1 00:00:00,000 --> 00:00:05,000 (dramatic music) (screen whooshing) 2 00:00:06,883 --> 00:00:08,910 (traffic whooshing) 3 00:00:08,910 --> 00:00:10,470 - [Narrator] How traffic signals operate 4 00:00:10,470 --> 00:00:11,670 is traditionally based 5 00:00:11,670 --> 00:00:14,490 on a set of uniform engineering standards 6 00:00:14,490 --> 00:00:16,440 but using real-world data gathered 7 00:00:16,440 --> 00:00:17,850 at local intersections, 8 00:00:17,850 --> 00:00:20,790 agencies can improve mobility and safety 9 00:00:20,790 --> 00:00:23,703 while tailoring operations to specific communities. 10 00:00:25,230 --> 00:00:27,600 The Texas Department of Transportation with help 11 00:00:27,600 --> 00:00:30,000 from the Texas A&M Transportation Institute 12 00:00:30,000 --> 00:00:31,170 has developed a set 13 00:00:31,170 --> 00:00:34,200 of guidelines for identifying data-driven strategies 14 00:00:34,200 --> 00:00:37,020 and techniques to improve traffic signal performance 15 00:00:37,020 --> 00:00:40,350 and operation more responsive to local needs. 16 00:00:40,350 --> 00:00:42,750 - Right now, a lot of our signals are run sort 17 00:00:42,750 --> 00:00:44,940 of in an isolated manner, 18 00:00:44,940 --> 00:00:46,740 which means that we don't get a lot 19 00:00:46,740 --> 00:00:49,740 of information back and a technician would have to go 20 00:00:49,740 --> 00:00:52,620 to the location to be able to troubleshoot. 21 00:00:52,620 --> 00:00:55,140 With advanced traffic signal performance measures, 22 00:00:55,140 --> 00:00:59,580 we get feedback from Signal for not only timing purposes 23 00:00:59,580 --> 00:01:03,000 but also for troubleshooting purposes for basic maintenance, 24 00:01:03,000 --> 00:01:04,350 things of that nature. 25 00:01:04,350 --> 00:01:06,120 - With the advances in technology, 26 00:01:06,120 --> 00:01:10,860 the newer controllers are able to log by 1/10 of a second 27 00:01:10,860 --> 00:01:13,470 everything that's happening at the intersection. 28 00:01:13,470 --> 00:01:15,690 Along with that, the advances 29 00:01:15,690 --> 00:01:18,900 in computation technology allows us tools 30 00:01:18,900 --> 00:01:22,830 to analyze these data so that we have a better idea 31 00:01:22,830 --> 00:01:25,710 of the performance of the intersection continuously 32 00:01:25,710 --> 00:01:26,820 so that we can go back 33 00:01:26,820 --> 00:01:29,130 and see how the intersection is performing 34 00:01:29,130 --> 00:01:31,620 even before we get a complaint about it, 35 00:01:31,620 --> 00:01:34,530 so that we can then proactively respond 36 00:01:34,530 --> 00:01:37,069 to any issues that are at the intersection. 37 00:01:37,069 --> 00:01:38,820 (traffic whooshing) 38 00:01:38,820 --> 00:01:42,210 So this project's objective was to evaluate 39 00:01:42,210 --> 00:01:45,750 and assess the various tools that are available 40 00:01:45,750 --> 00:01:49,590 to analyze the high-resolution data that are being logged 41 00:01:49,590 --> 00:01:54,060 by the controllers, and understand the needs of TxDOT 42 00:01:54,060 --> 00:01:58,110 as an agency, understand the needs of individual districts 43 00:01:58,110 --> 00:02:01,890 and develop a systems requirement that would be suitable 44 00:02:01,890 --> 00:02:04,230 for TxDOT for statewide deployment 45 00:02:04,230 --> 00:02:07,293 and develop draft specifications. 46 00:02:08,610 --> 00:02:10,770 - The research objective was trying 47 00:02:10,770 --> 00:02:13,140 to see what equipment is needed, see what sort 48 00:02:13,140 --> 00:02:16,380 of improvements can be made along the corridors. 49 00:02:16,380 --> 00:02:19,140 Larger goals are basically to see 50 00:02:19,140 --> 00:02:21,300 how we can adjust our infrastructure 51 00:02:21,300 --> 00:02:23,610 to meet these additional needs 52 00:02:23,610 --> 00:02:27,210 for the ATSPM and make sure 53 00:02:27,210 --> 00:02:31,590 that we can provide the best travel solution to the public. 54 00:02:31,590 --> 00:02:34,470 - The next step that that would help 55 00:02:34,470 --> 00:02:39,470 in this venture is to have some technology transfer sessions 56 00:02:39,600 --> 00:02:43,110 with the individual districts so that they are more familiar 57 00:02:43,110 --> 00:02:46,050 with the requirements of ATSPM systems. 58 00:02:46,050 --> 00:02:47,730 One of the ways this can also be achieved 59 00:02:47,730 --> 00:02:51,270 is by implementing some pilot deployments of ATSPM Systems. 60 00:02:51,270 --> 00:02:55,440 This will facilitate the transfer of technology 61 00:02:55,440 --> 00:02:59,220 to the individual districts so that they are familiar 62 00:02:59,220 --> 00:03:02,310 with the requirements as well as benefits 63 00:03:02,310 --> 00:03:07,310 of ATSPM systems, and the operation of ATSPM systems. 64 00:03:08,520 --> 00:03:09,720 -
