- [Narrator] Information from
the Automated Traffic Signal

4
00:00:08,520 --> 00:00:11,700
Performance Metric system is
used to improve efficiency

5
00:00:11,700 --> 00:00:13,080
and safety for drivers.

6
00:00:13,080 --> 00:00:15,060
The Texas Department of Transportation

7
00:00:15,060 --> 00:00:17,340
along with researchers from
the University of Texas

8
00:00:17,340 --> 00:00:20,760
at Arlington work to develop
the ATSPM in the loop

9
00:00:20,760 --> 00:00:23,730
simulation framework filling
the gap between planning,

10
00:00:23,730 --> 00:00:26,370
design and implementation stages.

11
00:00:26,370 --> 00:00:30,930
- We realized that it's important
to incorporate the ATSPM

12
00:00:30,930 --> 00:00:34,650
concept into traffic
signal planning and design

13
00:00:34,650 --> 00:00:36,960
before we actually deploy it.

14
00:00:36,960 --> 00:00:41,040
Plus, we need a better
training program to help Texas

15
00:00:41,040 --> 00:00:45,120
operate the system and
gather most out of it

16
00:00:45,120 --> 00:00:46,890
and to tackle these challenges,

17
00:00:46,890 --> 00:00:51,780
we're using traffic simulation
as a stand in for ATSPM data.

18
00:00:51,780 --> 00:00:54,240
This way we can test the
traffic signal timings

19
00:00:54,240 --> 00:00:59,240
before deployment and show
how ATSPM system works.

20
00:00:59,460 --> 00:01:03,270
- We create a new solution
or software package

21
00:01:03,270 --> 00:01:07,230
to connect simulation
and traffic simulation

22
00:01:07,230 --> 00:01:10,650
and ATSPM system 'cause two system

23
00:01:10,650 --> 00:01:11,940
they belong to different worlds,

24
00:01:11,940 --> 00:01:14,850
they don't know each other
in the last 20 years.

25
00:01:14,850 --> 00:01:18,540
So using the simulation
of the output to feed

26
00:01:18,540 --> 00:01:22,440
the real world ATSPM system,
as a result the ATSPM system

27
00:01:22,440 --> 00:01:25,230
can generate all the performance measures

28
00:01:25,230 --> 00:01:28,620
the same as they are being
generated in the real world.

29
00:01:28,620 --> 00:01:31,710
- We got the green light
for phase two project

30
00:01:31,710 --> 00:01:35,130
to fine tune the software
and documentation

31
00:01:35,130 --> 00:01:37,020
and we plan to use these two

32
00:01:37,020 --> 00:01:39,510
in our current deployment projects.

33
00:01:39,510 --> 00:01:44,220
- This tool is really help
them to quickly pick up

34
00:01:44,220 --> 00:01:46,980
the experience or
provide a scientific tool

35
00:01:46,980 --> 00:01:49,470
even for the new traffic signal engineers

36
00:01:49,470 --> 00:01:52,680
when they design a system
with this complexity.

37
00:01:52,680 --> 00:01:57,060
So instead of using the
experience from a supervisor

38
00:01:57,060 --> 00:01:59,670
or mentor or have to develop by themself

39
00:01:59,670 --> 00:02:04,200
they can simulate users to
see what's going on there.

40
00:02:04,200 --> 00:02:06,330
- This project can really improve

41
00:02:06,330 --> 00:02:08,340
how we design traffic signals,

42
00:02:08,340 --> 00:02:11,550
especially the more complicated ones.

43
00:02:11,550 --> 00:02:15,057
It also boosts the training
program for ATSPM (indistinct).

44
00:02:16,320 --> 00:02:18,150
This systems basically
makes traffic signals

45
00:02:18,150 --> 00:02:20,580
that are more efficiently and safely

46
00:02:20,580 --> 00:02:23,610
which is great news for
everyone on the road.
