In an endeavor to solve the parking management issue,different technologies have been developed in various parts of the world and research was conducted to develop efficient parking technologies.The places looked at in this section include cape Town International airport,Cavendish shopping mall in Claremont (Cape Town) and other places in the world such as central London parking bays.
Some Parking System Technologies.
A number of technologies have been deployed in the endeavor to solve the parking problem.While some parking solutions are deployed as stand-alone technologies in some situations,in other situations multiple technologies are combined to achieve a given goal.These technologies include (1) Camera-based sensor technology (2) infrared sensor technology and ultrasonic sensor technology.
1.Camera-based sensor technology
Access control systems have been developed and installed in various parking lots.At the airport in Cape Town,an access control point was put in place.It works in such a way that a driver requests for a ticket at the entrance of the parking by pressing a button.When a ticket is issued,the driver is granted access to enter the parking bay [5].The ticket issued is marked with a code that records the time of entrance to the bay.At the time of exit,the driver has to pay for the time the car spent in the bay.Payment is done by inserting the ticket in another machine which reads the code on the ticket and calculates the amount of time spent.Then a parking fee is charged according to the time spent.Sensors are used at entrance and exit points to keep track of the cars in and out.A display board (variable message sign) is used at the entrance to show whether the bay is full or still has unused slots.This technology helps with the management of payment of use of the parking bays.It also gives users a general idea of the number of available parking slots by displaying a message like “level 1 full”.However,it doesn’t give much help to the driver in finding an exact parking space in the shortest time
possible nor allows localization of his car in a given parking spot using for example Radio
Frequency Identification (RFID) technology.

在努力解决停车场管理问题中,世界各个地区都已在研发不同的技术,各种不同的研发机构也已成立以研发有效停车管理技术.这些机构主要着眼于这些地区,包括开普敦国际机场,在克莱门特的板烟购物中心(开普敦)和其它世界各地如伦敦市中心的停放点.
一些相关的停车系统技术
一系列的技术已经在部署为了努力解决停车难的问题.虽然在某些情况下,有些停车方案都部署是独立的,在另一些情况下,则多项技术结合起来,以实现指定的目标.这些技术包括(1)以照相原理为基础的传感技术（2）红外探测技术和（3）超声传感技术.
1.以照相原理为基础的传感技术
存取控制系统已被开发和安装在各种各样的停车场.在开普敦的机场,一个存取控制点被放在了适当的位置.它是这样运行的,汽车用户在入口处按下按钮,系统将会自动输出一张据.当一张票输出的时候,该名汽车用户是准许进入停车场泊车的.这张票设置了一些代码以记录进入停车场的时间.当出去的时候,汽车用户必须支付与停车时间相应的停车费用.所支付的费用将会由另一台机器根据所输出的票据所记录的时间并计算出停留的时间,以算出相应的费用,然后停车费则由相关的停车时间来计算.传感器设于入口和出口处,用于扫描汽车进入和出去时的点.一种显示板(可变信息标志)用于入口处,显示出停车位已满或仍有闲置的停车位.该技术可以帮助公司管理层的支付方式的停放点的使用.同时,也通过诸如“一等停车位已满”这类信息告诉汽车用户大致的可用的闲置停车位.然而,它并不能帮助汽车用户们在短时间找到一个精确的空闲的停车位,也不允许他利用例如广播射频识别(RFID)技术在停车场对其汽车进行定位.
