Hi Rama,
When you create a rule based trait you create it from a rule or signal, like "color"="blue" or "country"="US".
In order to pass these signals to AAM one method is to add a pixel with this data on the site, and making event calls. It can be a blank image tag of 1*1 pixel or can be a JS code, anything will work. Following are examples to embed that on a page to collect real time data in AAM:
<script src="https://<yoursubdomain>.demdex.net/event?c_events=test-hyphen&c_prop67=make%3Aabarth&prop67=make%3Aabarth"></script>
<img src="https://<yoursubdomain>.demdex.net/event?c_events=test-hyphen&c_prop67=make%3Aabarth&prop67=make%3Aabarth" height="42" width="42">
When applied like this on a web page, it sends data to AAM :

Thanks,
