Measuring Vehicle Turning Emissions and Fuel Consumption in
Residential Areas
Principal Investigator: Dr. Fengxiang Qiao
Sponsoring Agency: Texas Southern University Seed Grant
Period:
February 1, 2006 ~ August 31, 2006
Research Abstract:
More deceleration and acceleration actions
will be existed when turning (either left-turn or right-turn) while
compared with the through movements. This is also true when driving
through the traffic bumps within residential areas. Extra emissions
will be expected when vehicles make turnings and drive through the
traffic bumps. These possible extra emissions are one of the direct
sources that will impact negatively to the overall environment
within the residential areas.
Due to the variability of emissions from
different vehicles on different runs, existing traffic simulation
and evaluation models are not able to yield the reasonable emission
estimations under these cases. Therefore, the impacts of the vehicle
emissions by turning and bumps in residential area are still not
properly quantified till now.
The newly developed Potable Emission
Monitoring System (PEMS), which TSU Department of Transportation
Studies has purchased through another project, is capable of
providing the second-by-second vehicle emission data via on-road
testing. The Principle Investigator had obtained enough experiences
on collecting the real time vehicle emission data as well as the
associated vehicle activity data and GPS (Global Positioning System)
data.
By making full use of the PEMS equipment, it
is predictable that the vehicle turning emissions within residential
areas will be tabulated, and the impacts of vehicle turning
emissions to the residents and surrounding areas will be evaluated.
The hypothesis to be tested is: vehicle
turning emissions have special impacts to the surrounding
environments and residents that can be better captured through
on-road tests than through the traditional lab-based computerized
models.
The goal of this research is to analyze the
characteristics of vehicle emissions when making turning and passing
bumps within the residential areas. To achieve this objective, the
research will:
a. synthesize a reasonable testing plan and
select proper test beds;
b. collect on-road vehicle emissions within
residential areas when turning and passing bumps;
c. develop a suitable procedure to analyze
the collected on-road emission data; and identify the
characteristics of vehicle emissions within residential areas;
d. associate the collected emission data with
the GPS data as well as model any possible relationships; and
e. compare the identified emission properties
with what the other models estimates.
