Analysis Background The AKRF Team, in coordination with NYCDOT, coordinated with New York Metropolitan Transportation Council (NYMTC) MPO to obtain the latest version of the New York Best Practice Model (NYBPM). The AKRF Team used to the model to conduct a select link analysis (SLA) for three sections of the BQE to identify preliminary O-D patterns during the morning 6-10 a.m. and evening 4-8 p.m. peak periods for six directional links and extractions of O-D flows per peak period. The analysis summaries include the origins and destinations, O-D flows and percent shares by auto and truck vehicle classes. The three select link analysis sections of I-278 (Figure 1) were:
A. At Smith Street (Gowanus Canal) B. At Triple Cantilever Section C. At Vanderbilt Avenue (East of Manhattan Bridge)
Figure 1: I-278 Select Link Analysis Sections
The detailed O-D tables were summarized by two zonal tiers: (1) NYMTC regional counties and (2) NYC neighborhoods. The first (higher) aggregation level was the 28 counties covered by the NYBPM, plus all external zones grouped together into a 29th category. The second (finer) aggregation level uses the NYCDCP’s neighborhood delineated spatial boundaries. There are 195 neighborhood spatial “zones” in the five boroughs of New York City. For this finer level of aggregation, county-level aggregations were maintained in Manhattan, The Bronx, and Staten Island, as well as outside New York City, while origins and destinations in Brooklyn and Queens were summarized at the NYCDCP neighborhood-level. In total, this second aggregation level has a total of 136 geographic areas.

The O-D tables are given by autos, trucks and total autos plus trucks. The resulting 72 O-D tables were used to generate a summary presentation including percentage breakdowns and detailed figures for the Cantilever Section in particular.
Summary of Key Findings Eastbound Cantilever Section On the cantilever section, the following eastbound trip distributions were identified during the modeled 4-hour morning period (6-10 a.m.): Autos by Origin Trucks by Origin
7% of autos are from NJ origins to NYC destinations, of which 4% are destined for Manhattan
27% of autos are from S.I., of which 10% are destined for Manhattan, 11% to Queens and 4% to Brooklyn
The largest share of autos, 58%, are trips from Brooklyn to destinations within NYC, with 19% to the Bronx, 12% to Manhattan, 10% to Queens and 17% within Brooklyn

Figures 2 and 3 provide a view of morning eastbound auto and truck distributions, respectively, approaching and departing the cantilever section. The percentages listed in the figures represent the share of BQE cantilever traffic that passed each labeled point approaching (blue) or departing (red) the cantilever section (yellow). The figure is to illustrate primary routes to/from the select link.
