The junction width also depends on the junction-radius parameter of the respective node (default 1.5). It may be more profitable to compute the desired values direction from the junction shape polygon (found in the .net.xml file).
Regarding the minimum length of 0.1m, this could be reduced by changing the value of POSITION_EPS in config.h (or windows_config.h) but should not be set to 0 to avoid undefined behavior. regards, Jakob 2016-06-10 21:20 GMT+02:00 Yifeng Zeng <[email protected]>: > Hello Jakob, > > I was trying to calculate the junction width (as blue lines shown in the > picture), as well as a distance from center-line of each lane to the left > side of the junction edge (as red lines shown in the picture). > > > Another irrelevant question, I understand that we have a 0.1 meter gap > between the lanes, is there a way that I can remove this gap or specify it > to be 0 ? > > > Thanks, > Yifeng > > > ------------------------------ > From: [email protected] > Date: Thu, 9 Jun 2016 07:55:12 +0200 > Subject: Re: [sumo-devel] Find edge boundary points > To: [email protected] > CC: [email protected] > > > Hello, > currently you can get neither of the points A-F from netedit (besides by > right-clicking on he canvas and chosing 'copy cursor position to the > clipboard'). > The .net.xml only contains the shape of the center-line of each lane.
