LADOT’s announcement states that the Broadway report is the first one to use the department’s new “robust methodology for pre- and post-installation evaluation and data collection.” This evaluation process is outlined in a second report entitled Project Evaluation Manual V1.1 [PDF]. LADOT further states, “By using established metrics that illuminate how new public spaces and street design impact the life of the street, we can track trends over time, evaluate project performance, and inform future program direction.”
LADOT plans to do a corresponding post-installation study in Fall 2015 to compare the conditions before and after the Broadway Dress Rehearsal.
What does the report say about Broadway? Here are some highlights from LADOT’s announcement:
Pedestrians generally outnumber vehicles on Broadway. There were more people walking along Broadway over the course of just 6 hours than motor vehicles traveling along the corridor over a 24-hour period on the same weekend day.
From 2007 to 2012, 120 intersection and 94 mid-block injury collisions were reported along Broadway (involving people driving, walking, and bicycling).
Pedestrian and bicycle injury collisions have been increasing.
Most mid-block collisions were caused by unsafe lane changes and unsafe speed by drivers.
Vehicular speeds and volumes differ for northbound vs. southbound traffic. Traffic speeds were higher and volumes lower going southbound; traffic speeds were lower and volumes higher northbound.
Excessive driver speeding behavior was observed. Almost one-quarter of drivers were speeding while heading south on Broadway on the weekday studied.
The report is chock-full of great visuals, breaking down all sorts of data, even differentiating the east and west sides of Broadway. There is information on motorists yielding, motorist encroachment on crosswalks, bike and pedestrian counts, speeding, collisions, spending, tax revenue, and even pedestrian group size and posture (standing vs. sitting).
