With　the　development　of　wireless　charging　technology,　charging-while-driving　now　becomes　possible.　In　this　paper　we　propose　a　model　to　optimize　the　location　of　the　wireless　charging　lanes　(WCL)　by　taking　into　account　their　effects　on　road　capacity　and　traveler＇s　route　choice.　The　model　is　formulated　as　a　nonlinear　programming　problem　and　solved　by　a　linearization　method.　A　new　method　is　developed　to　reduce　the　maximum　error　in　the　linearization　process.　The　model　and　solution　method　are　tested　on　Nguyen-Dupuis　and　Sioux　Falls　networks.　The　numerical　results　show　that　relatively　high　charging　power　and　reasonable　budget　are　necessary　to　recover　the　investment　when　charging　lanes　are　deployed　on　road　network.　It　is　also　demonstrated　that　the　impacts　of　WCL　on　road　capacity　drop　and　travelers＇　route　choice　are　not　negligible,　and　should　be　considered　in　the　determination　of　WCL　location.
