Problems solved by technology

However, the above method uses the on-board Wi-Fi of the bus for detection, resulting in the continuous movement of the distance standard range, which cannot clean up a large amount of interference data that exists during the movement of the bus. greatly increased the error

Embodiment Construction

[0034] Below in conjunction with the embodiment shown in the accompanying drawings the present invention will be further described

[0035] The invention proposes a method for collecting and analyzing passenger flow OD (boarding station and disembarking station) data based on the combination of station Wi-Fi hotspot detection and bus GPS positioning. This data collection method is based on the Wi-Fi+Bluetooth detection equipment fixedly placed at the station, which can detect the connection and disconnection of wireless devices, and then obtain the MAC address of the passenger's mobile terminal and the corresponding connection and disconnection time. By combining the real-time location of the bus recorded by the GPS recorder and the arrival time information, the MAC address is matched with the bus entry and exit time as the standard, so as to realize the O-D collection and analysis of the passenger flow of the bus line, figure 1 It is a schematic diagram of the internal operat...

Abstract

The invention provides a bus passenger flow acquisition and analysis method based on stop WiFi and an onboard GPS. The method comprises that a stop Wi-Fi detection device acquires the MAC address information of mobile terminals held by users in a detection range near each stop of a bus and the onboard GPS obtains the real-time position of the bus; removing interference data according to a conformity relation between the getting-on / off time of passengers and the arriving / leaving time of the bus to obtain the user information of get-on passengers and the user information of get-off passengers ateach stop, and calculating the passenger flow of each stop. The method, based on the Wi-Fi detection devices at fixed locations of bus stops and by means of space-time dual filtering in combination with Wi-Fi detection and onboard GPS positioning, eliminates the sudden interference that cannot be processed by the onboard Wi-Fi detection and greatly reduces the errors. With increasing coverage ofWi-Fi APs, the accuracy of the system is also improved increasingly.

Description

Technical field: [0001] The invention provides an intelligent traffic management method, in particular to a method for collecting and analyzing bus passenger flow based on site WiFi and vehicle-mounted GPS, using R language and ArcGIS for data screening and ArcGIS projection for visual presentation. Background technique: [0002] At this stage, with the increasing contradictions in urban traffic, developing smart public transport systems and improving the operating efficiency of public transport systems have become important means to alleviate urban traffic congestion. The research and analysis of bus passenger flow has gradually become a research hotspot in the field of transportation. [0003] Existing bus passenger flow estimation methods include IC card detection method, Wi-Fi identification and other methods. The bus IC card technology is simple and mature, with a large amount of collected information and has been applied in many cities, and the number of bus passengers...
