It　was　assumed　that　the　travel　demand　density　is　uniformly　distributed　along　the　corridor　in　a　monocentric　city　with　railway　and　main　roads　and　the　railway　has　the　continuously　distributed　stations　to　analyze　the　traveller　park　and　ride　demand　distribution　characteristics.　A　hierarchical　disaggregated　model　was　proposed　considering　the　traffic　mode　choice　including　the　car,　the　railway,　the　park　and　ride,　and　the　parking　lot.　By　the　method　of　stochastic　continuum　equilibrium　model　in　combination　with　numerical　examples,　it　was　found　that　the　park　and　ride　demand　appears　highest　at　a　certain　distance　range　and　decreases　with　the　increase　of　the　transfer　time.　The　park　and　ride　lots　attract　some,　although　relatively　small　backward　ride　demand.　Large　park　and　ride　demand　comes　from　the　peripheral　of　the　city　and　the　demand　intensity　decreases　with　the　increase　of　the　distance　to　the　lots.　When　the　parking　lot　capacity　is　restricted,　the　park　and　ride　traveller　may　change　the　transfer　lot.　These　results　provide　a　reference　for　the　planning　and　construction　of　the　park　and　ride　facilities.
