E, but Korea’s standard classifies it as Class D considering limited airspace condition.
Therefore, the operational environment system must be established to provide 24-hours ATS to SmartUAV or GCS operating SmartUAV from air traffic control unit for the safety operation of SmartUAV.
In Korea, the vast majority of all air traffic monitoring is carried out by ground based secondary surveillance radars, and aircraft based radar transponders.

But, we can formulate reasonable repair and maintenance plans to increase the efficiency of track maintenance and ensure safety, if the prediction of track irregularity is effective.
The international union of railway technical research institute (ORE) defined the standard deviation and average of sinking, got the predict formula of the development rule of track longitudinal level irregularity using the sinking average [4].
Its geometric condition affects the running safety, stability and comfort of train.

Automotive engineers have to pay more attention on vehicle active safety.
The German Alliance Insurance Association research shows that 25% of serious injury accidents and 60% of deaths in traffic accidents are caused due to vehicle sideslip [1].
Therefore, researches are focused on how to improve handling and stability for safety while driving at high speed.
