<p class=MsoNormal>Emil,<o:p></o:p></p>

<p class=MsoNormal><br>
Thanks for the reply.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><br>
I'm trying to figure out a way to store between 12 to 24 crime
"speeds" which will take into account when the crime occurred. That
way you can find a route to and from school based on when you will be walking.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>I saw in several parts of the routing that speed is
multiplied by distance. I was wondering if it'd be possible to take additional
route parameters in (the current time) and try to store crime weights.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>I'm not sure if it's possible to fit that amount of
information into the current field used for speed, or if I could make
modifications to the data files.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>If this sounds difficult. I could also make a utility to
change just the speeds in the road network and run 12-24 routed processes (not
a long term solution; given I want this to be easy to deploy and have modest
hardware requirements).<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>I realize that the algorithm calculates the <b><i>shortest </i></b>routes
ahead of time. This doesn't limit the ability to add in weighting and other
factors during routing, does it?<o:p></o:p></p>
