back and get that. >> we do not have a set of third street cars or a set of cars for the j-line, so they should all be outfitted. supervisor cohen: i see. i heard a rumor that we have v- tags, but they do not all work. i just want to confirm or deny -- >> absolutely, sometimes we have v-tags that do not work. i am not defending things that will not work, but you do have many systems like ours. cars are 15 years old. they all interact. the v-tag interaction is the interface between two systems.

i would be happy to give you a sense of the failure rate on v- tag, how we maintain them and those kinds of things, but it is not a rumor. occasionally, the v-tag does not work. then you have to make an adjustment that can delay service as well. part of what we have to do is make sure v-tags work, that they are reliable and they do what they are supposed to do. i do not have the exact numbers, but i would be happy to provide, you know, a sense of, number one, are they on every card? they should be. i will check. and number two, what is the failure rates?

supervisor cohen: if a car leaves the central station and is working and somewhere along the line during its route, it becomes effective, how was that communicated to central command? >> two ways, and it is getting better. he is not only how you monitor v-tag, but how you monitor the system. the radio system, if they are in contact, the operator is in contact with the control center. right now, with the interaction, we're able to manage the service on a real-time basis. what that means, there is a board on the eighth floor or we can see the position of all the trains in the system at any time.

that indicates to us if the system is not moving, if there is a problem we are able to immediately say to the control center, call the operator, see what is going on. such as a train standing or sitting. real-time service management, if you will, on v-tag or anything else i would describe as three legs of a stool. you have the command center, which is the ability, the service people who can see all the trains. we had staff in september, and especially during rush hour, and they are the ones understanding if you make an adjustment, the control center, which is in direct contact with the operators is limited in the technology. you can see where all the trains are.

they are at the key portals. is a shared responsibility. we're looking at technology to supplement how we do that. our management team should follow up. if we have an incident and we do not repeated, the next day we understand, and if it is necessary to go beyond that. so -- supervisor cohen: it looks like i have colleagues who would like to have a word or two. >> hi. i am it with sustainable streets. i do not know much about the v- tag -- supervisor cohen: i am sorry. you are with you?

>> sustainable streets. supervisor cohen: is that mta? >> with nt 8. i know how the v-tag interacts and i wanted to share information about that. supervisor cohen: thank you. >> i know about the detectors on the streets. it is in our sf go transportation management center. last year we were able to upgrade to these logs. until last september when a v- tag failed, we would only know if someone complained. as of last september, we were able to add the logs, and if

there is a failure, we send it over to the muni maintenance, and a repair a. -- and they prepare a. the failure is about 1%. failure does not mean it does not work. it means that particular transit detector -- it is not working, it does not mean the whole transit areas not working. is just slightly less efficient. supervisor cohen: can you briefly describe for the public the purpose of the v-tag? >> sure. there is a detector in the pavement and also on the vehicle. when the vehicle runs over the detector in the payment, there is a communication between the detector and the traffic signal that basically says, hi, i am a

train. i am at 30th and carroll. and the detectors in the traffic signal will estimate the time it will take to get their. if the detector at carroll is not working, we do not have the advanced 30 seconds noticed the train is coming. supervisor cohen: ok. since i have you here, can you talk to me about the prioritization of the third street corridor? house synchronized? >> sure. from 4th and king down to the bay shore has transit signal priority. we have a system several signals

a way. whenever ran the t-line without priorities -- we never ran the t-line without prior ries. our models show we are saving about 20% of our running time if we did not have the priority is in place. we think we would reduce our men time by about 25% by having priorities in place. supervisor cohen: would you say that having the t has decreased the time from visitation valley to the market by tenants? but i do not have the data. supervisor cohen: ok. so, you mentioned about broken v-tags. how do we go about replacing it? >> i guess i can only talk about

the intersection side. it is usually up parts -- a part of the filter that means to be replaced. if it is part of the filter, they replace it. if not, they do what ever they have to do. supervisor cohen: i of one last question. what is your strategy to limit the traffic flow on the third street corridor. >> bonnie t third corridor, the train is the highest priority. we try to reduce travel time for transit first, and then we look at traffic. usually you have a coordination

plan where each signal turns green for a certain time. you keep going. the next light turns green. we haven't set up to work for the cars, but when the train comes, -- we had it set up to work for the cars, but when the train comes, we do what we need to do within reason. we have to make sure that pedestrians can cross the street safely. we never shortened the what. we do switch around the times to allow the travel time for transit. supervisor cohen: that is the coordination plan for third street? >> yes. supervisor cohen: ok, thank you. ok.

i am not sure if you are the most appropriate person, but regarding the fourth and king street intersection, this intersection has great delays on the system. what is the primary problem there, and hasn't been addressed? >> fourth and keene is an extremely complicated intersection. -- fourth and keen is an extremely -- fourth and king is an extremely complicated intersection. there is the turning he banged -- the turn lane. one of them will have to wait a signal cycle, which means reduced travel time getting through that intersection. is a problem.

i agree. both of the trains are going on a through direction, and that will not happen anymore. supervisor cohen: thank you. i'd like to call mr. mason to the podium. folks, i am almost done. i just want to talk about the t- line, get clarification. so, tell us the overall strategy. >> the overall strategy for the t-line -- we have transit fare at inspectors. there was an audit conducted about a year ago, with the concern that the t-line, the fare increase was the highest on the t-line. the fare inspectors were moved

to muni metro, so they could have a more concentrated effort, and that is all the way up to a third straight. you have more of those folks up there. there are folks that are completely dedicated to that area. supervisor cohen: is this a standard approach to fare evasion? or is this unique to the se? >> i'm not going to say it is unique, because we have targeted this line. i do not want to say it is just 33. we have a concentrated effort on the line. it is a high target area where we see the need for fair enforcement.

