1. 
Purpose.
A. 
New land developments and expansions of existing developments can have a significant impact on the transportation system, particularly if adequate planning and consideration of system improvements are not addressed. In order to ensure that a highway system can satisfactorily accommodate a proposed development,
B. 
A traffic impact study (TIS) may be required to analyze relevant impact issues. A TIS is a comprehensive study that analyzes all surface transportation modes that would be affected by a development, including pedestrians, bicycles, and public transportation services. The impact analysis area will generally be larger than just the immediate site.
C. 
The TIS concludes whether any transportation improvements are necessary to accommodate new and/or future traffic volumes generated by the proposed development or general growth of background traffic volumes. These improvements could include right turn lanes, left turn lanes, additional through lanes, acceleration lanes, bicycle lanes, bus stops, sidewalks, islands, medians, access control, traffic signals, removal and/or consolidation of existing approaches, etc.
D. 
The TIS documents the extent of the impact of the proposed development on the highway system, including trips added, resulting levels of service during weekday a.m., p.m. and Saturday (when necessary) peaks, and the need for auxiliary lanes or other special capacity or safety features. Required changes in traffic control, land use, access, pedestrian or bicycle usage must also be documented.
E. 
Additionally any changes effecting safety or traffic operations on the Township or State highway system including, but not limited to, striping, channelization, medians, islands, signalization and/or changes in access, shall be documented by the developer to show that all adjacent and/or affected property owners and businesses have been contacted and the impacts to their property has been discussed. A list of the names and addresses of all adjacent and/or affected property owners and businesses that were contacted shall be included with the TIS.
2. 
When Required.
A. 
A TIS shall be required with the submission of a new site plan, preliminary subdivision plan for a new or expanded existing development, or an official zoning district map application. The TIS shall be submitted when the following are exceeded:
(1) 
Residential developments in excess of 20 dwelling units.
(2) 
Nonresidential projects in excess of 10,000 square feet of floor area.
(3) 
Any commercial project with drive-through service proposed.
B. 
Projects, other than residential single lot developments, with direct vehicular access proposed to Route 30, North George Street, Susquehanna Trail, Greenbriar Road, Roosevelt Avenue, Board Road, or Church Road.
C. 
Expansion to any existing use exceeding 5,000 square feet or increasing the square footage by 5,000 square feet or more if no traffic impact study has been approved for the use in the five-year period preceding the application for expansion.
D. 
In addition, a traffic impact study shall be prepared whenever either one of the following conditions exist within the traffic impact study area:
(1) 
Current safety or congestion problems exist in the local area, such as high-accident location(s), confusing intersection(s), or a congested intersection(s), which affects access to the development.
(2) 
The capacity of the existing roadway system to handle increased traffic volume, or the ability to improve the roadway system to handle increased traffic is limited.
3. 
Impact Analysis Area.
A. 
There are several thresholds that must be analyzed to determine the scope of study area for each project. The thresholds are based on the number of trips to be generated in a twenty-four-hour period, which are referred to as average daily traffic volumes (ADT). In any event the applicant shall contact the Township to obtain concurrence for the level of study.
(1) 
Level I (0-200 ADT). Include each access point to the development including public streets/roadways, joint permanent easements and private driveways. A Level I study is generally required for larger residential subdivisions, small office developments or smaller commercial developments.
(2) 
Level II (201-3,000 ADT)-Level II (200-3,000 ADT). Include each access point to the development including public streets/roadways, joint permanent easements and private driveways. In addition, the study shall include the first major intersection beyond each site point of access. Major intersections are intersections controlled by traffic signals or stop signs and could include driveways. If there are no nearby major intersections Township staff will determine the extent of the study area. If a freeway interchange is nearby the project site to be developed it shall be included in the study. This level of study is commonly required for moderately sized commercial developments and larger office complexes.
(3) 
Level III (More than 3000 ADT). Level III studies shall include each access point to the development including public streets/roadways, joint permanent easements and private driveways. In addition, the study area shall include at least the first major intersection beyond each site point of access and any intersection beyond that that will increase by 100 or more peak directional trips generated by the development. In any event the exact area to be studied shall be determined by Township staff with input from the preparer of the study. Level III studies are usually warranted only with very large mixed-used and commercial developments.
4. 
Who Should Prepare Transportation Impact Study. Traffic impact studies shall be prepared under the supervision of qualified and experienced transportation professional that has specific training in traffic and transportation engineering and planning and several years of experience related to preparing transportation studies.
