How do I define ID for a link? What's a link? Is it edge to edge or lane to lane? Is it connections as in network file? How is link defined?

Hi,

singlelink link: here you define the ID of the link for which you have a measurement.

value: here you define the number of the vehicles you measured for this link.

stddev is the standard deviation of this measurement. If you set a high stddev, it means that the traffic measurement on the respective link varies a lot.

Kind regards,

Hello,

I am trying to use cadyts to calibrate the flows in my network using loop count data.In sumo tutorial, the real flow file is  given as below

 

<measurements> <singlelink link="1to21" start="25200" end="32400" value="750" stddev="8" type="COUNT_VEH"/> <singlelink link="1to22" start="25200" end="32400" value="250" stddev="8" type="COUNT_VEH"/> </measurements> 

 

I am not getting what are the attributes of singlelink link, value, stddev denoting. Could anybody help me understanding given attributes of realflow file?
