In　order　to　improve　the　reliability　of　urban　road　network　operation　evaluation,　the　road　network　regional　Partition　methods　were　launched　in　this　paper.　The　geographic　grid　was　introduced　first,　and　a　4-level　road　network　model　was　defined.　Then,　the　spatial　analysis　based　urban　road　network　division　method　was　proposed　by　analyzing　the　characteristics　of　road　network　operation.　This　method　can　reflect　the　influence　between　adjacent　regional　units,　and　improve　the　reliability　of　urban　road　network　division.　Finally,　this　research　took　a　certain　area　in　Beijing　as　a　case　study,　and　divided　the　road　network　as　several　regional　units.　Macroscopic　evaluation　result　shows　that　it　is　effective　for　scientifically　describing　the　road　network　operation　status.
