Ideally there would be 3 stations that buses/ trains travel to quickly, you should be able to get to a station on a bus in under 20 mins . Traveling from one station to the next should take 5-10mins tops. A bus from one station to the next should leave every 5 mins.
Some areas might benefit from a hub, which would be an area where a few buses come and connect the close neighborhoods. From a hub to a station should be quick and direct. I put some hub examples on the map in blue A, B, C, D. The hubs would allow for some smaller buses to run into communities that are not served as well.
An example of this system, if you were in Arlington or South Side Slopes, and want to get to Highland Park, the current bus estimate is an hour or more. With the station and hub method, you can catch a bus to the station in Hazelwood Green within 20 mins. From there you would take a 5 min ride to the East Liberty Station. From East Liberty Station it be about 10 mins to Highland Park. This systems cuts at least 20 mins off the travel.
The map above is not perfect but it gives an example of how we can simplify the bus system, and increase ridership. Putting a station in Hazelwood Green would help bring in businesses to the soon to be developed area.
Please let me know you thoughts.
