Services
Quality Counts provides many services, from the standard available services, to
core and special services:
STANDARD SERVICES
Manual Turning Movement Counts
Manual Turning Movement Counts record vehicle turning movements at an intersection
on 5-minute intervals over a 2-hour period. Pedestrian movements and heavy vehicle
percentage are also recorded. The pedestrian movements will be recorded as the number
of pedestrians crossing each intersection approach. The count request should identify
the intersection, time period and day of the week customers wish the count to take
place.
Gap Studies
Gap Studies measure the number of available gaps in the traffic stream for use by
vehicles or pedestrians at unsignalized intersections. Gaps can be recorded as either
single direction or bi-directional. Single direction gaps find the gaps in one travel
direction only, while bi-directional gaps occur when the roadway is clear in both
travel directions. Gaps are reported as the number of gaps that occur during the
studied time period for all gap lengths reported at 0.5-second increments. Count
request should specify the location, the time period and day to be studied, as well
as whether gaps should be recorded directionally, bi-directionally or both.
Road Tube Studies
Road Tube Studies produce several types of information about the vehicles passing
on the selected roadway. In addition to vehicle volume, tubes can be used to gather
speed and vehicle classification (using the FHWA's 13 types) information. Typical
studies range from 24 to 48 hours, but may be requested for as long a period as
needed. Data is summarized and delivered in Excel and PDF formats.
Parking Accumulation Studies
Parking Accumulation Studies identify the peak parking demand of a land use. The
total number of vehicles parked on a site is recorded every 30 or 60 minutes over
a time period that is estimated to contain the peak parking demand. The request
for data should include the site location, the time interval for recording parking
occupancy and the time period and day to be studied. The person requesting the study
must obtain permission from the landowner/leaseholder to conduct the study on the
site.
Pass-by/Internal/Diverted Trip Surveys consist of a series of questions for people
arriving at a land use (typically some type of retail use). The questions are intended
to quantify the percentage of site users who will be making additional stops within
the development (internal trips), who would have passed by the site anyway (pass-by
trips), who were driving anyway and changed their route to visit the land use (diverted-linked
trips), or who have made a trip for the sole purpose of visiting the land use being
surveyed (primary trips). The request for surveying should provide a survey form
(Quality Counts can help develop survey forms) and specify the location of the site,
time period and day of the week for the surveys. The person or firm requesting the
count will also be responsible for obtaining permission from the landowner/leaseholder
to conduct the survey on the site. Quality Counts will provide personnel to ask
the survey questions and can provide data reduction services if requested.
Passenger Car Occupancy Surveys
Passenger Car Occupancy Surveys determine the average occupancy for vehicles on
a certain roadway or visiting a single site. The data is obtained by observation
of vehicle occupancies as vehicles pass a fixed point. In addition, vehicle occupancy
information can also be obtained as part of an Internal/Pass-by/Diverted-linked
Trip Survey. The count request should identify the location for the survey and the
time period and day the survey should take place. If the survey requested requires
entry to private property (e.g. an on-site vehicle occupancy survey), the person
requesting the survey will be responsible for obtaining permission from the landowner/leaseholder
to conduct the survey.
Pedestrian Counts
Pedestrian Counts consist of the number of groups of pedestrians crossing the roadway,
and the number of pedestrians in each group. The numbers crossing will be reported
by direction in 15-minute increments during the count time period. The count request
should identify the location, time period and day the count should take place.
