00:00:00,000 --> 00:00:02,750
(dramatic music)

2
00:00:07,560 --> 00:00:09,690
- [Narrator] More than 95% of adults

3
00:00:09,690 --> 00:00:12,000
in the US own a cell phone.

4
00:00:12,000 --> 00:00:15,120
Of those, over 80% use a smartphone.

5
00:00:15,120 --> 00:00:18,270
With this portable
technology literally in hand,

6
00:00:18,270 --> 00:00:20,610
information about mobility patterns

7
00:00:20,610 --> 00:00:22,380
can be collected much faster

8
00:00:22,380 --> 00:00:23,823
than current methods.

9
00:00:24,690 --> 00:00:27,030
The Center for Transportation Research

10
00:00:27,030 --> 00:00:30,420
and the Texas Department of
Transportation investigated

11
00:00:30,420 --> 00:00:33,240
how to apply this data
to maintain good levels

12
00:00:33,240 --> 00:00:37,080
of service throughout the
state's transportation system.

13
00:00:37,080 --> 00:00:38,794
- This project is using devices

14
00:00:38,794 --> 00:00:42,180
that we all now have access
to, namely smartphones.

15
00:00:42,180 --> 00:00:44,730
It's collecting a large
amount of data passively

16
00:00:44,730 --> 00:00:46,299
almost without us being aware,

17
00:00:46,299 --> 00:00:50,670
and it's tracking general
origin, destination,

18
00:00:50,670 --> 00:00:52,710
travel patterns of individuals.

19
00:00:52,710 --> 00:00:54,570
And our traditional analysis tools

20
00:00:54,570 --> 00:00:56,430
for analyzing the movement of people

21
00:00:56,430 --> 00:00:58,170
in goods were developed largely

22
00:00:58,170 --> 00:01:00,210
prior to these new technologies.

23
00:01:00,210 --> 00:01:02,190
So this project was needed to explore

24
00:01:02,190 --> 00:01:04,470
how we could best
leverage the data provided

25
00:01:04,470 --> 00:01:05,970
by these new technologies

26
00:01:05,970 --> 00:01:07,680
in our work in transportation planning.

27
00:01:07,680 --> 00:01:10,395
- So this project was to
look at what's out there,

28
00:01:10,395 --> 00:01:12,690
kind of sift through everything

29
00:01:12,690 --> 00:01:15,330
and begin to categorize it and figure out,

30
00:01:15,330 --> 00:01:17,580
okay what's the current status of today?

31
00:01:17,580 --> 00:01:18,413
Can it be used?

32
00:01:18,413 --> 00:01:20,506
And how can it be fused
with the current processes

33
00:01:20,506 --> 00:01:23,400
and the current traditional data sources?

34
00:01:23,400 --> 00:01:24,870
- Well, this project will enable us

35
00:01:24,870 --> 00:01:25,950
to better understand

36
00:01:25,950 --> 00:01:28,881
where we need to incorporate this ICT data

37
00:01:28,881 --> 00:01:30,510
and where we can augment

38
00:01:30,510 --> 00:01:32,370
our traditional data collection efforts

39
00:01:32,370 --> 00:01:35,190
with these new passive data sources.

40
00:01:35,190 --> 00:01:36,720
It also provides a mechanism

41
00:01:36,720 --> 00:01:39,960
for us to select which data
sources are the most promising.

42
00:01:39,960 --> 00:01:41,730
And the fact is we need to consider

43
00:01:41,730 --> 00:01:43,140
when trying to incorporate them

44
00:01:43,140 --> 00:01:45,150
into our modeling processes.

45
00:01:45,150 --> 00:01:46,320
- It will cost time

46
00:01:46,320 --> 00:01:49,530
and money to process through
that big, big, big, big data.

47
00:01:49,530 --> 00:01:52,533
So our kind of main conclusion was,

48
00:01:53,550 --> 00:01:54,960
yes, it'll be important in the future,

49
00:01:54,960 --> 00:01:57,090
and yes, TxDOT needs to kind of be aware

50
00:01:57,090 --> 00:02:00,600
of it and have it at the back burner

51
00:02:00,600 --> 00:02:01,740
and start to introduce themselves,

52
00:02:01,740 --> 00:02:04,680
but it's not gonna replace
the current processes

53
00:02:04,680 --> 00:02:07,590
and collection methods
that are being used today.

54
00:02:07,590 --> 00:02:10,350
- Our ultimate goal is to
better understand person

55
00:02:10,350 --> 00:02:11,280
and vehicle movement

56
00:02:11,280 --> 00:02:13,800
so that we can calibrate
our travel demand models

57
00:02:13,800 --> 00:02:16,020
to reflect current travel patterns,

58
00:02:16,020 --> 00:02:18,450
which can then be used to forecast impacts

59
00:02:18,450 --> 00:02:21,600
to various demographic, technological

60
00:02:21,600 --> 00:02:23,880
and transportation investment scenarios,

61
00:02:23,880 --> 00:02:25,650
so that we can continue our goal

62
00:02:25,650 --> 00:02:28,740
in providing a safe and
efficient transportation system

63
00:02:28,740 --> 00:02:30,060
and connect you to Texas.
