A Risk Assessment Method for Fine Particle Exposure Based on Bus IC Swipe Card System

Abstract

The invention discloses a fine particle exposure risk assessment method based on a bus IC card swiping system. The IC card swiping system includes a bus center IC card management system, a bus front door boarding card swiping machine and a bus station platform alighting card swiping machine; The card swiping machine for getting off the bus at the bus station and the card swiping machine for getting on the bus at the front door are wirelessly connected to the IC card management system of the bus center; the fine particle exposure risk assessment method based on this system includes the identification of the card swiping site for S1 bus passengers, Judgment of bus passengers’ alighting and card-swiping stations, calculation of passenger density in S3 bus compartments, and risk assessment of passenger group exposure in S4 bus compartments. The invention is easy to operate, accurately calculates the passenger density and group exposure risk level in different sections of the bus route, and comprehensively and accurately reveals the groups of passengers in the carriage facing fine particle pollution from multiple angles and levels during the bus operation. Exposure risks are of great significance to the assessment of bus operating environment and have good social benefits and market application value.

Description

technical field [0001] The invention relates to the technical field of public transportation, in particular to a fine particle exposure risk assessment method based on a bus IC card swiping system. Background technique [0002] Bus travel plays a very important role in urban traffic travel. Bus travel card swiping records are the basic data for urban bus network planning and management, and can provide important data support for bus network optimization and travel forecasting. [0003] The existing bus card swiping system is one-time card swiping. Based on the existing bus card swiping system, it is estimated that there are deficiencies in the boarding stations for bus travel: when there are too many vehicles queuing up at the bus station, non-standard parking causes vehicles to fail. Passengers get on the bus and swipe their cards ahead of time when they arrive at the station, which leads to the estimation of the passenger boarding station in advance; when the distance betw...

[0003] The existing bus card swiping system is one-time card swiping. Based on the existing bus card swiping system, it is estimated that there are deficiencies in the boarding stations for bus travel: when there are too many vehicles queuing up at the bus station, non-standard parking causes vehicles to fail. Passengers get on the bus and swipe their cards ahead of time when they arrive at the station, which leads to the estimation of the passenger boarding station in advance; when the distance between two adjacent stations is short, the boarding station is clustered on the previous bus in the direction of the line based on time clustering The boarding station is estimated to be ahead of time; when the flight attendant swipes the card with the POS machine, due to the large number of boarders, the card is swiped before entering the next station. next stop

Existing problems: (1) The card swiping mode is incompatible with the "card swiping on board" mode commonly used in the bus system, and the position of the card reader on the bus needs to be changed; (2) There is no one on the platform before passengers board the bus Guidance and supervision may cause passengers to forget to swipe their cards. At the same time, when passengers are eager to get on the bus that is about to leave the station, they may not have time to swipe their cards at the platform. These two situations cannot guarantee that passengers can swipe their cards smoothly before getting on the bus; You need to swipe your card in the bus. When the bus is crowded, you may swipe your card ahead of time or you may not be able to swipe your card. If you cannot finish swiping your card before arriving at the station due to the congestion in the bus, the bus may have to wait at the platform for a long time

[0005] Under the background of advocating and pursuing low-carbon and healthy travel, there is still a lack of research focusing on the group exposure risk of fine particle pollution for passengers in the bus travel process
