of approach speeds by lane, roadway classification, speed limit,
under- and over-saturated traffic conditions, and area type.
Approach speeds on "non-posted" roadways and on roadway
with speed limits of 35 mph (56 km/hr) or less. There is need for
development of supporting information to determine approach
speeds for driveways, alleyways, short approaches, entrances
to new developments, and other "non-posted" roadways. The
proposed research should determine values and guidance for
practical application for these types for roadways. Research
should also examine the significance of these potential effects
and measures of effectiveness associated with approach speeds
and intersection entry under yellow or red signal indications.
Easy-to-implement method to determine the length of travel
path through intersections for turning movements and
complex intersection geometries. Vehicles making turning
movements or moving through complex intersection geometries
typically do not follow circular paths. Research should also
examine the significance of these potential effects and whether
they could be practically applied to change and clearance
interval calculations.
Effect of weather conditions. Many jurisdictions implement
special timing plans for inclement weather situations. An
additional study opportunity could examine the significance
of these potential effects and whether they could be practically
applied to change and clearance interval calculations
or assumptions.
Detectors. Additional study would be useful on the effect of
detector configuration in determining approach speeds in such
cases as multi-detector designs for high-speed approaches, advance
end-of-green warning, or dynamic red clearance extension.

If you are an educator or student in a university looking for a
good research topic or a research sponsor seeking useful research
to fund, the list above offers a wide range of ideas that would be
valuable to both the transportation profession and the safety of the
traveling public. itej
