2 CEQR Overview/Process Updates to Transportation ti Chapter HCM Model Calibration Tips and Tricks 2

3 NEPA 1969 Requires to evaluate environmental consequences of proposed projects and consider alternatives CEQR 1973 Mayor s Executive Order No. 87 (environmental review of major projects) Mayor s Executive Order No. 91 in 1977 (established CEQR) SEQRA 1975 Article 8 of NYS Environmental Conservation Law NYSDEC promulgated regulations to guide the SEQRA review process (6 NYCRR 617) 3

4 CEQR City Environmental Quality Review Process for review of proposed discretionary actions Purpose is to identify the potential effects on the environment Requires agencies to assess, disclose and mitigate impacts EAS & EIS are disclosure documents used to inform decisions 4

5 DISCRETIONARY, not ministerial i i May affect environment Executed, funded, and/or approved by a city agency Adoption of rules, laws, codes, etc. 5

6 Discretionary Actions Rezoning/Mapping Adoption of regulations Site selections Permits (marine transfer station) Ministerial Actions Building permits Certain licenses 6

7 Type II Type I Unlisted No environmental review is required Actions have no significant Impacts City uses 6 NYCRR Part 617 list Likely Requires an EIS Agencies may add other actions An action that is not Type I or Type II EAS is required EIS may be required 7

8 Lead agency one that can approve, fund or undertake an action and is principally responsible for the environmental review Involved agency one that can approve, fund or undertake an action Interested agency one that lacks jurisdiction to approve, fund or undertake an action, but requests or is requested to participate because of special concerns or expertise 8

The truck trip generation rates are based on the use of a directional split. 15

16 Traffic Counts Nine-day ATR counts including two weekends Pedestrian verification counts Bicycle - part of classification counts Passenger Car Equivalents (PCEs) Table 16-3 Table 16-3 Passenger Car Equivalents (PCEs) Vehicle Type Vehicle Class PCE Factor Personal Auto Passenger Car Trucks/Buses with 2 Axles and Light Truck 1.5 waste collection vehicles Trucks/Buses with 3 Axles Medium Truck 2.0 Trucks with 4 or more Axles Heavy Truck

17 NYMTC Best Practices Model For projects that would cause major changes in regional and citywide travel patterns. Other Analysis Tools/Methodologies Other software or simulation i models may be employed if: Compatible with air quality models; Provides the same performance measures as the HCM outputs (i.e., levels of service, delays, etc.); and, Demonstrates consistency with the traffic engineering principles and theories of traffic flow as described the HCM. Requires NYCDOT approval prior to utilizing new analysis tools/methodologies 17

18 Person-delay calculation Accounts for the benefits related to the implementation and/or improvements of surface transit (i.e., BRT, SBS) projects. Lower Annual Background Growth Rates Table 16-4 Annual Background Growth Rates Section of the City 1 to 5 years Year 6 and beyond Manhattan 0.25% 0.125% Bronx 0.25% 0.125% Downtown Brooklyn 0.25% 0.125% Other Brooklyn 0.50% 0.250% Long Island City 0.25% 0.125% Other Queens 0.50% 0.250% St. George (Staten Island) 0.50% 0.250% Other Staten Island 1.00% 0.500% 18

19 Determination of Significant Impacts Traffic Eliminated one second impact criteria under LOS F Modified language for Impacts to be considered mitigated Pedestrian Redefined impact criteria for pedestrian elements (i.e., crosswalk, corner, and/or sidewalk) based on a sliding scale for CBD and non-cbd areas 19

21 Parking Inability of a proposed action or the surrounding area to accommodate a project s future parking demand is considered a shortfall not an impact Parking shortfalls in Zones 1 and 2 are not considered significant due to the magnitude of available alternative modes of transportation 21

22 Street Design Manual Identification of feasible and practical mitigation Guided by City DOT s 2009 Street Design Manual Table 16-8 Describes typical traffic mitigation measures The approvals required before including any mitigation in the EIS NYCDOT Street Design Manual s policies that guide the design of certain mitigation/improvement measures 22

