All traffic impact studies submitted to Regional Planning shall be prepared in accordance with the applicable guidelines of Traffic Access and Impact Studies for Site Development-A Recommended Practice, Institute of Transportation Engineers, Washington, D.C., 1991. Additions to the following requirements may be made by Regional Planning and relief from these requirements may be granted by Regional Planning upon a written request by the study preparer.
A. Scope of study. The scope of the traffic impact study will be consistent with the guidelines of ITE's Traffic Access and Impact Studies for Site Development - A Recommended Practice Chapter 2, subject to approval by Regional Planning. It is strongly recommended that the traffic impact study preparer confirm the scope of work with Regional Planning prior to undertaking the study.
(1) Locations. At a minimum, all existing and proposed site access points, significant intersections and the nearest signalized intersection on each street serving the site if within one mile of the site shall be included in the study.
(2) Peak periods. A.m. and p.m. peak periods shall be studied, along with Saturday peak periods for retail commercial projects.
(3) Study horizon. The following time horizons shall be used for analysis of peak period conditions at all study locations.
(b) Future no-build conditions, i.e., all background and other proposed development traffic [§
86-711B(4)(b)] and not including traffic generated by the proposed subject development.
(c) Future build conditions, i.e., no-build conditions, plus development traffic.
B. Content of study. The content of the traffic impact study shall be consistent with the applicable guidelines of ITE's Traffic Access and Impact Studies for Site Development - A Recommended Practice, Chapter 10.
(1) Executive summary. The traffic impact study shall include an executive summary outlining the purpose of the report and study objectives and a description of the site location and study area, proposed development, principal findings, conclusions and recommendations.
(2) Existing conditions. The existing conditions inventory shall include at a minimum, peak-period turning movement counts, adjustment factors, if applicable, roadway geometry and traffic control devices, including those at nearby intersections or driveways, transit service and other deemed important by the study preparer or required by the Office of Policy, Planning and Economic Development. Volume-capacity analysis of existing conditions may be provided here, or in the analysis section of the study, at the preparer's discretion.
(3) Proposed development. The study shall provide a general description of major proposed developments in the vicinity of the site and a detailed description of the subject site, including land use and intensity, location, site characteristics, timing and phasing (if applicable).
(4) Future conditions. The traffic impact study shall include a description of anticipated future land use, road network and traffic conditions consistent with the applicable guidelines of ITE's Traffic Access and Impact Studies for Site Development - A Recommended Practice and shall include, at a minimum, the following information:
(a) Transportation system. Committed or reasonably anticipated changes to the local roadway or mass transit network shall be incorporated into the analysis [§
86-711B(5)].
(b) Non-site traffic. Non-site background traffic forecasts shall be provided and shall be consistent with the applicable provisions of ITE's Traffic Access and Impact Studies for Site Development - A Recommended Practice, Chapter
4.
(c) Site traffic. Site traffic forecasts shall be provided and be consistent with the applicable guidelines of ITE's Traffic Access and Impact Studies for Site Development - A Recommended Practice, Chapters 5 and 6, Site Traffic Generation and Site Traffic Distribution and Assignment.
(5) Traffic analysis. All study locations shall be analyzed for all peak periods in accordance with ITE's Traffic Access and Impact Studies for Site Development - A Recommended Practice, Chapter
7. This section shall include an evaluation of intersection and link capacity, safety, sight distance, parking and on-site circulation as they relate to the operation of all driveways intersecting a County road.
(6) Improvement analysis. The traffic impact study shall include recommendations for improvements required under build conditions to achieve the level of service standards described in this section.
(a) Signalized intersection standards for County road approaches anticipated to operate under no-build conditions at:
[1] LOS A or B, deterioration to LOS C will be allowed in the build condition;
[2] LOS C or D, deterioration of one-half of LOS D (7.5 seconds) will be allowed in the build condition, provided that the build LOS remains at D or better (less than 40.0 seconds);
[3] LOS E or F, no deterioration will be allowed. Delay shall be used to compare no-build and build conditions when the no-build volume/capacity ratio is less than or equal to 1.2. Volume/capacity ratio shall be used to compare the no-build and build conditions when the no-build volume/capacity ratio exceeds 1.2.
(b) Unsignalized intersection standards. All unsignalized intersections or site access points anticipated to operate a LOS E or F under build conditions shall be subject to an analysis of signalization or other mitigation techniques. The analysis shall consider such factors as traffic signal warrants, impacts on major street progression or other factors deemed relevant by the analyst or Regional Planning.
(7) Certification. All traffic impact studies submitted to Regional Planning shall be signed and sealed by a professional planner or professional engineer licensed by the State of New Jersey.
