Its not as precise as that when we looked at the case studies but it was in that ballpark so it was interesting to see experience supporting that formula. And to supervisor camposs question to look at state legislation so our office is working with the mta but also our City Attorneys Office and beginning with the state and i wanted to highlight the case study for Portland Oregon for automated cameras looks like they use vans that drive into your neighborhood up to 4 hours takes pictures every 2 seconds triggered when somebody is going really fast but looks like an interesting use of new technology in school and work zones so its not throughout the city and its not there all the time but it could really be targeted strategically to help people be more aware of the speed limits in a targeted way could you just talk about automated enforcement cameras and just whether you you think thats a realistic change that we could make at the state possibly local level. Right. I think certainly base
Maclaren park and long street probably like sunset boulevard and a few others within the west side of the sunset but i think for a citywide approach and i know our mta is looking at calming traffic hopefully limiting speed limits is a part of that strategy and one other bit of information that you gave besides the london uk study showing that over the the 20year period reducing traffic collisions by forty percent in their efforts i think thats an important piece of data and i think you said that study found that by reducing speed limits by one Miles Per Hour reduces the number of collisions by 5 percent. That is correct chair mar it was a separate study but it found looking at a number of citys experienced a reduction of 1 mile per hour in average speed resulted in a reduction. Its not as precise as that when we looked at the case studies but it was in that ballpark so it was interesting to see experience supporting that formula.

Triggered when somebody is going really fast but looks like an interesting use of new technology in school and work zones so its not throughout the city and its not there all the time but it could really be targeted strategically to help people be more aware of the speed limits in a targeted way could you just talk about automated enforcement cameras and just whether you you think thats a realistic change that we could make at the state possibly local level. Right. I think certainly based on the port land experience and you point out the vans thats a good point its very mobile can go to where the problem spot is as can an officer on a motorcycle for example, but its a much more efficient approach for the same level of staffing the camera can be taking pictures of every speeding vehicle as compared to an officer say pulling over someone and issuing a citation and five cars are speeding by that the camera attached to the van would pickup photographs of all of those vehicles so theres a b

Limit prior to shows zones being put in place. Supervisor supervisor campos most of of the residential were 25 and dropped to 20 and then some some of the commercial and main streets were 30. Thank you. I just wanted to thank both of you for the great report i wanted to highlight that the speed limit compliance map that you gave is all over the city and i know the mta has identified the pedestrian high injury corridors and the map of the collisions due to speeding in the city tend to be concentrated south of market and supervisor christensen district but still theres a lot of injures on the west side where theres a lot of red lines in the speed limit compliance in streets that you can drive much longer distances like im just looking at this through Golden Gate Park i see a lot of red lines and maclaren park and long street probably like sunset boulevard and a few others within the west side of the sunset but i think for a citywide approach and i know our mta is looking at calming traff