23 Table Type of measure Approval required Must follow 511. Low-cost, readily implementable measures Signal phasing and timing modifications DOT Signals Division Parking regulation modifications DOT Borough Engineering Lane restriping and pavement marking changes DOT Highway Design and Construction Street Design Manual Street direction and other signage-oriented changes NYC DOT Traffic Planning Division, Highway Design and Construction, Borough Engineering 512. Moderate-cost, fairly readily implementable measures Intersection channelization improvements DOT Highway Design and Construction Street Design Manual Traffic signal installation DOT Signals Division Intersection Control Analysis 513.

DOT Highway Design and Construction, Street Design Manual 514. Enforcement Measures Traffic enforcement agents NYPD 515. Trip Reduction or Travel Demand Management Measures Carpooling and vanpooling Staggered work hours and flextime programs Improved bus service New transit services Telecommuting Bicycle/Pedestrian facilities NYS DOT (for State-owned highways) h MTA New York City Transit DOT Highway Design and Construction (if geometric changes are proposed) MTA New York City Transit DOT Office of Bicycle and Pedestrian Programs Street Design Manual (if geometric changes are proposed) 23

24 Minimum Pedestrian Time Pedestrian Walking Speed An average walking speed of 3.5 fps For schools and senior areas, 3.0 fps should be used 24

25 Traffic Monitoring Plan Medium- to large-scale developments that have identified unmitigatible impacts Projects that t propose capital improvements Helps verify the need and effectiveness of the proposed mitigation measures identified in the EIS New York City Local Law 24 (CRIA) A review process in the event of the closure of a publicly mapped street Community Reassessment Impact Amelioration (CRIA) statement is required if a street is closed for more than 180 consecutive days for which a permit from City DOT is needed One public forum must be held prior to the issuance of the CRIA/EAS/EIS 25

32 Trick #1 Meet with NYCDOT Determine required study locations Provide local knowledge Inform Any recent counts - TIMS Placement of ATRs Capture Demand 32

33 Tip #2 Volume Development New MTMC data and ATR data New and historical MTMC data Sinks and Sources Estimated/adjusted traffic volume Graphical presentation and quality check 33

34 Trick #2 Meet with NYCDOT Walk through your balancing/adjustments Peak hours in Manhattan 8:00 9:00 AM 12:00 1:00 PM 5:00 6:00 PM Validation (use historical data, other data) Be conservative and reasonable 34

35 TIP #3 - Signal Timings Official signal timing records Traffic signal timing verification Traffic Enforcement Agent (TEA) 35

36 Trick #3 Call NYCDOT Operational and geometric changes Verify before submitting to DOT May M need to change No-Build 36

37 TIP #4 - HCS Parameter Adjustments Factors and assumptions for HCS to replicate observed field conditions that are verifiable and quantifiable. Lane group s calculated volume to capacity ratio (v/c) should be less than or equal to 1.05 for existing condition. 37

38 Trick #4 Call/Meet NYCDOT Capacity analysis factor guidelines Discuss unique circumstances Document D all changes 38

39 NYCDOT HCS Guidelines Standing or Queued Vehicles Start-up Lost Time Traffic volumes Saturation Flow Rate Arrival Type Peak Hour Factor (PHF) Area Type Extension of Green Lane width Right-turn and left-turn factors Unmet Demand Right Turn On Red I-factor Conflicting Pedestrians Heavy vehicle percentages Bus Blockages Bus Lanes Parking Maneuvers 39

41 TIP #5 - Do not use new software until fully tested t HCS 2010 Experience 1. Opposing shared left-through lanes operating with permitted phasing (i.e. not split phase). 2. Unopposed left-turns on major streets. 3. Permitted double-left turns where one lane is a left-only lane and the other is a shared left- through h lane. 41
