![]() ![]() Effective setting of guiding signs would improve operation efficiency of the public transport system, or it might hinder the normal operation of metro stations, and further lead to serious traffic accidents. Therefore, its operation efficiency will affect the whole urban public transportation system. In China, metro stations provide service to a large number of passengers to maintain normal running of cities in a routine day. The research results of this paper can provide theoretical support and technical guidance for the optimal establishment of pedestrian guiding signs in metro stations with massive passenger flow.Īs an important form of rail transit, metro has become the main mode of public transit in urban transportation. Finally, the key points of optimal setting of guiding signs in different regions and different periods were obtained according to the result analysis of the experiment. With the increase of crowd density, the change of walking speed of pedestrians can be represented by a unimodal curve. Moreover, pedestrian speed at the stairs adjacent to the platform is higher than that at the stairs not adjacent to the platform. The walking speed of pedestrians in closed-type passageways is higher than other types. After analyzing the characteristics of pedestrians’ microscopic behavior in metro stations, otherness of walking speed was found out among pedestrians in different types of passageways. In this paper, the microscopic behavior characteristics data of pedestrians at different positions in typical metro stations were collected through pedestrian tracking experiments. However, perspectives from humanization of pedestrian guidance signs such as pedestrian behavior needs and pedestrian cognition were seldom proposed. Currently, most studies on guiding signs focus on architecture, aesthetics and simulation. ![]() In metro stations with massive passenger flow, the rationality of sign setting would exert distinct effects on the efficiency of passenger flow. The Standard Highway Signs book can be purchase from the US Government Printing Office and the American Traffic Safety Services Association through the web sites listed above.In the metro operation environment, guiding signs provide direction and route conversion instructions to pedestrians. Hard copies of the MUTCD can be purchased from the American Association of State Highway and Transportation Officials ( ) the Institute of Transportation Engineers ( ) the American Traffic Safety Services Association ( ) and the US Government Printing Office (). This web site also contains information on standard lettering used on highway signs and pavement markings and on highway sign color specifications. Both of these books are available in electronic format online at. Dimension drawings for signs can be found in the Standard Highway Signs book. ![]() Standards for the sign design and application of the signs shown here as well as for other traffic control devices are contained in the Manual on Uniform Traffic Control Devices (MUTCD). On the navigation bar under Knowledge, select Sign Shape/Color. Test your Sign IQ by taking the interactive shape and color quiz available on the web at. The illustration below shows how the shape and color of a sign indicate the nature of the message. A circular sign warns of a railroad crossing. Rectangular signs with the longer direction horizontal provide guidance information. Additional regulatory signs are octagons for stop and inverted triangles for yield. Traffic regulations are conveyed in signs that are rectangular with the longer direction vertical or square. Sign shape can also alert roadway users to the type of information displayed on a sign. A white background indicates a regulatory sign yellow conveys a general warning message green shows permitted traffic movements or directional guidance fluorescent yellow/green indicates pedestrian crossings and school zones orange is used for warning and guidance in roadway work zones coral is used for incident management signs ** blue indicates road user services, tourist information, and evacuation routes and brown is for guidance to sites of public recreation or cultural interest. The use of red on signs is limited to stop, yield, and prohibition signs. The color of roadway signs is an important indicator of the information they contain. Familiarity with symbols on traffic signs is important for every road user in order to maintain the safety and efficiency of our transportation facilities. Symbols provide instant communication with roadway users, overcome language barriers, and are becoming standard for traffic control devices throughout the world. Roadway signs in the United States increasingly use symbols rather than words to convey their message. ![]()
