Transit Effectiveness Project

I went to a meeting tonight where there was a presentation on the transit effectiveness project in San Francisco. I wish I would have had my thumb drive as there were some fascinating maps with great data. I found them but they aren't high quality. Here is the link to the Geary data showing where people get on and off the bus. If only all transit agencies went and got this type of information, we would know a lot more about operations. The following maps are located in this presentation. All the screen shots below are courtesy of Muni.

Operating Speed: This shows where Muni is really slowed down by traffic. No Surprise that Van Ness and Stockton are some of the worst. I wish we would have had this data before the 3rd Street LRT project was started. Take a look at that street. Green. This is why data is important. It makes political decisions much easier. Now thats not to say that it won't get more congested as the are grows around light rail and it needed to become rail at some point, but there are many pressing needs in the city, mainly Van Ness and the long orange Geary.

Operating Speed

Boardings: This shows where people board the buses. The most effective transit is on the main corridors and major traffic generators. It's interesting to note that where there is a high capacity spine, there are a lot of boardings. Most noticeable is along Mission BART. It shows how system boardings would probably improve if BART was expanded to Geary then down 19th such as proposed by SF Cityscape. It would improve boardings on the bus lines connecting to the stations.


Trips: The above observation is proven below in that there is a missing link between the Sunset and Richmond districts. The red dots are total trips between districts. Since there are a lot of trips North from the Richmond South towards SF State it would make a lot of sense to have rapid transit fed by east west buses.

Travel Patterns

Data. It's an amazing thing. According to one AC Transit board member at tonight's TALC meeting, they will be doing this soon as well which should bring some even more interesting results.
