L.A. is notorious for having no public transportation. While this is not technically true, it is a fact that the system is lacking and that most people get around by car. The chance that your coworkers have a metro card or use the bus is slim.
By Car: If you are buying a car, a GPS system will be worth the expense. Look into TomTom or Garmin if your car does not come with GPS, or at least a mount for your preferred smartphone GPS system. Parking in L.A. is not as difficult as in Boston or Manhattan, but apartments that come with a parking space are still valuable. If buying a car is not an option for you, you will want to live in the same neighborhood as your work. Try getting a Zipcar account for weekend excursions.
Taxi: Taxis are available in most busy parts of L.A. but not in all, so it is important to have a reliable cab number in your phone or an Uber account. Yelp rates Metro Cab as the best in L.A.
Public Transportation: Most public transport in L.A. is by bus with metro service in some areas. The public buses can carry bicycles on their front fenders. For the bus systems in Westwood, Santa Monica, and West Hollywood see: Bigbluebus.com and weho.org.
Downtown has a subway system as well as bus routes, neither of which should be ridden alone at night. More information can be found at metro.net and ladottransit.com. The San Fernando Valley also has its own bus and train system.
Traffic: What you’ve heard about L.A. traffic is not an exaggeration. To cross the distances between L.A. neighborhoods, even the ones that are closer together like Westwood and Santa Monica, will take at least an hour at rush hour by bus.
Flights: For travel by plane, LAX is the major international airport serving the region. LAX is often the best and cheapest place in the US for flights to Asia and Latin America. For domestic flights and cheaper fares, you can opt for the Bob Hope Airport in Burbank or the Long Beach Airport.
