<body class='hmmessage'><div dir='ltr'>I personally see no problem with adding 'nodes' where the stop lines are so that another mapper in the future can add, say, 'highway:traffic_signals=stop_line' or something similar once we nail down how to 'link' all traffic lights in an intersection and come up with a proper tagging scheme that all routers accept. I know I always add that 'redundant' node when I'm doing a full scale cleaning of a highway so that there is less 'versions' in the history for said way. That's why I also almost always add nodes to business driveways along major highways in case another mapper wants to come along later and add the buildings/service ways that connect to the main highway. Saves them time too.<br><br>-James<br><br><div><hr id="stopSpelling">From: tod@fitchdesign.com<br>Date: Mon, 27 Jul 2015 22:13:53 -0700<br>To: yourvillagemaps@yahoo.com<br>CC: talk-us@openstreetmap.org<br>Subject: Re: [Talk-us] Am I mapping this wrong, or should the router be fixed for this?<br><br><br><div><blockquote><div>On Jul 27, 2015, at 6:41 PM, David Wisbey <<a href="mailto:yourvillagemaps@yahoo.com">yourvillagemaps@yahoo.com</a>> wrote:</div><br class="ecxApple-interchange-newline"><div><div><div style="background-color:rgb(255, 255, 255);font-family:HelveticaNeue-Light, 'Helvetica Neue Light', 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;font-size:16px;"><div id="ecxyui_3_16_0_1_1438046528941_4251"><span></span></div><div id="ecxyui_3_16_0_1_1438046528941_4236"><div id="ecxyui_3_16_0_1_1438046528941_4974"> This issue reminds me of something I saw a lot of recently on OSM</div><div id="ecxyui_3_16_0_1_1438046528941_4657" dir="ltr">in Fort Collins, Colorado.
