Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Figure 1 to Figure 2 The reference numerals in the figure are: microprocessing unit 101; GPS module 1; GPRS module 2; serial port communication module 3; direction selection keyboard 4; car model selection keyboard 5; liquid crystal display module 6; lights9.

[0026] Such as figure 1 Shown, a kind of traffic investigation instrument comprises power supply 8, self-inspection lamp 9, microprocessing unit 101, input unit, GPS module 1 and GPRS module 2, and described input unit, GPS module 1 and GPRS module 2 are respectively connected with described The microprocessing unit 101 is connected.

[0027] After the power supply 8 is powered on, if the CPRS module 2 is detected, the self-test light 9 will flash once every five seconds, otherwise the self-test light 9 will flash at intervals of 0.2 seconds, which means that the battery volta...

Abstract

The invention relates to traffic survey, in particular to a traffic survey instrument and a traffic survey method in the traffic survey. The traffic survey instrument comprises a micro-processor unit, an input unit, a GPS module and a GPRS module, wherein the input unit, the GPS module and the GPRS module are connected with a micro-processor unit respectively. The invention also provides a traffic survey method. The traffic survey instrument and the traffic survey method have the advantages of monitoring whether traffic survey personnel surveys on time at a survey place and verifying whether the survey data is accurate in real time.

Description

technical field [0001] The invention relates to traffic survey, in particular to a traffic survey method in traffic survey. Background technique [0002] The investigation and analysis of traffic volume is a research topic in traffic engineering. In practical work, highway traffic volume is an important index reflecting the use status of highways and the extent to which highways meet the needs of automobile transportation. Traffic volume survey data are widely used in road maintenance management, road use process, road network planning, road construction preliminary work, route design, and later economic value evaluation. It is an indispensable basis for engineering design of traffic facilities, and it is also an indispensable basis for formulating maintenance plans and formulating traffic management measures. Therefore, doing a good job in traffic volume survey and statistics is directly related to the modernization of highways and the scientific management of highways, an...
