Problems solved by technology

[0002] There are many problems in the current traffic signs of the expressway, such as inconsistent and incoherent codes of toll stations; signs of some ramps and interchanges block each other; lack of relevant orientation indicators in location signs; insufficient number of direction signs; variable sign setting positions Its function is limited, and the utilization rate is low; the guide signs lack systematicness and coherence; the lack of instructions for adjacent national and provincial roads; the content of expressway service area signs is single, which brings a lot of inconvenience to drivers

Embodiment

[0052] Embodiment: a kind of setting method that is used to optimize the traffic sign of expressway network is characterized in that it comprises the following steps:

[0053] (1) Digitally code the entrance and exit, including:

[0054] ① Digitally code the entrances and exits of ordinary ramps, which are divided into urban radial codes and transit expressway codes. Among them, the urban radial codes are coded sequentially from the No. 1 entrance and exit along the outward direction of the central urban area; the so-called transit expressway codes According to the national road network planning, the ramp entrances and exits of each province and city are uniformly coded according to the direction of the expressway, and the first entrance and exit within the boundary of each province and city are sequentially coded according to the direction of the expressway.

[0055] ② The expressway and expressway interchanges are not coded, and a fixed expressway interchange sign symbol plu...

Abstract

A method for disposing traffic signs to optimizing highway network comprises following steps: (1) encoding the inlets and outlets digitally; (2) digitalizing related national and provincial road level codes; (3) optimizing outlet signs; (4) optimizing inlet signs; (5) optimizing locus direction signs; (6) optimizing vehicle distance confirming signs; (7) optimizing locus distance signs; (8) optimizing dynamic changeable message signs integrated application; (9) optimizing service area signs; (10) optimizing tourist area signs; (11) adding alarm and succor telephony signs; (12) disposing solar energy warning lamps; and (13) disposing road maintenance construction safety signs. The advantages of the invention are: (1) both the quantity and the quality of traffic signs are provided; (2) humanization; (3) highway segments and areas form a complete set integrally; (4) fixed signs and variable signs cooperate; (5) traffic channeling and traffic controlling of highway ramp inlets and outlets and intercommunicating interchange areas between highways are intensified; (6) humanized traffic signs are provided for road users; (7) reasonable positions and sizes of traffic signs are provided.

Description

(1) Technical field: [0001] The invention relates to a method for optimizing traffic signs, in particular to a method for optimizing the setting of traffic signs on expressway networks, that is, a method for setting traffic signs for optimizing expressway networks. (two) background technology: [0002] There are many problems in the current traffic signs of the expressway, such as inconsistent and incoherent codes of toll stations; signs of some ramps and interchanges block each other; lack of relevant orientation indicators in location signs; insufficient number of direction signs; variable sign setting positions Its function is limited, and the utilization rate is low; the guide signs lack systematicness and coherence; the lack of instructions for adjacent national and provincial roads; the content of expressway service area signs is single, which brings a lot of inconvenience to drivers . (3) Contents of the invention: [0003] The purpose of the present invention is t...
