introduction
Introduction
  • The South Broadway Business Improvement District (BID) retained the services of Leonetti Associates to review the traffic and parking conditions along the South Broadway corridor from Caryl Avenue (southern end) to Park Hill Avenue (northern terminus).
  • This report examines corridor-specific issues, identifies transportation systems management techniques and traffic calming measures to balance the efficient movement of traffic and enhance pedestrian safety.
  • Recommendations are made to calm traffic & improve parking along the corridor. The implementation of these measures will create a more friendly, inviting environment to maintain livability, and enhance the economic viability of the South Broadway BID.

Leonetti Associates

methodology evaluation tools
Methodology / Evaluation Tools
  • Traffic Composition - Evaluate the composition of traffic
  • Pedestrian/Vehicle Conflicts - Observe conflicts between traffic and pedestrian movements.
  • Traffic Flow – Operating Level of Service
  • Parking - Availability/Occupancy

“The sum of these factors enhance a business districts economic viability.”

Leonetti Associates

data collection efforts
Data Collection Efforts
  • Traffic Control Devices (Traffic Signals, Signs, Pavement Markings, etc.)
  • Field Investigations – Identified “hot spots” that cause traffic congestion & conflicts
  • Examine On-street/Off-street parking conditions

Leonetti Associates

traffic systems management tsm
Traffic Systems Management (TSM)

TSM – Low Capital Intensive Alternatives that include:

  • Construction of turning bays to improve traffic flow
  • Traffic signal timing modifications to improve traffic flow and reduce queuing through the corridor
  • Parking regulation modifications during peak periods to provide additional travel lanes during traffic periods.
  • Implementation of Speed/Radar Detection to reduce speed
  • Implementation of Red Light Camera

Leonetti Associates

tsm traffic calming techniques
TSM/Traffic Calming Techniques

“Traffic calming is a concept that seeks a more harmonious relationship between vehicular traffic and people.” These techniques are used to enhance livability. Typical calming measures include:

  • Signage/Striping/Enforcement Measures (Non-Physical)
  • Narrowing Measures
  • Horizontal Deflection Measures
  • Vertical Deflection Measures
  • Diversion Devices

Leonetti Associates

signage striping enforcement measures
Signage/Striping/Enforcement Measures
  • Traffic Signage (street names, warning signs, etc.)
  • Crosswalks – identify the safest place to cross
  • Parking Modifications – Parking areas may be adjusted to improve visibility or narrow lanes widths
  • Targeted Police & Parking Enforcement - Enforce all aspects of applicable codes

Leonetti Associates

narrowing measures
Narrowing Measures
  • Bulb Outs – Widening sidewalks.
  • Chokers – Installed mid-block that narrow the street width.
  • Entry Islands – Small islands in the middle of the street that narrow vehicle travel lanes.

Leonetti Associates

horizontal vertical deflection measures
Horizontal/Vertical Deflection Measures
  • Raised Crosswalks – Channelize pedestrian movements and make crosswalks more visible
  • Chicanes – Alternating curb extensions at regular intervals used to narrow the traveled way
  • Striped/Raised Islands – Used to

separate opposing lanes of traffic or

channel vehicles at intersections

  • Speed Bumps/Humps – Used to slow

traffic (Not recommended for major

thoroughfares)

Leonetti Associates

diversion devices
Diversion Devices
  • Diverters – Direct traffic flow at intersections
  • One-Way/Two-Way Operations – Change the directional flow of streets
  • Street Closures – Partial or full closure of a street to divert traffic flow

Leonetti Associates

effectiveness of traffic calming
Effectiveness of Traffic Calming
  • Vehicle Composition/Speed Reduction – Minimize the impact of commercial traffic and reduce vehicle speeds by narrowing the traveled way
  • Accident Reduction – Minimize traffic conflicts
  • Noise Reduction – Reduced commercial traffic volume Air Pollution – The efficient flow of traffic will allow motorists to proceed smoothly reducing queuing

Leonetti Associates

observations and findings
Observations and Findings

Traffic Composition:

  • Broadway is used as a thoroughfare / arterial street
  • The majority of commercial traffic on the corridor is not destined for Broadway
  • Traffic flow, pedestrian safety and damage to the infrastructure is adversely impacted by commercial traffic

Leonetti Associates

observations and findings1
Observations and Findings

Pedestrian/Vehicle Conflicts:

  • Street geometries are not conducive to large turning vehicles
  • Recent streetscape improvements are effective in channeling and demarking traffic lanes/crosswalks
  • Pedestrian street crossing patterns occur along the corridor at mid-block points not serviced by intersections

Leonetti Associates

observations and findings2
Observations and Findings

Traffic Flow:

  • Traffic signal timing plans effectively and safely control traffic during off-peak conditions
  • Traffic is impeded by frictional factors during both the peak & off-peak periods due to turning movements from driveways, side street movements, and loading/unloading activities, etc
  • Traffic flow operates at a higher Level of Service between Caryl Avenue and Valentine lane; and Highland Avenue to Park Hill Avenue
  • Traffic speeds are diminished between Valentine Lane and Highland Avenue

Leonetti Associates

observations and findings3
Observations and Findings

Parking:

  • Parking areas are well defined and traffic signs clearly indicate restricted areas
  • On-street parking is at a premium between Valentine Lane and New Main Street
  • Off-street parking lots are highly occupied at each facility along the corridor
  • The two-hour metered parking limit is not being effectively enforced

Leonetti Associates

Leonetti Associates

summary
Summary
  • The implementation of Transportation System Management techniques combined with proven Traffic Calming measures will create a more friendly, inviting environment for residents and shoppers
  • The recommendations offered are basically low-cost, proven engineering concepts that can be installed immediately, and do contain hefty operational/maintenance requirements
  • The efficacy of these treatments can be measured through a pilot program monitored by Yonkers governmental agencies and representatives of the South Broadway BID
  • The most significant benefits of the treatments described herein will be achieved when a comprehensive, integrated set of actions are implemented, including enforcement
  • A pilot program can be instituted to measure the benefits of selected alternatives
