Medallion Taxi GPS

� GPS in over 13,000 taxi cabs (TLC

vehicles)

� Each fare trip is recorded

� Since 2008, nearly 1 billion records

have been stored and analyzed

� The data provide numerous

insights:

� Spatial and Temporal Trip

Distributions

� Origin-Destination Patterns

� Trip Length and Travel Times

� Intra-zonal, Inter-zonal and

corridor-wide travel speeds

5% 13%

7% 45% 30%

MTA/NYCT Bus Time

� GPS devices on approximately 115

routes (1,800 vehicles) to date

� Currently over 2 million records

per day

� Increasing to entire bus fleet

� Gathers bus activity, position and

speed at 30-second frequency

� Includes data for corridors and

crossing where speed data are not

typically gathered

� Coverage of the Outer Boroughs

(all of Staten Island and the Bronx

to date)

� Specific vehicle, route and time-of-

day data can be isolated and

analyzed

MODELING

PLATFORM

Modeling Platform

• A base network and series of sub-

networks that can be a cornerstone

for analysis, decision-making and

outreach

• “Step-down” from the regional

travel demand model (NYBPM)

• Link travel demand forecasting

and traffic operations; capture mode

shift

• Critical corridors and area detail as

needed

• Align program and project

development processes

• Provide the basis for a decision-

support system for interagency

collaboration (NYCDOT, NYSDOT,

PANYNJ, MTA, etc.)

O-D DEMAND ESTIMATION

• Subarea Extraction

NETWORK COMPLEXITIES

• Congestion

• Grid structure; route choices

• Parking

• Pedestrians and bikes

• Buses

• Taxis

• Truck deliveries

• Traffic enforcement agents

• Traffic signal coordination

• Managed-use lanes (Bus,

HOV)

• Bridge and tunnel operations

• Reversible Lanes

• Maze of approaches

• Time of day variations

MODELING APPROACH

• Combination of static routes as input to DUE with limited "one-shot" DTA stochastic route choice

• Custom feedback of paths as an initial starting point for the DUE

• Different reaction times by study area

• Reconciliation of field observed turning movements and driver behavior

• Local look-ahead distance adjustments

• Development of initial and dynamic cost functions by vehicle type

• Varying values for toll, distance, and capacity attractiveness coefficients in the cost functions

• Coded parking schedules, cleaning schedules, banned turns, bus lane assignments, reversible lanes

• Pedestrian effects using dedicated model in key and approximate methods in other areas

Focus Area

MIDTOWN MANHATTAN

MTM Model Network

Midtown Micro Model Area

34th Street Select Bus Service

& Transit Signal Priority

Study Area

• Midtown Manhattan River-to-river street grid,

Queens Midtown and Lincoln tunnels

Study Objectives

• Transit & Mobility Improve crosstown surface

transit, signal optimization and coordinated TSP

plan, and traveler and pedestrian safety

• Economic Vitality & Sustainability Support

businesses and future growth by improving curb

access and utilization; environmental review

Study Approach

• Analysis Consider local and regional (tunnel-to-

tunnel) trips on 34th Street and surrounding

grid; identify corridor-wide signal optimization

and TSP options

• Outreach Close coordination with MTA/NYCT

and PANYNJ; develop consensus between

community leaders and businesses

Ongoing Opportunities

• Improve integration of transit operations with

signal operations and MIM

• Improve tunnel-to-tunnel travel through real-

time information of crosstown routes

• Safety & Sustainability Improve accessibility for

neighborhoods, parks and waterfront adjacent

to the expressway; slow traffic on local streets

and shift trucks to expressways

• Goods Movement & Economic Vitality Improve

connectivity for trucks on expressways to Hunts

Point, maintaining and promoting economic

vitality

Study Approach

• Analysis Leverage extensive datasets to develop

a regional tool to evaluate proposals

• Outreach Develop consensus between

community leaders, business representatives

and agency stakeholders

Ongoing Opportunities

• Improve mobility & reliability for the I-95 and I-

278 corridors

• Improve traveler decision support with real-time

travel times, route alternatives, time-sensitive

closures

MODELING PLATFORM SUMMARY

• The Platform exists and is actively being used for operations,

planning and MPT work

• NYCDOT is committed to having it as a living tool, regularly

used

• Related concepts will evolve, and the tool can handle new

rules/algorithms, data, and reports

• State and Federal agencies have been involved in a number of

initiatives and studies in NYC, and we see this Platform as

added common ground
