00:00:00,000 --> 00:00:02,583
(upbeat music)

2
00:00:09,510 --> 00:00:11,310
- [Reporter] With an estimated 600 deaths

3
00:00:11,310 --> 00:00:14,400
and 14,000 injuries of bicyclists in Texas

4
00:00:14,400 --> 00:00:15,840
over the last decade,

5
00:00:15,840 --> 00:00:18,720
researchers with the Texas A
and M Transportation Institute

6
00:00:18,720 --> 00:00:22,320
developed database strategies
for bicycle crash reductions.

7
00:00:22,320 --> 00:00:26,160
- So nationally there
was a lack of information

8
00:00:26,160 --> 00:00:30,840
on how effective bicycle lanes were

9
00:00:30,840 --> 00:00:33,360
in reducing the numbers of crashes.

10
00:00:33,360 --> 00:00:37,440
The study itself developed
crash modification factors

11
00:00:37,440 --> 00:00:42,360
that estimate the amount
of reduction in crashes

12
00:00:42,360 --> 00:00:47,280
that can be expected from
implementing bike lanes.

13
00:00:47,280 --> 00:00:49,170
- There is a need for research

14
00:00:49,170 --> 00:00:54,170
to see whether this facilities
improve the bicyclist safety,

15
00:00:54,360 --> 00:00:56,250
and when we're talking about designs,

16
00:00:56,250 --> 00:00:58,470
we mean like bicycle lanes,

17
00:00:58,470 --> 00:01:00,810
separated by lanes and et cetera

18
00:01:00,810 --> 00:01:03,360
that are designed for the bicyclist

19
00:01:03,360 --> 00:01:05,820
to share the road with the vehicles.

20
00:01:05,820 --> 00:01:09,450
In our research, we were mainly
focusing on the facilities

21
00:01:09,450 --> 00:01:13,020
that are installed on the
roadway where the bicyclist

22
00:01:13,020 --> 00:01:15,240
is sharing the road with vehicle,

23
00:01:15,240 --> 00:01:19,050
because that's where most
of the safety concerns are.

24
00:01:19,050 --> 00:01:23,417
One of the limitations
in this type of research

25
00:01:23,417 --> 00:01:26,640
is the limited availability of data

26
00:01:26,640 --> 00:01:28,890
which makes it difficult for us

27
00:01:28,890 --> 00:01:30,900
to conduct data driven analysis

28
00:01:30,900 --> 00:01:35,900
and see the impacts of this
facilities on bicyclist crashes.

29
00:01:36,150 --> 00:01:39,450
Our significant result was
that indeed bicyclist lanes

30
00:01:39,450 --> 00:01:42,990
they actually significantly
reduced the bicyclist crashes

31
00:01:42,990 --> 00:01:47,990
from between like 44 to 65%
depending on the facility type.

32
00:01:48,960 --> 00:01:51,840
I mean we could see that
the separated by lane

33
00:01:51,840 --> 00:01:55,710
or buffered by lane that
leave some sort of an offset

34
00:01:55,710 --> 00:01:58,740
between bicyclist and vehicles

35
00:01:58,740 --> 00:02:01,350
or like some sort of
a vertical separation.

36
00:02:01,350 --> 00:02:04,800
They have a lot more positive
impacts on bicycle safety.

37
00:02:04,800 --> 00:02:09,600
We could see over, I mean
almost like six to 5% reduction.

38
00:02:09,600 --> 00:02:13,170
- By having these crash
modification factors,

39
00:02:13,170 --> 00:02:18,170
entities such as TxDOT can better quantify

40
00:02:18,180 --> 00:02:23,180
or better justify making
investments in bicycle facilities

41
00:02:23,190 --> 00:02:25,440
and the results are consistent

42
00:02:25,440 --> 00:02:29,220
with the recent updates
to TxDOT's guidance

43
00:02:29,220 --> 00:02:32,010
on providing bicycle accommodations.

44
00:02:32,010 --> 00:02:35,580
So it just goes to further support

45
00:02:35,580 --> 00:02:37,380
the work that we are doing.
