This　paper　attempted　to　study　the　characteristics　of　silt　loading　on　various　types　of　roads　and　seasonal　variation　of　silt　loading　on　typical　roads　in　Fengtai　District,　based　on　the　vehicle-mounted　navigation　monitoring　system.　We　discussed　the　changing　trend　and　related　causes　of　the　road　traffic　flow,　silt　loading,　and　fugitive　road　dust　emission　for　the　different　loop　roads,　and　analyzed　the　spatial　distribution　of　silt　loading　and　fugitive　road　dust　emission　using　ArcGIS　software.　The　results　showed　that　the　silt　loading　and　fugitive　road　dust　emission　factors　in　various　types　of　roads　should　be　ranked　as:　branch　road＞minor　road＞main　road＞expressway.　The　traffic　flow　was　inversely　related　to　the　silt　loading　on　the　road　and　the　emission　intensity.　The　annual　fugitive　dust　emissions　of　PM2.5,　PM10　and　TSP　on　the　roads　within　Fengtai　District　were　1824,　7539,　39274　t•a-1,　respectively.　In　terms　of　the　spatial　distribution　of　annual　PM2.5　emissions,　the　grid　emissions　within　the　3rd　ring　road　were　largest,　followed　by　the　roads　between　the　3rd　and4th　ring,　and　the　fugitive　dust　emission　per　unit　area　on　the　roads　outside　the　6th　ring　was　the　smallest.　The　traffic　volume　and　emissions　per　unit　area　were　ranked　as:　roads　within　the　3rd　ring＞roads　between　the　3rd　and　4th　ring＞roads　between　the　4th　and　5th　ring＞roads　between　the　5th　and　6th　ring＞roads　outside　the　6th　ring.　The　annual　silt　loading　on　these　roads　were　0.67,　0.73,　0.76,　0.80,　0.79　g•m-2,　respectively.　©　2021,　Science　Press.　All　right　reserved.
