(logo whooshing)

00:00:08,730 --> 00:00:09,810
- [Narrator] Extreme weather events

3
00:00:09,810 --> 00:00:14,200
such as flooding,
tornadoes, and hurricanes

4
00:00:15,270 --> 00:00:17,193
are becoming more numerous in Texas.

5
00:00:18,390 --> 00:00:21,090
Assessing the impact to the
Texas Transportation Network

6
00:00:21,090 --> 00:00:24,000
is vital to lessening the
effects of such events

7
00:00:24,000 --> 00:00:25,500
when they occur.

8
00:00:25,500 --> 00:00:28,290
Working with the Texas A&M
Transportation Institute,

9
00:00:28,290 --> 00:00:30,030
the Texas Department of Transportation

10
00:00:30,030 --> 00:00:32,250
has developed a scorecard and other tools

11
00:00:32,250 --> 00:00:35,250
to effectively integrate
infrastructure resiliency

12
00:00:35,250 --> 00:00:37,380
into transportation planning.

13
00:00:37,380 --> 00:00:39,180
- Our primary goal in this project

14
00:00:39,180 --> 00:00:43,689
has been to help TxDOT

15
00:00:43,689 --> 00:00:47,430
to then other transportation organizations

16
00:00:47,430 --> 00:00:49,230
in the state like MPOs,

17
00:00:49,230 --> 00:00:51,900
to operationalize resiliency practices

18
00:00:51,900 --> 00:00:54,450
in planning and project development.

19
00:00:54,450 --> 00:00:57,510
- Texas is an extremely large state

20
00:00:57,510 --> 00:01:02,510
and experience different
environmental impacts

21
00:01:03,510 --> 00:01:07,440
depending on what location
you are in the state of Texas.

22
00:01:07,440 --> 00:01:10,500
So it was extremely important

23
00:01:10,500 --> 00:01:14,520
to not simply develop
a statewide strategy,

24
00:01:14,520 --> 00:01:19,520
but to develop a tool and a
mechanism that was customizable

25
00:01:21,330 --> 00:01:25,200
for addressing the specific
issues that occurred

26
00:01:25,200 --> 00:01:30,200
within the region being looked
at in the state of Texas.

27
00:01:30,840 --> 00:01:33,780
We were looking for
information to be developed

28
00:01:33,780 --> 00:01:37,200
to inform us about future
planning, investments,

29
00:01:37,200 --> 00:01:42,200
and hardening of the
transportation network.

30
00:01:42,300 --> 00:01:46,949
- Impacts of extreme events
such as hurricanes, flooding,

31
00:01:46,949 --> 00:01:49,650
wildfires on infrastructure,

32
00:01:49,650 --> 00:01:53,340
specifically transportation
infrastructure is increasing

33
00:01:53,340 --> 00:01:57,660
with the climate changes
and it causes disruption

34
00:01:57,660 --> 00:02:00,060
in these systems when these events happen,

35
00:02:00,060 --> 00:02:02,580
and these disruptions
can have catastrophic

36
00:02:02,580 --> 00:02:05,010
economic and social effects.

37
00:02:05,010 --> 00:02:08,490
We did a statewide
Transportation Network Analysis

38
00:02:08,490 --> 00:02:12,540
to rank the road networks
and the road segments

39
00:02:12,540 --> 00:02:13,800
in terms of their vulnerability

40
00:02:13,800 --> 00:02:16,320
of criticality based on
four different measures.

41
00:02:16,320 --> 00:02:18,810
Measures related to exposure to flooding,

42
00:02:18,810 --> 00:02:21,690
measure related to access
to critical facilities,

43
00:02:21,690 --> 00:02:24,600
measure related to physical proximity

44
00:02:24,600 --> 00:02:26,250
to other infrastructure.

45
00:02:26,250 --> 00:02:29,640
And of course the issues
related to connectivity

46
00:02:29,640 --> 00:02:32,460
of the entire road network
to facilitate evacuation

47
00:02:32,460 --> 00:02:33,633
and also response.

48
00:02:34,680 --> 00:02:38,100
By accounting for the measures
we created in this study

49
00:02:38,100 --> 00:02:41,370
and using the outputs of our analysis

50
00:02:41,370 --> 00:02:45,156
which is again implemented
at the state road network

51
00:02:45,156 --> 00:02:46,980
for the entire state.

52
00:02:46,980 --> 00:02:50,220
So every district of
TxDOT can know the level

53
00:02:50,220 --> 00:02:53,032
of criticality of every
single road segments

54
00:02:53,032 --> 00:02:54,480
based on different measures,

55
00:02:54,480 --> 00:02:56,010
so that then they can work to prioritize.

56
00:02:56,010 --> 00:02:58,140
For example, whether to allocate resources

57
00:02:58,140 --> 00:03:01,110
for rehabilitation of this road over here

58
00:03:01,110 --> 00:03:03,540
or this road over here, they
can prioritize and say, Hey

59
00:03:03,540 --> 00:03:05,430
this road has more
criticality, for example,

60
00:03:05,430 --> 00:03:08,130
in terms of exposure to flooding.

61
00:03:08,130 --> 00:03:10,740
Therefore, we need to retrofit

62
00:03:10,740 --> 00:03:14,460
and maintain this road and
prioritize it over this road.

63
00:03:14,460 --> 00:03:16,740
They can incorporate revitalization.

64
00:03:16,740 --> 00:03:19,680
- [Catherine] So behind
the scenes within TxDOT,

65
00:03:19,680 --> 00:03:24,270
the important thing is
that we work together

66
00:03:24,270 --> 00:03:27,630
with our stakeholders
and our other partners

67
00:03:27,630 --> 00:03:32,630
incorporating resiliency
as one of the many aspects

68
00:03:33,660 --> 00:03:37,350
of a project planning to ensure

69
00:03:37,350 --> 00:03:40,560
that the transportation
system remains intact

70
00:03:40,560 --> 00:03:42,540
so that the traveling public

71
00:03:42,540 --> 00:03:45,753
can get to where they
need to when they want to.
