Lecture 17 Flashcards
Who are the stakeholders in parking
#Drivers #Businesses #Developers #urban residents #Pedestrians
How is parking demand divided
# If it is at trip origin then it is for residence # if it is at trip destination then it is for work, business, shopping....
How is parking supplied
# On street through curbside # Off street through parking lots and parking garages
On street parking is convenient for whom
Curb side parking is convenient for people running errands (short trips) and for goods delivery
True or false
Curb space is a valuable resource and privilege that needs to be restricted especially in CBD (central business district)
True
Prohibition o on-street parking to maintain road way capacity is necessary because streets should favor vehicle movement over vehicle storage
true
Off - street parking
#Surface parking : desirable where land is less expensive # parking garages: underground or above ground, appropriate where land is expensive
Parking by duration
#Short term parking (<1/2 hrs like loading-unloading trucks) #Shopper parking (<2 hrs) #long term parking (employee or residential , should not use curbside)
Acceptable walking distance when parking for long term users versus short term users
long term users will generally accept longer walking distance than short term users as customers or visitors
parking area types
Off street parking is the most common and accepted method facility parking needs
on street
True
In off street parking we must ensure at least 15 meters distance is provided from proposed area parking entrances and the exists to intersections
true see page 36
In on street parking area type
See page 38
favor parallel parking
# Maintain a minimum distance of 15 meters from on-street
parking spaces to intersections and off-street parking area
entrances
# ensure street maintain required traffic capacity
#– Break up long lines of vehicles with occasional planting

Parking configurations
See pic 43
#Parallel configuration # Perpendicular configuration #Angled (30,45,60 degrees) to the driving lane (one way operation)
As a general rule of thumb , the closer to perpendicular parking configuration, the more vehicles that can be parked per linear meter. Thus the area required by each parking configuration will vary.
True
(72 veh for perpendicular or 90 degrees parking per 100 linear meter versus less than 40 vehicles for 30 degrees parking.)
Name the advantages of parallel parking
#Functional in extremely narrow and linear spaces. # Requires minimum pavement area
Name the disadvantages of parallel parking
# Difficult maneuvers for most drivers # Less visibility of adjacent traffic # Inefficient use of on-street space
Name the advantages of perpendicular parking
#Functional with one way or two way aisles(ممرات) #Most efficient and economical (max veh per linear meter and per squarer meter, effective in low turnover rate )
Name the disadvantages of perpendicular parking
# requires widest area # Difficult maneuvering for some drivers # Two-way traffic can create some visibility problems
Name the advantages of 60 degrees parking
# fast turnover rate # Easy maneuvering in and out of parking spaces # Good visibility # Lends itself to one way aisles
Name the disadvantages of 60 degrees parking
# Requires more pavement per vehicle than perpendicular configuration # handles fewer vehicles per linear meter # Difficulties of inefficient circulation pattern and one-way aisles
Name the advantages of 45 degrees parking
– Reduced width requirements for layout
– Easy maneuvering in and out of parking spaces
– Good visibility to the rear
Name the disadvantages of 45 degrees parking
Doesn’t work well with two-way aisles
– Requires more pavement per vehicle than perpendicular
parking configuration
Name the advantages of 30 degrees parking
– Easy parking
– Reduced width requirements for layout
Name the disadvantages of 30 degrees parking
Requires the most pavement per vehicle
– Doesn’t work well with two-way aisles
