You should abandon the use of document.write When that's used _after_ the webpage has been rendered, it generally destroys the webpage. Getting directions takes time from the remote service, so not only do you need to use the results only after they have become available (i.e. in the callback) - you don't want to be doing document.writes at that time either.
Using setTimeout to wait for the return of asynchronous data is a dumb idea, you have no idea how long it might take. Use the callback facility - as soon as the data has arrived, the callback function that you defined runs. Simple and efficient. Which leads to the next obvious improvement, if you have more than one request and want to queue them one at a time, the place to handle the queuing is in that callback function too. "Here's the response, lets process that .... then set up the next request". -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
