This document summarizes research on modeling pedestrian behavior in New York City. It discusses:
- When pedestrian modeling is needed, such as for environmental assessments or safety projects where pedestrian volumes will increase.
- Key findings from Phase 1 of the research, including developing a methodology to estimate pedestrian saturation flow rates based on NYC conditions. Field observations were made at a Manhattan intersection to study factors like pedestrian speeds and reaction times.
- Next steps involve using new technologies to further study pedestrian behavior and revisiting modeling methodologies to better reflect conditions in high-density NYC areas.

Pedestrian level of service for crosswalks at urban intersectionsTHOTA AKHIL
Pedestrians form the largest road user group.
As walking is the primary means of human locomotion, they are the most unguarded road users at intersections.
Pedestrians are allowed to pass only on the crosswalks, walkways which are provided for them.
In urban centers, pedestrian flows can be significant, they must be accommodated in planning & design of traffic facilities and controls.
Most of the potential pedestrian conflicts exist at the intersections.

Our project is the complete study about both Spot speed studies and Speed delay time survey. This topic is a part of Transportation Engineering. This report helps you to understand this topic in detail. This report will also help you to make project on associated topics in traffic engineering. In spot speed, We discussed regarding various methods available to perform the test, Our team practically performed test and established a speed limit zone near a school. Coming to speed delay time survey, we conducted a survey at a selected stretch and came out with solutions to the problems faced by the vehicle users using that stretch.
Talk given at the kick-off of the ERC MAGnUM PhD week on the ALLEGRO program. The talk gives both an overview of ALLEGRO and then focusses more on active mode traffic operations.

9. Environmental Assessments (EAs)
• Model anticipated future capacities and Levels of
Service (LOS) at key pedestrian elements where
project-generated pedestrian volumes would be added
Safety Improvement Projects
• Model existing and future conditions at locations
where safety improvements are being made that would
affect pedestrian capacity and LOS

12. New York City Pedestrian Modeling Methodology
The 2014 City Environmental Quality Review (CEQR)
Technical Manual includes an LOS analysis based
on HCM 2000 and HCM 2010.
We analyze:
• Sidewalks
• Corners
• Crosswalks
21. Phase 1: Project Goals & Objectives
Goal
• Verify HCM pedestrian LOS crosswalk methodology for
high-density NYC conditions
Objectives
• Develop a methodology for estimating the pedestrian
saturation flow rate based on NYC conditions
• Assess distribution of pedestrians speeds along the
travel path in the crosswalk
• Estimate pedestrian saturation flow rate and crosswalk
capacity
• Determine LOS
22. Phase 1: Concept of SFR For Pedestrian Crosswalks
Concept: Develop a base saturation flow rate for
pedestrians
Where:
• 𝑺 𝒑: 𝑷𝒆𝒅𝒆𝒔𝒕𝒓𝒊𝒂𝒏 𝑺𝒂𝒕𝒖𝒓𝒂𝒕𝒊𝒐𝒏 𝑭𝒍𝒐𝒘 𝑹𝒂𝒕𝒆
(ped/ft of width per minute of effective WALK time)
• 𝑺 𝒑 𝟎
: 𝑰𝒅𝒆𝒂𝒍 𝑷𝒆𝒅𝒆𝒔𝒕𝒓𝒊𝒂𝒏 𝑺𝒂𝒕𝒖𝒓𝒂𝒕𝒊𝒐𝒏 𝑭𝒍𝒐𝒘 𝑹𝒂𝒕𝒆
(ped/ft of width per minute of effective WALK time)
• 𝒇𝒊: 𝑨𝒅𝒋𝒖𝒔𝒕𝒎𝒆𝒏𝒕 𝑭𝒂𝒄𝒕𝒐𝒓𝒔 𝒕𝒐 𝒂𝒄𝒄𝒐𝒖𝒏𝒕 𝒇𝒐𝒓 𝒏𝒐𝒏-𝒊𝒅𝒆𝒂𝒍 𝒄𝒂𝒔𝒆𝒔
23. Phase 1: Factors Affecting SFR
Determine the significance of:
• Area/pedestrian type (CBD, age/gender, commuters)
• Conflicting turning vehicles
• Opposing pedestrian flow (impedance)
• Pedestrian arrival during a cycle (%WK,%FDW,%DW)
• Distracted pedestrians
• Crosswalk blockage (by encroaching vehicles)
• Platooning and crowding
• Corner pedestrian density
• Pedestrians with bags/luggage/strollers
24. Phase 1: Estimating Pedestrian Crosswalk Capacity
Similar to roadway capacity calculations for lane group, once
the pedestrian saturation flow rate is estimated, we can
theoretically determine the pedestrian facility’s capacity,
which can then be compared with flows to determine LOS.
