retail
stores),
job
creation,
and
enhancement
of
nearby
property
values.

–
improved
air
quality
and
energy
conservation.
Social
Benefits
-‐
quality-‐of-‐life
benefits
from
living
in

open
space
and
greenways
and
that
provide

opportunities
for
walking
or
cycling.
Health
and
Fitness
Benefits–
it
is
well
recognized
that
Americans
would
benefit
in
many
ways
from
a
more
active
lifestyle.
Bike
lanes,
sidewalks
and

17. History
1975
City of San Antonio’s Bicycle Master Plan
1975 San Antonio only had three bicycle
corridors, which consisted of McAllister
Park, a route connecting St. Mary's
University, Trinity University, San Antonio
College and Brackenridge Park, and a bike
trail along the San Antonio River in the
historic mission area.

31. What is Bicycle Suitability and Bicycle Level of Service (BLOS)?
Bicycle level of service (BLOS) attempts to place a rating on the
experience of bicycling on the transportation networks of collector,
arterial, service and local roads. The rating ranges from A to F, good to
bad respectively along the lines of the automobile level of service (LOS)
model.
a1ln(Vol15/L) + a2SPt(1+10.38HV)2 + a3(1/PC5)2
- a4(We)2 + C
where:
Vol15 = directional traffic (15 minutes time period)
L = total number of through lanes
SPt = effective speed limit (see below)
SPt = 1.12ln(SPP -20) + 0.81
SPP = Posted speed limit
HV = percentage of heavy vehicles
PC5 = FHWA’s five point surface condition rating
We = Average effective width of outside through lane

35. Why Aerial Photography or Orthophoto Imagery?
Orthophoto Imagery
Digital orthophoto is a computer-generated image of an aerial
photograph or aerial digitial image in which displacements caused by
camera orientation and terrain have been corrected and the image has
been projected to a standardized map projection.
In other words, digital orthophotos are special photos because they
have been processed to be spatially accurate.
The MPO has access to imagery at 4 inch pixel resolution
The resolution number represents the distance covered by one pixel in
the image. Therefore, a 4 inch image is an image where 1 pixel is equal
to 4 inches.
36. Aerial Photography
Our imagery is updated every year from our partnership with City of San Antonio,
Bexar County Appraisal District and Bexar Metro 9-1-1. Which are part of the
Strategic Geospatial Coordination Committee or SGCC

40. Pavement Condition
RATING PAVEMENT CONDITION
5.0 (Very Good) Only new or nearly new pavements are likely to be smooth enough and free of cracks
and patches to qualify for this category.
4.0 (Good) Pavement, although not as smooth as described above, gives a first class ride and
exhibits signs of surface deterioration.
3.0 (Fair) Riding qualities are noticeably inferior to those above; may be barely tolerable for high-
speed traffic. Defects may include rutting, map cracking, and extensive patching.
2.0 (Poor) Pavements have deteriorated to such an extent that they affect the speed of free-flow
traffic. Flexible pavement has distress over 50 percent or more of the surface. Rigid
pavement distress includes joint spalling, patching, etc.
1.0 (Very Poor) Pavements that are in an extremely deteriorated condition. Distress occurs over 75
percent or more of the surface.

72. Purpose of the 2010 Safety Study
§ Exceptional growth over the next 20 years, expecting 600,000 new
residents.
§ Introducing CRIS and safety data to our region.
§ Budget constraints limit the ability for the needed transportation
improvements making safety even more of a pressing issue.
§ Efforts to reduce the frequency and severity of crashes has long
been underway, this study offers a more coordinated effort across
local jurisdictions.

v Road Rage/Aggressive v The first automobile crash involving a cyclist in the United States occurred
Driving in New York City in 1896, when a motor vehicle collided with a bicyclist.
(www.cycling.org)
v Cyclists were the highest paid athletes in the U.S. until Babe Ruth joined
v Cell Phone Use the Yankees.(www.cycling.org)
v Helmet use has been estimated to reduce head injury risk by 85 percent.
v Twenty-onestates and the District of Columbia have helmet laws applying
v Speeding to young bicyclists; none ofthese laws applies to all riders.
(www.helmets.org)
v Bicycle Crashes
v Pedestrian Crashes On average, one bicyclist is
involved in a crash with a
vehicle every other day in our

The formula for calculating the crash rate for a roadway segment is presented below.
The “Rate” ( R ) is expressed in crashes per Million Vehicle Miles Traveled (MVMT),
which is standard to the Traffic Engineering profession.
Where:
A = Average number of crashes along the study roadway per year
L = Length of roadway segment in miles
V = Average Daily Traffic Volume along the roadway
