(5) A summary, table, and diagram of all capacity analyses by location and time period shall be provided. The table shall include Level of Service (LOS), volume to capacity (V/C) ratio, density in passenger cars per mile per lane, and delay in seconds for each movement of each analyzed intersection, ramp and/or roadway, as applicable.

3. Trip generation, distribution, modal split and assignment:

i. A trip generation analysis shall be conducted using the procedures described in the ITE Trip Generation Handbook, Second Edition, incorporated herein by reference, as amended and supplemented, a copy of which can be obtained from the Institute of Transportation Engineers, 525 School Street, S.W., Suite 410, Washington, DC 20024. Trip generation shall be calculated using the trip generation rates and/or formulas described in the ITE Trip Generation manual referenced in (a)2 above. All methods, land use codes, rates and formulas used from the manual shall be noted, including appropriate edition and page number. Alternative trip generation from surveys may be used if the process and sources are documented and determined adequate by the NJMC. All trip generation methods, including trip reduction credits such as pass-by, transit, or internal capture, shall be subject to NJMC approval. All trip generation methods shall include written justification, including illustrations.

ii. A tabular summary shall be provided indicating the entering, exiting, and total trips for the peak hours determined by the NJMC.

iii. Trip distribution shall be determined by using a gravity model method approved by the NJMC that replicates the flow of traffic by trip origin and destination. Trip distribution documentation including rationale, procedures, and calculations shall be described and illustrated in the TIA.

iv. The modal split, or mode choice, shall be provided describing the means of transportation used, including personal vehicle, transit, walking, or other means. The modal split shall be provided for each existing and future condition and listed by percentage of mode type. The TIA shall provide the source of the modal split information and indicate the relevance of this data to the proposed site development or project. The modal split shall be subject to approval by the NJMC.

v. Trip assignment shall be provided by showing how the trips were assigned on the transportation network for the future conditions. The applicant shall describe and illustrate the methodology used assigning the trips.

vi. A total site traffic volume diagram shall be provided, including each peak hour analyzed.

4. Future no-build conditions:

i. The future no-build conditions that are projected without the proposed development shall include the following:

(1) The identification of any development, other than the proposed project, using the same existing or proposed roadway network as the project in question that is projected to be built by the same proposed build year(s), inclusive of all phases, and the resulting trips. The trip generation of the development shall be calculated in accordance with (c)3 above;

(2) A background growth rate, compounded annually, determined from the Annual Background Growth Rate Table, published by the New Jersey Department of Transportation (NJDOT), April 2007, incorporated herein by reference as amended and supplemented, and applied to the existing traffic volumes of the study area.

(1) Any roadway, ramp, or intersection that exceeds a LOS "D" or degrades the no-build LOS by more than one LOS letter grade shall be subject to mitigation measures.

(2) Any new roadway, ramp, or intersection shall be designed to operate at a LOS "C" or better.

(3) If the project is built in multiple years, build and mitigation conditions shall reflect the multiple build years separately.

(4) Proposed on-site and off-site transportation improvements supplemental to the no-build or proposed build transportation improvements shall be described and illustrated with a detailed conceptual design showing all geometric elements and dimensions, and detailed cost estimate.
