We have a rail network and a set of trains (A,B,C???) that should go from one point to anther (A train from a1 to a2, B train from b1 to b2 etc). The main problem here is that two trains cannot be on the same segment in the same time (even if the segment is long). Our idea is to find the path for train A. Then block all the segments that train A crosses in the time it crosses them before we try to solve the path for train B. The question is how to block the segments. Should we use barriers ??? they do not have time limit (as far as I know). Should we use Historic traffic or Live traffic? How do we translate the information about the route of train A into one of these ways before we solve train B. It is clear that we will need code but any hint will help. Thanks Mody ... View more

I could not find PythonWin on 10.1 installation DVD �?? is it there? In the help (http://resources.arcgis.com/en/help/main/10.1/0021/002100000021000000.htm) you have a link but I could not find it there too. In other topic in the help: http://resources.arcgis.com/en/help/main/10.1/0021/002100000022000000.htm the buttons of PythonWin is used. Where can I get it from and should I do this? Thanks ...

Hi All We are trying to run system tools that are really a python scripts from Desktop 10.1 and get an error about wrong paramaters. We are trying two methods: IGeoProcessor pgp = new GeoProcessor(); IVariantArray parameter = new VarArrayClass(); parameter.Add(@"c:\temp\ForRT.gdb\people"); parameter.Add(@"c:\temp\ForRT.gdb\people_point_line"); pgp.Execute("PointsToLine_management", parameter , null); or: Geoprocessor GP = new Geoprocessor(); PointsToLine pointsToLine = new PointsToLine(); pointsToLine.Input_Features = @"C:\temp\ForRT.gdb\people"; pointsToLine.Output_Feature_Class = @"C:\temp\ForRT.gdb\people_PointsToLine"; GP.Execute( pointsToLine, null); Both ways gives the same error. Can anybody help? Thanks Mody ... View more

Hi all I need some ideas on how to perform some analysis. Here is the problem. We have some GPS points of moving cars. The GPS is not accurate and the delta from the real location can be 50 meters or more. We create lines from the points. We might snap it to roads network but in some cases in city the points can snap to the wrong street. What we are looking for is places where the person drove only once (or only twice). Because the route is not accurate we must translate the lines into raster in some kind of Kernel Density process and then check the raster. The problem is that if we have two lines the raster value is higher than if we have one line but when we move away from the two lines value we get similar values to the one line values. Can anybody think about a nice way to do it? Thanks Mody ... View more
