Methodology

BRT Network Analysis
Description
Identify which stations
have parking facilities.
The purpose of this is to
know which are going to
be the stations of interest
for the analysis.
Analysis
Capacity and average
occupancy of each station
is determined by counting
the amount of bicycles
that use the facility in a
given time. Information
from Transmilenio.
Methodology

Survey and Data Collection
Description
The second step has the purpose
of knowing the points of origin
of travelers that use the facility,
their income, their age, basically
all kind of demographic and
social information of users.
Surveys at stations are proposed to be
divided into two
Methodology
-
Distance traveled
Bicycle travel time
Bike paths used for reaching the station
Perception of users in relation to the quality of the
bicycle parking service
-Demographic information:
Where you live
Where you work
Stratum
Number of children
Marital status
Profession
Salary
-Information provided by the
operator of the system:
Capacity of the system
Daily occupation
Explanation of the security system
Reports of damages
Satisfaction surveys
Daily users
Gender of users
Methodology

Spatial Catchment
Description
In this step it is proposed to use GIS
tools to determine spatial relationships
between all these factors.
Tools commonly used in this
step are buffering, clipping,
od matrix and others that are
commonly used in GIS spatial
analysis.
Results
As a result of this step, we found the
key factors that determine the
occupancy of the parking facility, so
we have enough data to create the
methodology that should be used to
design properly parking facilities in
any BRT system.

 Connectivity problems.
 According to the 2011
mobility survey 5% of
total daily trips in the city
are made in bicycle.


Application of Methodology in one Station with
Bike Parking
Portal Sur was selected
because this station has the
most bike parking
occupancy, but its capacity
is not enough to supply the
demand, also because of
the great amount of
passengers that arrive to
the station.
Identification of the places where is the bike parking, the
capacity and occupation

The occupation of the bike parking depends on
three important factors
o

o
The total inflows to the analysis station
Areas of low, medium and high stratum near the station
The coverage of the existing feeder routes

Create an equation system in order to find the
coefficients that will help us designing the capacity
needed.
By solving this system of equations, we create a
multi-criteria methodology of capacity design.

Conclusions




The methodology used in this paper is can be used by anyone
interested in designing bicycle infrastructure at any BRT system in the
world.
A disadvantage that the methodology may have is that although we
have feeder buses routes, we only takes into account the number of
routes, since feeder buses routes are difficult to quantify.
In the specific case of the design of bike parking for Transmilenio
system in Bogota, it was found that the location and capacity of the
parking infrastructure is not consistent with the demand and,
therefore, infrastructure is not properly used.
The major limitation was that small number of existing parking
facilities, which delayed and complicated the process of analysis.