5. 
Context and Framework.
A. 
Existing Conditions.
(1) 
Collect baseline data including manual turning movement counts at each intersection and automatic traffic recorder (ATR) counts on each road segment. Include vehicle classification and speed analysis. Consideration must be given to the time of year the counts are performed and adjusted accordingly. Data will not be accepted if it is older than two years.
(2) 
Collect crash data.
(3) 
Collect geometric information at each intersection including primary traffic control devices, signs and pavement markings. Obtain traffic signal plans for each signalized intersection to determine signal operation, phasing and timing. Also to determine if the signal is interconnected and coordinated. If a signalized intersection is included in the study area and it is interconnected and coordinated, all intersections in the system must be included in the study.
(4) 
Photographs of each intersection and of other pertinent geometric conditions must be obtained and included in the study.
(5) 
Determine if there are other developments that have either been approved for development or are under development that need to be included as background data.
B. 
Projected or Non-site Traffic.
(1) 
Estimates of non-site traffic are required to complete the analysis of horizon-year conditions. These estimates characterize the "base" conditions-that is, without the subject site being developed.
(a) 
Through traffic consists of all movements through the study area, without either an origin or a destination in the study area (sometimes referred to as "background traffic").
(b) 
Other development traffic consists of other developments in the study area, with an origin and/or destination in the study area (sometimes referred to as pipeline development).
(2) 
Methodology of projecting non-site traffic.
(a) 
Build-up method, using specific developments.
(b) 
Use of area or sub-area transportation plan modeled volumes.
(c) 
Trends or growth rate method.
C. 
Future Conditions. Analyze future base conditions to provide assessment of how traffic will operate in the study horizon year without the study site being developed as proposed.
(1) 
The analysis shall be prepared for the anticipated opening year of the development, assuming full build-out and occupancy.
(2) 
A second analysis shall be prepared for the opening year plus 10 years. This shall be referred to as the horizon year.
D. 
Site Traffic Generation.
(1) 
Estimate the amount of traffic to be generated by the proposed development for both the peak hours of the adjacent street and the peak hour of the generator. Use of the Institute of Transportation Engineers (ITE) Trip Generation Manual is recommended.
(a) 
Collect additional data if:
1) 
The study site is not compatible with the ITE land use code definition;
2) 
There are only one or two data points (preferably if there are five or fewer data points);
3) 
The independent variable does not fall within the range of data; or,
4) 
Neither the weighted average rate line nor the fitted curve falls within the data cluster for the size of this specific development.
(2) 
Use the regression equation when:
(a) 
A regression equation is provided;
(b) 
The independent variable is within the range of data; or,
(c) 
Either the data plot has at least 20 points or the correlation coefficient R2 > 0.75, equation falls within the data cluster in the plot, and standard deviation > 110 of the weighted average rate.
(3) 
Use the weighted average rate when:
(a) 
There are at least three (preferably six) data points;
(b) 
The independent variable is within the range of data;
(c) 
The standard deviation < 110% of the weighted average rate;
(d) 
R2 < 0.75 or no equation is provided; or,
(e) 
The weighted average rate falls within the data cluster in the plot.
E. 
Site Traffic Distribution and Assignment. Distribute the site generated traffic onto the roadway network utilizing one of three methods, including:
(1) 
Analogy.
(2) 
Model.
(3) 
Surrogate data methods.
F. 
Site Access and Off-Site Improvements.
(1) 
The preferred level-of-service in Manchester Township is LOS D. All intersections and their approach movements should operate at or above this level-of-service. If they do not operate at LOS D or better then improvement mitigation measures must be recommended to improve the LOS to D or above.
(2) 
Any new access, new intersection or addition of a leg to an existing intersection must operate at a level-of-service C or better.
(3) 
Roadway segment analysis must also be provided. The degree of adequacy of roadway segments between intersections is directly related to the number of traffic lanes, intersection spacing, vehicular queuing requirements at successive intersections and weaving or merging requirements.
(4) 
Cost opinions for all improvements must be provided. The cost opinions must include design, construction, right-of-way, utilities, inspection and any other cost to complete the recommended improvement.
(5) 
An agreement between the developer and the Township must be:
(a) 
Drafted indicating:
1) 
The off-site intersections projected to be improved.
2) 
The percentage of traffic (responsibility) of the proposed development on that intersection.
3)
