Large urban areas are often interested in cutting down the amount of traffic on their streets, and it does not necessarily need to be a struggle. Some of them have found it is optimal to expand their network of trains and light rail transit into the suburbs. This type of expansion offers commuters an opportunity to get close to the city without sitting in traffic for hours. They can park their personal vehicle, board the train, and then can relax until they reach their city destination.
There will always be those visiting the city occasionally with a preference to drive their own vehicle, but others may see expanded service into the city as a way to avoid the hassle of traffic and parking. They might be more willing if the expansion is advertised in a manner that makes it affordable and convenient. Good scheduling could also be a bonus for those seeking other options.
Part of what draws people to use mass transit systems is the ability to move where they want easily through an urban area. Parking, traffic, the confusion of trying to navigate successfully to find a particular address are all issues many people prefer to avoid. Being able to let someone else do the driving while they concentrate on their destination can be a good way to attract more users. Those who visit the city on occasion could find it convenient, and regular commuters may discover an expanded system gives them the options they need to make it a good solution.
Daily commuting is often about being stuck in traffic, and many people would prefer to spend that time doing something they enjoy. For systems being built now, starting off by advertising that aspect of the expanded service could be a winner for those who recreated the system and those who might find it more pleasant to use over time.
