I have create BT filter by Web Request - Parameter Value, and I create threshold on Purepath Response Time as shown below
But I confused with that threshold, why not match with fact. I try create a traffic light, but when the value of average response time 336 ms, the traffic light show severe icon as shown below. It should just show the warning icon, same as the threshold.
Whats wrong with my threshold ?

As Enrico is saying, a traffic light chart will only indicate the threshold breach status for the entire timeframe that your looking at. So if your chart has a timeframe of 1 hour, if your measure hit the severe threshold at any point during that hour, your chart will show red X, regardless of what the current value for your measure is. You can view this much easier if you put in parallel a line chart, showing the threshold area so you can compare.
The only other option is to create an incident based on this measure. The incident chart shows 2 perspectives: the big area at the top represents the current value of the threshold breach, but you also get an area underneath it representing the value for the entire timeframe (like what the traffic light chart is doing):

That's very likely because your severe threshold has been violated somewhere within the dashboard's timeframe (30 minutes according to your screenshot). You have to understand that by default all chart types (inlcuding traffic light) will be looking at the timeframe selected either in the dashboard or the dashlet (if it overrides the dashboard one).
