of existing traffic capacity conditions, accidents that have occurred
over the past five years should be inventoried and analyzed. The inventory
should be conducted for both intersections and road segments, i.e.,
"midblocks." Further, accident analysis, i.e., frequency of accidents
per vehicle miles traveled, should be conducted for the road segments
or "midblocks." The analysis segments will identify safety-deficient
segments within the study area roadways. Recommendations for the improvement
of safety deficient segments should be offered in the study.
(d)
Future trip projections.
[1]
Estimation of vehicular trips to result from the proposed development
shall be completed for the average daily, peak highway hour(s) and
peak development-generated hour(s). Vehicular trip-generation rates
to be used for this calculation shall be based on ITE's "Trip
Generation Manual," current edition, and/or data collected from sites
with similar trip generation characteristics. Also, provide an estimate
of anticipated truck volumes. These development-generated traffic
volumes shall be provided for the inbound and outbound traffic movements
and the reference source(s) and methodology followed shall be documented.
All turning movements shall be calculated. These generated volumes
shall be distributed to the study area and assigned to the existing
roadways, and key intersections throughout the study area. Truck volumes
expressed in the percentage of total volume should be shown as a data
entry in the capacity analysis results provided in the appendixes
of the study.
[2]
Provide a detailed distribution and assignment of any pass by
trips. Document all assumptions used in the distribution and assignment
phase in a manner which permits the duplication of these calculations.
Pedestrian volumes shall also be calculated, if applicable. If school
crossings are to be used, pedestrian volumes shall be assigned to
each crossing. Any characteristics of the site that will cause particular
trip generation problems shall be noted.
[3]
Background growth and projected traffic from adjacent land development
shall be included in the projection of future traffic.
(e)
Transportation impacts.
[1]
The study area roadway network is to be analyzed for safety
and capacity sufficiency for future network conditions without the
proposed development and future network conditions with the proposed
development. For each of these conditions, the following analyses
shall be completed. For each of these conditions, the following analyses
shall be completed:
[a] Mainline ADT volumes and turning movement volumes
for all key intersections within the study area will be determined
for the AM peak hours, PM peak hours and the proposed development
peak hours, if other than either the AM or PM peak hours of the network.
[b] The effectiveness of the traffic signal control
at all key intersections will be evaluated by approach in terms of
vehicle stops and delays.
[c] Gap studies will be conducted at the proposed site
access points to evaluate the need for signal control, turn prohibitions
or additional site access points to reduce the left-turn volume from
the site driveway(s).
[d] Queue length studies will be completed to evaluate
the potential for a backup of traffic from controlled intersections,
which could impact other intersections including access points to
the proposed development.
[e] An analysis of the volume and capacity of the network
and all key intersections will be conducted utilizing the most current
"Highway Capacity Manual" procedures. Levels of service will be determined
and documented.
[2]
The analysis of the future conditions without the proposed development
will document the adequacy of the study are network to accommodate
the traffic-in the design year(s) without the proposed development.
This analysis must include a full consideration of all committed roadway
improvements to the study are network when determining the expected
levels of service.
[3]
The analysis of the future conditions with the proposed development
will document the impacts created as a result of the development.
(f)
Conclusions and recommended improvements. Levels of service
for all roadway segments and key intersections shall be presented
in tabular and graphic form. All roadway segments and/or key intersections
showing a level of service below D for roadway segments, signalized
intersections, and unsignalized intersections shall be considered
deficient, and specific recommendations for the elimination of these
deficiencies shall be listed. This listing of recommended improvements
shall include, but not be limited to, the following elements: internal
circulation design, site access location and design, external roadway
and intersection design and improvements, traffic signal installation
and operation, and transit design improvements. All physical roadway
improvements shall be shown on the final plan. Existing and/or future
improvement transportation service shall also be addressed. For each
recommended improvement, provide a schematic drawing of existing and
proposed conditions as well as a narrative description of the improvement,
including the cost and funding method of the improvement, and the
implementation schedule for the improvement.
F. Final report. A final report must be prepared to document the results
of the traffic study and the recommended improvements to accommodate
the projected traffic due to the proposed development. Provide an
executive summary, which provides a concise description of the study
area, results of the traffic analyses, and any recommended improvements.
The presentation of data and analyses results should be accomplished
on either schematic diagrams of the study area, or through the use
of charts and/or tables. All sources of data and methodologies which
were used in the study (including computer programs) must be properly
referenced and documented. Any modifications to the referenced procedures
must be properly documented to enable a review of the appropriateness
of the modification. Provide all computer output and calculations
in appendices.
