We recently spent five weeks in Tel Aviv and relied exclusively on public transport. All the bus (and train) signs were in English and it was extremely easy to navigate the somewhat complex system. We even went through the "big change" and received one of the booklets explaining all the new routes in Hebrew. However we did make extensive use of the website which had an english option and I spent a couple of hours using the site and the book planning out our daily trips. Yes it was frustrating at times but it certainly helped. Coming from Miami where public transportation is a joke we found the system to be the best way to get around and had a lot of fun riding the buses but I can see how a tourist who is only in Israel for a short time and does not have luxury of the use of a computer or the time to do research would be frustrated. We also found the people and bus drivers most helpful and I would certainly go back to using the bus system on our next trip Israel. (Except for Kav 1 in Jerusalem which meanders through all the Haredi neighborhoods and takes forever to get anywhere) Plus as senior citizens it was a cheap way to get around with no parking or driving hassles.
