As final year civil engineering project ,we conducted a research on BRT feasibility inside kathmandu valley on GODAVARI TO BUDHANILKANTHA .As being bounded by time and resources we used following techniques and methods for analysis .
the
following methods could be used for analysis of brt and some of them couldn’t
be used on our
1.DESTINATION SURVEYS
The purpose of destination surveys is to collect
information on from where and to where journeys are being made. Destination
surveys are carried out in connection with regional traffic surveys and, for
example, for the needs of traffic system planning on our case BRT could be
considered.
They are also done for specific projects, for example in
connection with big and practical needy projects. The surveys are usually done
by means of roadside interviews or direct field involvement.
Destination surveys can give us following types of traffic information:
·
point of departure and destination (Godavari to budanilkantha ,
location)
·
journey time and length of journey
·
type of vehicle( 4 wheelers considered)
·
number of passingers
·
purpose of journey ( we asked questions)
Destination surveys are carried out as sampling surveys.
In order to extend the sampling, a traffic count is done daily at the same time
as the interviews and we choosed peak hour and off peak hours. As we were
supervised we conducted the survey under guidance of Er.Hemant Tiwari.
2.SPEED INFORMATION
we carried out vehicle speed measurements on the road and proposed
routr. Vehicle speed information can be measured by radar counter without
drivers noticing. Alternatively, a speed display board can be connected to the
measuring device, allowing the drivers of the vehicles to see their speed too.
The method of measuring speed information mentioned first can be used if, we
want to study the need to reduce driving speeds. Second one is effective and
efficient for our BRT analysis.
Due to resource
limitation we collected speed data without above techniquies . infact we use distance
covered and recorded time considering delays,jams and other factors. Though
this speed information about speed collection techniq is not accurate we don’t
have any othwer alternatives .
The following
information can be collected about the location:
·
total number of vehicles .
·
occupancy inside vehicles.( for trip prediction from govavari to
lagankhel and vice versa).
·
analyses of vehicle speeds and traffic volumes at specific
points.( we conducted by travelling in vechile for required times.
traffic studies for location of brt in ktm should include
followinh:
·
automatic traffic counts ( not possible with our fund provided by acem)
·
intersection counts ( visiting existing route Godavari to
budanilkantha )
·
speed measurements/surveys ( noting distance covered and time
without stoping vehicles)
·
mobile speed displays( can be used if resource is available )
·
noise level measurements/surveys ( not considered in ktm but
should be analyzed)
·
pedestrian and bicycle counts ( for dedicated lane ;though not
possible now)
·
axle weight analyses ( difficult to perform and bound of available resources)
·
destination surveys various techniques can be used and is applicable at some extenrt in our
route)
3.TRAFFIC VOLUME DATA
Traffic volume data is usually needed for planning and
monitoring measures. Our research includes different traffic volume surveys,
such as:
·
Vehicle counts
·
Pedestrian and bicycle counts ( we consider people and bicycle moving outside main lane )
·
Occupancy inside 4 wheeler in our proposed route ( Godavari to
budanilkantha)
·
Densly Trip generating
areas. (main stations)
Parking area surveys ( for possibility of dedicated lane and traffic
management.
If funding is extensively available the following could give effective output. since our research is time bound and resource limited we conducted with available techniques and methods.
