Due　to　urban　construction,　engineering　transport　vehicles　are　gradually　increased　on　roads,　which　might　speed　up　traffic　accident　risks.　To　investigate　the　influence　of　urban　construction　on　traffic　accidents,　this　paper　adopted　1977　traffic　accidents　of　engineering　transport　vehicles　and　220　engineering　construction　projects　for　correlation　analysis.　First,　considering　three　degrees　(Major,　Ordinary　and　Minor)　of　accidents,　the　spatial　autocorrelation　test　of　engineering　transport　vehicle　accidents　is　carried　out　by　using　spatial　econometric.　Then　to　further　evaluate　and　analyze　the　spatial　regression　model,　the　optimal　model　is　selected　to　analyze　the　spatial　influence　of　the　floor　area　of　different　types　of　engineering　construction　projects　on　the　accidents　of　engineering　transport　vehicles.　The　results　show　that　the　accident　of　engineering　transport　vehicles　itself　is　spatially　dependent,　that　is,　the　higher　the　severity　of　the　accident,　the　more　concentrated　it　is　in　space,　and　there　is　a　significant　spatial　positive　correlation　with　engineering　construction　projects.　And　the　floor　areas　of　synthetic　land,　residential　land,　commercial　land　and　land　for　roads　and　transportation　facilities　have　significant　spatial　effects　on　engineering　transport　vehicle　accidents,　and　the　indirect　effects　are　also　concerned.　The　increase　of　floor　area　of　roads　and　transportation　facilities　is　more　likely　to　induce　accidents　of　engineering　transport　vehicles.　For　every　10,000　square　meters　of　the　floor　area　of　roads　and　transportation　facilities,　there　are　12.66　accidents　of　engineering　transport　vehicles　in　the　region　and　its　neighboring　areas.　©　2022　Elsevier　Ltd
