Vissim4.3之API/SDK编程;Vissim编程;

你看到的这个文章来自于http://www.cnblogs.com/ayanmw

vissim4.3 是德国PTV公司的一款微观交通模拟软件.

其可以模拟道路车辆,红绿灯运行,可以模拟3D的景象.我这里直说2D

在2D的一段道路上,有车在运动,如何获取车子的坐标信息呢??

根据Vissim文档,可以通过Vissim的COM编程接口进行编程,COM接口可以使用VB(s)/VC/Python/等所有支持COM的语言编程.

其步骤是:1 安装vissim软件,4.3很特殊,有个破解的license,但是要修改时间为2008年,具体可以到 智能交通 论坛下载.

2.安装VB,如果使用VBS可直接开始编程.我使用了VB6进行编程.(没办法,虽然老,但是无法替代啊.)

3.新建立VB工程,默认的exe就可以.

然后在工程->引用 ->浏览 添加 C:\PTV_Vision\VISSIM430\Exe\vissim.exe 这个vissim的可执行文件(其也是COM Server的组件)

然后 整一个按钮,双击开始添加代码

Dim vis     As vissim
Dim SIM     As Simulation
Dim vehins  As VehicleInputs
Dim vehin   As VehicleInput
Dim vehicles As vehicles
Dim vehicle  As vehicle

   Set vis = CreateObject("VISSIM.Vissim")                                     'NEW Vissim
    vis.LoadNet "C:\PTV_Vision\VB COM for VISSIM\Demo_VISSIM_CrossTraffic_INP\crossTraffic.inp"
    Set vehins = vis.Net.VehicleInputs
    Set vehicles = vis.Net.vehicles
    Set SIM = vis.Simulation
    For i = 1 To vehins.Count
        If True Then
            Set vehin = vehins(i)                                               'or vehins.Item(i)
            msgbox "VeHins.Count=(" & vehins.Count & ");i =" & i
            msgbox "VeHin.name=" & vehin.Name & vbCrLf _
            & "VeHin.ID=" & vehin.ID & vbCrLf _
            & "VeHin.AttValue(TIMEFROM)=" & vehin.AttValue("TIMEFROM") & vbCrLf _
            & "VeHin.AttValue(TIMEUNTIL)=" & vehin.AttValue("TIMEUNTIL") & vbCrLf _
            & "VeHin.AttValue(VOLUME)=" & vehin.AttValue("VOLUME") & vbCrLf & "==============================" & vbCrLf
        End If
    Next                                                                        'i
    For i = 0 To 1000
        SIM.RunSingleStep
        If vehicles.Count > 0 Then
            Call ShowAllVehicles
        End If
        vis.DoEvents
    Next
    SIM.Stop
    
    MsgBox "End() Success"

Sub showAllvehicles

    Dim j
    For j = 1 To vehicles.Count
        Set vehicle = vehicles(j)                                               'or vehicles.Item(i)


        msgbox "Vehicles.count=(" & vehicles.Count & ");j=" & j
        msgbox "vehicle.name=" & vehicle.Name
        msgbox "vehicle.ID=" & vehicle.ID
        msgbox "vehicle.AttValue(POINT).X=" & vehicle.AttValue("POINT").X
        msgbox "vehicle.AttValue(POINT).Y=" & vehicle.AttValue("POINT").Y
        msgbox "vehicle.AttValue(POINT).Z=" & vehicle.AttValue("POINT").Z


        Set vehicle = Nothing
    Next          
End Sub

大约就是这个样子.循环是相当的多的....

仅限于做少量的测试.
