From the midterm’s conclusion, there is a relationship between transit stations and non-vehicle families, but these evidences are not strong enough.
Midterm Review
![Page 4: Can Public Transit Affect Private Vehicle Use?](https://reader035.fdocuments.us/reader035/viewer/2022062410/56815f01550346895dcdbe9e/html5/thumbnails/4.jpg)
Add some new variables data like: low-income, travel behavior, distance from station.
Use more space analysis methods.
Try to find a stronger relationship between mass transit and private vehicle use and make some proposals to the current lines.
Final Objectives

The places which use public transit are concentrating along the bus and rail line.

The most walking influencing area of transit stations is limited around 1500 meters.

Create the final transit need index through four variables: density of non-vehicle families, %low-income families, %public transit use, distance from transit stations.

We can see the high transit need mostly distributing around transit station within 1 miles.

Analyses of Proposed Infill-Stations
From the right figure, there are some uneven distribution of stations in some part of bus line and rail line within high transit need area.
Because it is very hard to change railway’s station, so the proposed infill-stations are focus on bus stations in this report.

Analyses of Proposed Infill-Stations
We can see the road densities which around new stations are mostly the same as that around originally stations.
It is necessary to add some new stations in the original bus route, so the line can service more people.

Conclusion
The high transit need mostly distributing around transit station within short distance.
It is necessary to add some new stations in the original rapid bus 757 route, so the bus line can service more poor people and non-vehicle families, and encourage more people to use public transit rather than private vehicles.
