I carry a Public Transit Map as part of my Commuter Kit and consider it essential.<br><br>With this I can determine complete alternate routes in the event that my normal commute route is disrupted by bridge failure etc. With this tool, I can also figure out best routes to avoid urban events (riots, demonstrations etc).<br><br>Urban survival is not necessarily calling on the same skills and tools that wilderness survival may use, and indeed "survial" may not even be the best term to describe the need. A commuter kit should be designed to help you deal with the typical and potential atypical events that may arise in your community.<br><br>Where commuter prepardness really is the same as wilderness prepardness in that you need to figure out what your are preparing for. By evaluating the difficulties you may face daily and figuring out a plan on how you will respond and then build a kit that helps you respond.<br><br>My commuter kit centers around dealing with natural or unnatural disasters that disrupt normal urban transit, communication and services. I overlap to wilderness skills in shelter, water, medical, and fire. I reality, it turns out that I just use my wilderness PSK and suppliment my daily carry bag with the urban tools, like the transit map, money, credit and ATM cards, flashlites and batteries, HAM radio etc.
