The outdoor and indoor air quality surrounding highway have been measured, and the study on the design of the booth shape and the air-conditioning system also has been carried out. For the first step of the work, the air quality at the Seoul tollgate on the Kyeong-bu highway was monitored over a year. The measured indoor air quality shows seasonal average concentration 85.6-92.1ppb of >;$NO_2$and the $SO_2$and CO lower than the EAQS(Environmental Air Quality Standards). The measured TSP concentration was much higher than the EAQS. In conclusion, there is necessity to improve the working environment of the tollbooths on highways, and the current air-conditions need to be modify for the purpose. In the process of modifying the air-conditioning system, particulate pollutants needs to be considered processing and the priority needs to be put on the booths for big vehicles.
