Abstract

The invention is a portable traffic information acquisition system, which consists of PDA and GPS receiver. The PDA sets up a database and interface to inter-communicate with computer. The GPS and PDA are inter-connected. PDA gets roads basic attribute information from computer, then PDA automatically generate electronic survey sheets for field data collection according to the information. PDA as a handheld device is taken to the scene for data collection. The collected traffic information inputs to the database in PDA directly, meanwhile GPS receiver transmits the scene position information to PDA. PDA then transmits the data that have been in the database to computer for the follow up of data processing, analysis and store.

Description

technical field [0001] The invention relates to the field of physics, in particular to the measurement and recording technology of traffic information, in particular to a portable traffic information data collection system. Background technique [0002] The collection of traffic information data is of great significance for theoretical research, traffic planning, traffic management or traffic evaluation. In the prior art, collecting traffic information data through handwritten records is still a common and practical technical means. The way of handwritten records needs to prepare paper survey forms in advance, and then write and record the data on paper surveys during on-site data collection. Finally, file the paper survey form or manually input the data in the paper survey form into the electronic computer for storage. However, because the object, content, location or purpose of each traffic survey is different, the form of each traffic survey is also different. Even a si...
