Top Public Transportation Tips
A (hu)man with a PlanIf you're not sure you can do the public transportation thing, start small with one a goal of taking public transportation at least one day a week until you figure out the system. Before you know it, you'll be making friends and riding along with everyone else.
Come Fly With MeTry to reduce the number of plane trips you take and try not to use a plane for any trips under 1000km. Plane trips are way more environmentally destructive than automobile trips.
Get On the Bus
Write to your city representatives to request that your community upgrade their diesel buses to fleets of electric or biodiesel buses. This will reduce the CO2 emissions generated, reduce dependence on imported oil dependency1, and in the case of biodiesel engines actually run cleaner and more efficient than petrochemical diesel.2 Even diesel buses are worth getting on.
Try the bus or train for longer tripsBuses, trains, light rail and ferries generally have dedicated travel paths that are quicker than sitting alone in your car, which can cut down travel times. If you need to use a car, see if you can car-pool. Each of these options is much better than flying. In a car, four people would only be collectively responsible for emitting only 104 kilograms of CO2, whereas in a plane they would generate some 736 kilograms of carbon dioxide. A cross-country train trip would generate about half the greenhouse-gas emissions of driving a car.
Walk to schoolMost children live close enough to walk school, but few do. Instead of driving your children the few blocks, walk with them or allow them to take the school bus. Take it step further by helping organize a walking bus for other kids in your neighborhood.
Catch a taxiReally these are a form of public transport because you don't own them, and when you don't need the service they are made available for others to use. Look out for hybrid or pedi-cab taxis, or book with Zipcar or Uber for an even greener option.
Telecommute
Don't drive to the office, or fly to that conference, if you can arrange to complete your work/presentation electronically, or via video conferencing. Video conferencing uses at most just 7 percent of the energy used for an in-person meeting. In this age of the internet, there are so many tools that make telecommuting an effective and efficient way of working.
Buy fare saver ticketsReturn, weekly/monthly, or off-peak bus/train tickets are often significantly cheaper than single ride tickets, which will encourage you to use said bus/train more often.
Plan your tripObtain timetable and route-maps for your journey to know what to expect in advance. Many municipal public transport systems now have free online databases than will take your staring point and destination and calculate the fastest times and best route for your trip, not to mention the wonder that is google maps. This can take the uncertainty out of public transport travel.
Be a Change AgentIf you don't use public transport in your local area because the service doesn't work for you, for whatever reason, then get it changed. Write letters to your city newspaper, comment on their online stories that address urban travel, join a public transport advocacy group, and meet with your local government representative. Things won't change, until you inform people you want them to.
