I've attached the second release of the ColdFusion Yahoo Package. It now includes APIs for Traffic and Weather data. Here is a few examples.
Traffic
<cfset trafficAPI = createObject("component", "org.camden.yahoo.traffic")><cfinvoke component="#trafficAPI#" method="trafficSearch" returnVariable="result"> <cfinvokeargument name="zip" value="90210"> </cfinvoke>
<cfdump var="#result#" label="Zip search for 90210">
Weather
Weather is a tiny bit more complex. It has 2 public methods. One to get the current weather and one to get the forecast.
<cfset weatherAPI = createObject("component", "org.camden.yahoo.weather")><cfinvoke component="#weatherAPI#" method="getWeather" returnVariable="result"> <cfinvokeargument name="location" value="70508"> <cfinvokeargument name="units" value="F"> </cfinvoke>
<cfdump var="#result#" label="Weather for Lafayette, LA">
<cfinvoke component="#weatherAPI#" method="getForecast" returnVariable="result"> <cfinvokeargument name="location" value="70508"> <cfinvokeargument name="units" value="F"> </cfinvoke>
<cfdump var="#result#" label="Forecast for Lafayette, LA">
