MEMORIAL DRIVE

Road Diet

The Route 9 Corridor Master Plan

• Identifjes the reinvestment and redevelopment strategies for the Route 9 Corridor

south of Wilmington, Delaware

• Plan recommended a road diet along Memorial Drive

What is a Road Diet? Convert a two-lane roadway to a single lane in each direction. Maintain on-street parking and add bike lanes.

Considerations for Road Diet

• Crash History
• Traffjc Volumes
• Transit Stop Locations
• On-Street Parking
• Pedestrian Crossing Distances
• Turn Lane Feasibility
• Utility Pole Locations
• Center Median
• FHWA Road Diet Informational Guide

FHWA advises roadways with ADT of 20,000 vehicles per day or less may be good candidates for a Road Diet

Project Background

• Project area approximately 1 mile in length
• Bordered by two signalized intersections, Delaware Route 9 and US Route 13
• Five unsignalized intersections exist
• Karlyn Drive (West)
• Parma Avenue
• Karlyn Drive (East)
• Bizarre Drive
• Lind Avenue

MEMORIAL DRIVE

Existing Conditions

Existing Conditions:

• 9,000 AADT (Annual Average Daily Traffjc)
• DART Bus Route 14 traverses along the roadway and

has stops at each unsignalized intersection

• Driveways to single family homes, on-street parking,

and sidewalks exist along both sides of the roadway

• Bike lanes do not exist
• Pedestrian crossings along Memorial Drive are provided

at the Bizarre Drive and Karlyn Drive (East) intersections

• Crash data from April 2015 to April 2018 reported a

total of 37 crashes

• 20 of the crashes were angle incidents
• 1 crash involved a pedestrian crossing Memorial Drive

between the Parma Avenue and Karlyn Drive (East) intersections

Proposed Conditions

Proposed Conditions:

• Pedestrian crossings will be provided at each

unsignalized intersection

• Bicycle lanes will be provided along both sides of

roadway

• On-street parking will be maintained
• Feasibility of adding turn lanes will be determined at

each unsignalized intersection

• Transit stops will be maintained

Results

Benefjts of Road Diet

• Slower speeds
• Confmict point reduction
• Added bike facilities which provide a

connection to the statewide bicycle route along Route 9

• Installation of bike facilities encourages

FHWA’s Every Day Counts (EDC) program that supports connected multimodal transportation networks, and promotes DelDOT’s Complete Streets Policy

• Shorter pedestrian crossing distances
• No changes to traffjc operations at

adjacent signalized intersections

• Consistent with Route 9 Corridor

Master Plan

Anticipated Construction Fiscal Year 2020/2021

Updated timeframe information will be provided via the DelDOT.gov project website

Traffjc Analysis

• Results same with or without road diet
• Signalized intersections would continue to
• perate with delays of approximately 30

seconds or less per vehicle

• Minor street approaches at unsignalized

intersections would continue to operate with delays of approximately 20 seconds or less per vehicle

• Left-turning movements along Memorial

Drive at the unsignalized intersections would continue to operate with delays of less than 10 seconds per vehicle
