Recently, the problem of global warming has issued seriously, so Green IT(Information Technology) using RFID/USN is concerned in order to solve environmental problems. In this paper, we implemented that public area like an underground parking lot could reduce unnecessary energy consumption used by lighting control system based on Ubiquitous Sensor Networks. The lighting control system for underground parking lot is comprised of intersection nodes for watching cars enter and leave, and light node for controlling light. It applies the routing protocol based on hierarchical cluster, hierarchical addressing method, and probability filtering method for the specific place like an underground parking lot. The result after experiments shows that the lighting control system could decrease electrical energy consumption to around 61.7%.

Nowdays, The LED Illumination system can achieve lower power consumption and has a longer life-time compared to the fluorescent lamp system. Visible Light Communication(VLC) is wireless optical communication to use visible light of LED. This paper designs the indoor navigation of Location-Based Service(LBS) using LED illumination. and the parking guidance system using VLC in the underground parking lot. We show the result of experimentation and confirm possibility of the parking guidance system.

In this paper, we have designed and implemented lamp control system in underground parking place using WWW. The proposed system consists of lamp control system which is connected by RS-485 communication bus and monitoring system (WebPL) which can provide web interface using the web server. The lamp control system is controlled through a user command within the monitoring system (WebPL), senses moving object and turns lamps in underground parking place on or off. The monitoring system displays the status values of on or off received from lamp control system on the web browser and can real-timely control lamps in underground parking place on the web browser.

In this paper, we show the implementation of the low-cost RF transceiver module for parking control system. Super regenerative receiver scheme was adopted for this module due to its simplicity, low-cost, low power consumption and small number of components to improve reliability of the systems. For improving communication error rate by collision and in-band noise, dual-channel hopping scheme was adopted. Testing prototypes under the environment of simultaneous transmissions, we verified that the designed scheme is able to improve the success rate of data transmission of wireless parking control system cost effectively.

In this study, we developed the inverter system to control Induction motor for the vertically circulation parking facility. In the case of calling a pallet, a car parking space, we basically stoned conventional system's problems, pallet is uncontrollable to the fixed position and braking system was worn by forcer braking with remaining speed. Also, by appling to converter controller, added to power regenerative control function, we confirmed the reduce of power supply capacity and the energy saving effect according to increasing operation frequency. The validity of this system is verified by 55kw induction motor driving system. Via this study, the proposed system shows the efficient use of parking facility and good operation characteristics by implementing position and speed control effectively on condition of load and shows energy saying effect by power factor control for the vertically circulation parking facility operation.

For a integrated system to control several parking lots within a commercial district, it is required to guide a route to a nearest neighbor parking lot considering diverse realtime constraints such as realtime status of parking lots and changes of an access route. This paper proposes an optimized route-searching technique of integrated parking control system considering realtime contraints. In concrete, it proposes a method of researching a route in the surrounding area considering various status of parking lots that a customer designates (no parking, closed, under construction, no passing of a road) and deals with a route-searching technique optimized for each situation in detail.

The main purpose of the research is to prevent residents who are using underground parking lot from being exposed to pollusion, and to allow them to enjoy clean indoor environment. The study subject for the research are underground parking lots in 20 different apartments, 4 of them were constructed before 2000, 10 were constructed from 2000-2010, and the rest were constructed after 2010. By analyzing the air quality in these underground parking lots, we found out that O3, NO2, CO, PM10, Radon in all parking lots were not excessive compared to the standard limit. TVOC rate was measured with the value in between 312 ~ 2,137㎍/m3, with CO2 value in between 193~1,824 ppm, and HCHO with the value in between 0.01~1.52ppm. The lightning system in underground parking lots in apartments constructed before 2000 were using manual light control system, while automatic light control system was used in all apartments constructed after 2000, and the brightness of parking lots in apartments constructed before 2000 was quite low. The apartments constructed after 2000 are performing cleaning and ventilation due to management agreement, while the apartments constructed before 2000 are not performing regular cleaning and there was no mechanical ventilation system installed. The difference of indoor air quality was significant seasonally, daily, and yearly (year of construction), while illuminance was significantly different yearly.

A parking-assist system is defined that a driver adjusts vehicle velocity through brake pedal operation and parking-assist system controls the motion of the vehicle to follow a collision-free path. In this study, a motion control algorithm using Fuzzy inference is proposed to track a maneuvering clothoid parallel path. Simulations are performed under SIMULINK environments using MATLAB and CarSim for a vehicle model. As the vehicle model in MATLAB a bicycle model is used including lateral dynamics. The simulation results show that the path tracking performance is satisfactory under various driving and initial conditions.

The researches for autonomous vehicle have been implemented in many studies, but most studies were confined to the lane fol1owing and changing. This paper addresses a problem of autonomous lane following parking a nonholonomic vehicle. The algorithm for image processing by the hough transform and controlling a steering angle and speed to park a nonholonomic vehicle is developed. The developed system which integrated the control algorithm for parking and vision algorithm for line traction tested with RC car and verified by the performance of the detection of parking area and the reactive parking without collisions.

The purpose of this study is recognized the problems of parking and parking demand, supply and operation of the control etc. It is to provide an alternative for the overall parking problem. Parking problem occurs because there is not enough parking spaces. In order to solve the parking problem of Chil-gok 1 residential development district, this study propose making use of a road parking lot establishment and the school playground and the public facilities construction parking lot. But it is the methods which are short-term. A fundamental solution method is Levying garage option on car buyers. It is system to apply a law for establishing garages to all of vehicles.
