EDD-2290-C02 – Civil Design & Drafting – Warren Salberg – 2018-04-04

INTRODUCTION

EQUITABLE USE

Crosswalks downtown

• Audible signals for vision-impaired people
• Visual signals for sighted people
• Drop-curb design for wheelchair access &

limited tripping hazard

• Tactile paving allows for prevention of

slippage Bicycle route, London Rd.

• Low traffic density; offers no calming effect
• Not at offset road
• Low-visibility bollards may offer night-time

hazard

• Diverts drivers away from destination,

creating longer routes

FLEXIBILITY IN USE

Chinook Tourism, Scenic Dr. & Mayor Magrath Dr. S.

• Design offers access to those without

mobility challenges.

• The sloped ramp is easy for people in wheel

chairs and those with other impairments.

Recycle, garbage bin, Henderson Park

• Angle offers accessibility to wheelchair

users but falls short.

• lid is too high to reach
• lid is too heavy
• offers recycling bin for bottle collectors

but contains garbage – intended design missed its mark.

SIMPLE & INTUITIVE USE

Active Park, Scenic Dr. S.

• Simple instructions, simple design,

simple to use

• Provides high benefit per effort

Traffic circle – 4 St. & 7 Ave. S.

• Low traffic area, unnecessary
• Annoying hindrance of traffic flow
• Waste of civic financial resources

PERCEPTIBLE INFORMATION

Automated washroom downtown

• Without reading one can easily

understand the diagram.

• Both French and English instruction.
• Instruction are bulleted.

Chinook Tourism, 28 St. & Scenic Dr.

• S. intersection
• Left lane turns left; right lane goes

straight and turns right

• Perception: no through route, road ends
• No direction arrows on pavement (show

yellow)

TOLERANCE FOR ERROR

HONK Park & Pay service

• Elimination of manual Zone input

allows for less error in zoning

• Automated GPS location

Automated washroom downtown

• Its location is close to a bar
• Social demographics in the area have

led to continued misuse of the washroom

LOW PHYSICAL EFFORT

Emergency callbox at University of Lethbridge

• Very distinct color and text
• To contact security there is a big red button
• Flashing light on the top of pole for reduced

response time. 28 Ave. S. at Parkbridge Estates

• Inadequate Drainage, and low slope
• Entire sidewalk freeze over with ice in

melting season

• This is in front of an elderly gated

community

SIZE AND SPACE FOR APPROACH AND USE

Table at Galt Garden

• Wide wheelchair access allows good

turning radius

• Cement pad allows for walking behind

seating

• Approachable from all directions

Entrance at Sport Chek

• When door is open, wheel chair access is

limited forcing you into the street.

• Walkway is awkwardly sloped

downwards from the door to the street

• Bollards reduce sidewalk area for all

pedestrians.
