交通标志

Yesterday 18:30 or so, this reporter went to the bridge four corners, looking, saw the broad formation of asphalt pavements from the foot of a cross, City of Victoria main road from the green belt has been completed, the white traffic stripe, green traffic signs are two directions to the North-South extension, the people are transported to tall deodar cedar and dark green of the turf, And more beautiful around the overpass.

昨天下午6时30分左右，记者来到四阜桥上，放眼望去，只见宽阔平整的柏油路面从脚下穿越而过，四环主路中间隔离带的绿化已经全部完成，白色的交通标线、绿色的交通标志正在向南北两个方向延伸，工人们正在运来高大的雪松和碧绿的草皮，把立交桥周围装点得更加美丽。

In this paper,three types of traffic signs (i.e.warning sign,interdictory sign,and indicatory sign, totally 116 signs) are further classified by the classification function of BP network.

为了安全驾驶和有效导航，交通部门在公路道路上设置了各类重要的交通标志，作为道路交通的有关信息提供给驾驶员。

The trees and other plants along both sides of the road or along the median strip, as well as the installed advertisement boards and pipelines, etc., shall be kept a necessary distance away from the traffic facilities, and shall not shelter road lamps, traffic signal lamps or traffic signs, or impede the safe range of visibility, or affect the passage.

道路两侧及隔离带上种植的树木或者其他植物，设置的广告牌、管线等，应当与交通设施保持必要的距离，不得遮挡路灯、交通信号灯、交通标志，不得妨碍安全视距，不得影响通行。

Based on large humors of driving experiments with EMR-8B as test apparatus, the influence of lighting condition to traffic sign visibility distance is studied under different driving speeds, then the relativity among risibility distance, driving speed and lighting condition is analyzed.

将眼动仪EMR-8B应用到交通安全研究领域中，从影响交通标志视认性的外部因素出发，以大量的现场行车实验为研究手段，探讨了在不同行车速度下，光线条件对交通标志可视距离的影响。

Geographical information system ; urban road network ; traffic sign and marking ; traffic resources analysis and real-time information

地理信息系统；城市道路网；交通标志标线；交通资源分析和实时信息

With the development of highway traffic in our country,the setting of traffic signs becomes more and more normative,however,there are still lots of problems when installing at secondary road.

随着我国公路交通事业的发展，交通标志的设置日趋规范，但在二级公路的标志设置中仍然存在着许多问题。

Therefore,it discusses the categories of signs,fonts of the board and installation location aiming at the secondary road in detail based on the understanding of new GB.

因此有必要通过对国标的理解，针对二级公路常用的交通标志种类、版面字高和标志设置位置等进行相关的分析研究。

Article 28 No entity or individual may discretionally set up, remove, occupy or damage any traffic signal lamp, traffic sign or traffic line marking.

第二十八条任何单位和个人不得擅自设置、移动、占用、损毁交通信号灯、交通标志、交通标线。

Safety Facilities: traffic lights, traffic signs, solar sign series, roadblocks lights, electronic warning light, road crossings deceleration zone, Wheel Locator, safety alerts cone, electronic flash road cone, crossing pillars, isolation column, Traffic precursor, reflector retaining angle, wide angle lenses, water horse, holding the command, boldface warning, railroad crossing shockproof pad, rail pads, rubber bridge stretching devices, rubber, such as reflective vests.

交通安全设施：交通信号灯、交通标志、太阳能标志系列、路障灯、电子警示灯、公路道口减速带、车轮定位器、交通安全警示锥、电子闪光路锥、道口立柱、隔离柱、分道体、反光护角、广角镜、水马、指挥捧、警示横杠、铁路道口防震垫、钢轨垫片、橡胶桥梁伸缩装置、橡胶止水带、反光背心等。

Based specialized, generalized and visualized basic geographical information, it collects many information, such as detected video, traffic control signal, traffic peccancy, policemen distributing, traffic target, stopping position and capacity, to general manage and analyze. The primary visualized decision information including traffic flux, bus speed, traffic density, accident of real-time cities main road, are provided to traffic manager so that they respond rapidly, and some of them could be transformed to traffic inducing screen through network.

系统设计目的：建成一个基于网络环境的实时的、可视化的交通管理地理信息系统服务平台，它以专业化的、综合性的、可视化的基础地理信息为基础，综合集成现有系统，将监控视频，交通控制信号、交通违章监控等实时动态信息以及警力分布、交通标志、停车场位置及容量等各种数据采集起来，进行集中管理和分析，为交通管理者提供实时的城市各主要道路的交通流量、车速、交通密度、事故发生情况等可视化初级辅助决策信息，以便交通管理人员做出快速响应，也可将部分信息通过网络主动发布到交通诱导屏。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
