Traffic Technology Drives to Clear the Road
交通技术让道路畅通无阻
The world’s leading traffic technology scientists will meet in Paris this week to find a way of easing congestion on the roads and developing the auto mated highways of the 21st century.
世界权威的交通技术专家本周将在巴黎聚会，商讨解除道路拥塞和发展21世纪自动公路的问题。
Nearly 2,000 delegates are expected to attend the Four-day event,which begins on Wednesday．It will be addresd by Dr Brian Mawhinney，the transport cretary，as well as the heads of veral Car companies．
大约有2000名代表要参加这次将在星期三召开的为期四天的会议。交通大臣Dr. Brian Mawhinney和几个汽车公司的头脑将发表讲话。
Among the technologies on show will be vehicle—-to--roadside communication links to provide drivers with up to date traffic information；in-ground and overhead nsors that monitor the level and volume of traffic；low-cost satellite receivers that allow drivers to pinpoint their position anywhere on earth；and in-vehicle navigation systems able to guide drivers along the least congested streets．
参展的技术有：为驾驶员提供最新的交通咨讯的车辆与路边通讯的联接装置；监视交通状况 和流量的地下和高架的传感器；为驾驶员提供他们在地球任一地点的准确定位的廉价的卫星接受器；及能够引导驾驶员选择最畅通道路的车内导航系统。
“This will be the first event of its kind where the world’s leading transport rearchers will be able to discuss new technological developments with road ur groups and highway authorities，”says Eric Sampson，chairman of the main organizing committee,and deputy chief scientist at the Department of Transport in London．
Eric Sampson, 伦敦交通部首席科学家代表和本次会议总组织委员会主席说： “这将是世界上 顶级交通专家与道路使用人员和公路管理当局首次一同讨论新技术的发展问题。 所讨论
的技术包括可以马上实施的现成技术，以及在近几年内可以实施的其它技术，还有下 一世纪将要制造出的“完全的自动汽车”所要更未来的系统技术。
The technologies under discussion include systems that are ready for implementation，others that will be introduced within a few years,and more futuristic systems that will be ud in the next century to create ‘fully automatic’ cars．
讨论的技术包括系统，准备实施，其他人将推出的几年内，和更多的未来系统将在下个世纪创造的全自动车。
Road tolling technology is a top priority，especially in Britain．Several systems will be tested as part of the electronic tolling trials starting on the M3 motorway near Basingstoke next spring．As well as debiting drivers for using the roads，the same tolling technology could be ud to cut traffic．
道路收费技术是最优先的技术，在英国更是如此。明年春天（next spring）在Basingstoke
近的M3高速公路上作为电子收费试验的一部分，将进行几个系统技术的测试。就象向道路的使 用司机收费一样，同样是收费技术但它可以降低交通拥挤。
The systems to be shortlisted by the Department of Transport in the next few months will u microwave nsors on overhead gantries——or cellular mobile phone links to detect every vehicle travelling on theroad and then debit a smart card on its windscreen．
在接下来的几个月里由交通部选定的候选技术将在跨路钢架使用微波传感器----或移动通讯 联接----来检测在路上行驶的每一台车辆，然后从贴在车辆挡风屏上的智能卡上收取相关费用。
Once in place, the same communication links could be ud to nd other uful information between vehicles and the roadside，bringing the ‘smart’ highway clor to reality． For instance，a trial in Portugal enables drivers to book a parking space in the center of Lisbon while they are still driving along an approach road．
只要此项技术得以实施，此项通讯连接也可以用于传递车辆和路旁间其它有用的信息，使得智能公路更接近于现实。例如，葡萄牙所进行的一项试验使司机可以在驶往的路上预定里斯本市 中心的停车位。
In-vehicle route-guidance systems are already coming into u．In Japan，more than 500000 cars have a route,guidance system on their dashboards．In Britain，guidance systems made by Sony，Panasonic，Philips and Bosch are expected to be available from1996．
车内路线导航系统已经开始使用了。在日本，多达50万辆车在其仪表板上有车内路线导航 系统；在英国，由Sony、Panasonic、Philips和Bosch公司制造的导航系统有望在96年上市销售。
With the more advanced versions，a comprehensive digitized road map of the country is stored on a CD-ROM in the car boot and contains the location of every known road，junction and tourist attraction．
随着技术的不断改进，储存于CD—ROM内，放在汽车后盖里的更综合的国家数字地图将会 出现，它将含有每一条所知道的道路、交叉路口和旅游胜地的信息。
Drivers simply input their destination (using a simple Qwerty or touch-pad keyboard) before beginning their journey，and follow directional arrows on a small screen as they drive．
司机只要在开始他的行程前使用(QWERTY keyboard n. 〈计〉标准键盘，英文键盘)标准键 盘或触摸式键盘输入目的地，遵循小屏幕上的方向箭头的指引驾驶就可以了。
As each system also receives ‘live’ traffic updates from a special radio channel or roadside-to-vehicle cellular communication link. vehicles will automatically be routed along the least congested roads．
由于每一个系统也能从特殊的广播频道或路旁-----与车移动通讯系统接受不断更新的实况交通信息，车辆可以自动选择最畅通的路线行驶。
In the long term，cars will be designed to communicate directly with the highways．Vo
lvo has demonstrated a system in which speed limit signs on the roadside are able to take over a car’s controls and reduce the vehicle’s speed automatically．
