ABSTRAK Nitrogen dioxide gas is one of the air pollutants frosm transport sector, this gas formed during combustion of fuel at high temperatures that occur in vehicle engine. The existence of a queue of vehicle at highway gate can lead to accumulation and increased concentration of NO2 ambient air. With increasing concentration of NO2 in the air around the highway can decrease the health of the worker and the environment surrounding the highway. The change of value of NO2 concentrations at highway influenced by the number of length of queue of vehicles, as well as meteorological factor such as wind speed and wind direction. The number and length of vehicle queues are related an dame direction, and the meteorological factor are wind direction and speed that most determine the concentration of NO2, where the valuecorrelation is opposite direction. The most influential type of vehicle what increasing NO2 concentration is a type of Heavy duty vehicle like as truck and bus. Kata Kunci: Nitrogen Dioksida, length of queue, number vehicle and meteorological factor.
