<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal">The Telenav Map team has done some research on the status of the ways and relations of Trans-Canada Highway.
<o:p></o:p></p>
<p class="MsoNormal">Here are some conclusions from this research: <o:p></o:p></p>
<ul style="margin-top:0cm" type="disc">
<li class="MsoNormal" style="mso-list:l3 level1 lfo1">The highway is formed from 30 routes;<o:p></o:p></li><li class="MsoNormal" style="mso-list:l3 level1 lfo1">Every route has different names for the name tag, such as: street names, other routes names or Trans-Canada highway name in different forms;<o:p></o:p></li><li class="MsoNormal" style="mso-list:l3 level1 lfo1">The issue above is repeating for the ref tag;<o:p></o:p></li><li class="MsoNormal" style="mso-list:l3 level1 lfo1">The name of Trans-Canada highway has more than one form (Trans-Canada Highway, TransCanada Highway, Trans Canada Highway, etc);<o:p></o:p></li><li class="MsoNormal" style="mso-list:l3 level1 lfo1">Another issue is the variety of names in other tags related to it (such as: name:en, name:fr, alt_name, alt_name:en, alt_name:fr, nat_name);<o:p></o:p></li><li class="MsoNormal" style="mso-list:l3 level1 lfo1">There are some routes that don’t have a route name only ref (5 routes);<o:p></o:p></li><li class="MsoNormal" style="mso-list:l3 level1 lfo1">There are some routes that overlap:
<o:p></o:p>
<ul style="margin-top:0cm" type="circle">
<li class="MsoNormal" style="mso-list:l3 level2 lfo1">in Manitoba: - PTH 1 (MB Trans-Canada Highway) and Trans-Canada Highway (Super);<o:p></o:p></li></ul>
</li></ul>
<p class="MsoNormal"> - Yellowhead Highway and PTH 16 (MB Trans-Canada Highway);<o:p></o:p></p>
<ul style="margin-top:0cm" type="disc">
<ul style="margin-top:0cm" type="circle">
<li class="MsoNormal" style="mso-list:l3 level2 lfo1">in Alberta: Trans-Canada Highway (AB) and Trans-Canada Highway (Super);<o:p></o:p></li><li class="MsoNormal" style="mso-list:l3 level2 lfo1">in British Columbia: - Trans-Canada Highway (BC, Super) and Trans-Canada Highway;<o:p></o:p></li></ul>
</ul>
<ul style="margin-top:0cm" type="disc">
<li class="MsoNormal" style="mso-list:l0 level1 lfo2">About 90% of these routes are broken;<o:p></o:p></li><li class="MsoNormal" style="mso-list:l0 level1 lfo2">About 80% of these routes have highway value flip flop (motorway, trunk, primary);<o:p></o:p></li></ul>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal" style="text-indent:18.0pt">We propose to make some improvements to standardize all the routes. We would like to get your thoughts and feedback on the following questions:<o:p></o:p></p>
<ul style="margin-top:0cm" type="disc">
<li class="MsoNormal" style="mso-list:l1 level1 lfo3">What is the correct form for the name that appears in the way name tag? For example: “Highway 417” is part of Trans-Canada Highway and has the name value tag “Highway 417”. To resolve this issue, we would
need to standardize the ways’ name tag for all the provinces. The question is, should we modify the way names in to “Trans-Canada Highway”, or should we insert the name “Trans-Canada Highway” at the end of the name, like this: “Highway 417 (Trans-Canada Highway)”,
or should we leave it like it is? <o:p></o:p></li><li class="MsoNormal" style="mso-list:l1 level1 lfo3">Another issue is related to the official name of the highway. According to our research the official name for Trans-Canada Highway is “Trans-Canada Highway”. In our research we have found several forms of
this name: TransCanada Highway, Trans Canada Highway, etc. Should we change all the names to “Trans-Canada Highway”?<o:p></o:p></li></ul>
<ul style="margin-top:0cm" type="disc">
<li class="MsoNormal" style="mso-list:l2 level1 lfo4">Another question is related to the priority of the names in the name value tag and also for the ref tag. If we have a way that has a street name (“Old Highway 16” or “North York River Road”) and two routes
that overlap (ex: Trans-Canada Highway and Highway 11). What is the name and the ref that should appear in the way name tag and ref tag?
<o:p></o:p></li><li class="MsoNormal" style="mso-list:l2 level1 lfo4">In case of overlapping identical routes (ex: in Manitoba there is two routes for Trans-Canada Highway). What should be the best approach?<o:p></o:p></li><li class="MsoNormal" style="mso-list:l2 level1 lfo4">In case of highway value flip flop (motorway, trunk, primary), there are several segments like this outside the cities (ex.: Route “Ontario Highway 17 (Blind River to North Bay) (ID 3739829)”, or Route “Trans
Canada Highway 104” (ID 1732797)). For areas outside the cities we propose to change the highway value into motorway/trunk. What do you think about this issue?<o:p></o:p></li></ul>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">We think that one approach to resolve the first problem could be to add “Trans-Canada Highway” or “Highway 417 (Trans-Canada Highway)” to the way name for all the routes, and the ref number correspondent to each route that forms the Trans-Canada
Highway.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We look forward to hearing your feedback and hope to improve the situation together.<o:p></o:p></p>