supervisor cohen: ok. ok, folks. i am done with my questions. supervisor mar: i think we should open this up for public comment. supervisor cohen: i think we should. i would like to call up linda richardson. >> good afternoon, supervisors. thank you for putting this together. i just want to establish there are substantial improvements on the t-line. we attribute that to a substantial improvement in public safety. i think in the last year, supervisor mar mentioned with the killing in hunters point, i think muni has gone beyond the call of duty. i am here today, representing

the bayview/hunters point land use committee. supervisor cohen mentioned that we worked very tirelessly. i think the fundamental issues we found have still not been resolved. i think muni actually did not consider the t-line to be a dedicated line. hunters point spent months working with need to try to change that, and. -- with no need to try to change that. the fact that you are combining heavy usage, and you would have that, and again, it is not a

coincidence. sooner or later, we will have the problems that we are having right now. you are pulling in and you are pulling alps -- pullng out, and it seems to me at some point they do not have the right of way. one of the problems come up when you are at the subway and to try to track the moment -- the movement, we are sitting there, and you can track the end and everything else. it is somewhere. it is no where. the only thing about the t-line -- at that point some of people are nowhere to be found. that needs to be corrected. a think when you look at the growth in the southeast -- i think when you look at the growth in the southeast, the mission bay, this is the lifeblood.

this is going to be the largest sector with the population, and so, let's deal with that right now. have the t as a sedicated line. and you need to tell us what the start or end point is going to be. [chime] and it needs to work. it will cost performance later. supervisor mar: thank you. >> first and foremost, in this deliberation, i think the right question needs to be asked. you know, supervisors, you ask like commissioners or something for the san francisco transportation authority, right?

you have a commissioner from district 10 who should be here. do we have that person here? if you do not have that person here, you need to find out why. there used to be a person who represented us, and throughout that time, she has not been doing her work well. having said that, when we have the 15 and third, it was a perfect system. you could take the bus from city college of the way to chinatown. the third street, all this deliberation, they talk the talk, but they cannot walk the walk. there are many factors. non-and the main factors is we do not have the software.

we have all trains. the second factor is. if you take a certain portion of the lines, the third light rail perform somewhat well. the other day, i was waiting, and 3 trains -- not one, not the law -- not two. we waited 50 minutes for the train. supervisor mar: where was this? >> the bay shore. it is quite a popular hub. you wait for 15 minutes.

you have an algorithm. you can use the algorithm and reduced the statistics. this is the point. in the past, the fifteen and third performed well. today, the third street light rail should be given an f-minus. that is my analysis. what i heard today was an analysis of the paralysis. we do not need that. when it comes to the language, most of the chinese constituents take a different line to get to chinatown you bang -- to giant dump. many others who speak chinese. -- to chinatown.

they need others to speak chinese. [chime] >> good afternoon, supervisors. i am it long time in muni -- i am a longtime muni rider living in district 10. thank you for holding this meeting and for your sensitivity to the diverse riders in district 10. i want to suggest that in addition the finding of broadcasters on the buses, muni bad -- add 311.

this is easy to transition over. if the project is supposed to have riders, this department would have been assessing our diverse residence for all these years, and not just this year. muni would have recommended -- rather the tep would have recommended to muni to repair these, especially in the front. it is really problematic, especially in the morning and early afternoon. so riders are very vulnerable. how can anyone forget the video

of that helpless woman who was thrown off last year. tep should do periodic trilingual oral and written input from our diverse residents said they are really serving the residents of the southeast areas. > walter paulson. ♪ i'm sitting downtown hope the minu is on time sitting downtown waiting for the t-line why don't you fix it?

we have been waiting long, and i hope you fix it fast please some are even faster like you always see so i am saying to you i am sitting downtown hoping the muni t is on time sitting downtown, and i hope it comes around in it is going to be fast again on time ♪ supervisor cohen: ok, thank you. >> good afternoon, supervisors. my name is joe voss. i am probably hear more as a resident than anything else.

i very rarely use the t-line, because i cannot afford the extra 12-15 minutes it takes to get from my house to the city. pete improvements were supposed to be made -- the t-line might have originally gone across the third street light rail. in makes sense -- it makes sense. at this point, i am trying to be very supportive of muni's need for more rolling stock. do indymac. if you put the 15 back -- do

the math. if you put the 15 back, you might find there would be a great amount of savings. maybe, that would be the magic answer. i realize there are federal funds and all these other things that could be impediments. on the right-hand side, they put everything you can do, and on the left-hand side, you put everything you can do, and i just finished pulling the appeal of the permanent -- permit. the coach facility to replace

the kirkland yard. it will be a diesel facility. however, there are not a lot of hybrid diesels yet. i did go on and on. but need has to show up to the meeting where two people with any knowledge. we asked for the questions to be transcribed. could we see them. we have to answer. we will see if you wrote down what we think you are supposed to cover.

i just cannot say enough about my frustration with muni. maybe they need more employees. i do not know. >> good afternoon, supervisors. thank you for spreading the information on the e-mail's. we have an opportunity to communicate and share. i live on the most beautiful street in san francisco. in an engineer -- i am and engineer and there are a few prospective i have.

also, i have been part of the state's deep product to the department of public health. before coming here, i surveyed a few members blinis domino games. -- a few members playing these domino games. the communication issues were highlighted before by mr. deco sta and a few others. the design intent is not being met. supervisor cohen, i am glad you're asking some many good questions. we have senator feinstein and senator boxer and th
