Lesson 7 Flashcards
the use of physical devices, streetscaping treatments and other measures (including regulations and other non-physical measures) to influence vehicle operation, in order to create safer and more livable local streets
Local Area Traffic Management (LATM)
the objectives of LATM is to support a transport system which is _____, ______, ______, and ______
convenient, safe, equitable and sustainable
The objectives of LATM is to support a transport system which can be achieved by
- Improving the pedestrian environment and linkages
- Improving opportunities for cycling
- Minimize freight impact by directing trucks onto efficient arterial routes away from residential areas
- Reduce dependencies on private vehicles over time with better travel choices.
a continuous, unobstructed, reasonably direct route between two points that is intended and suitable for pedestrian use. Pedestrian facilities include but are not limited to sidewalks, walkways, accessways, stairways and pedestrian bridges.
Pedestrian Facility
average walking speed, expressed in ft/sec
Speed
number of pedestrians passing a point per unit time, expressed as pedestrian/minute or pedestrians/15 minutes.
Pedestrian Flow Rate
refers to a perpendicular line of sight across the width of a walkway.
Point
pedestrians per minute per foot
Unit Width Flow
a number of pedestrians walking together in a group, usually involuntarily
Platoon
average number of pedestrians per unit area within a walkway or queueing area, expressed in pedestrians per square foot
Pedestrian Density
average area provided for each pedestrian, which is the inverse of density, expressed in square feet per pedestrian.
Pedestrian Space
minimum area requirement of a person when standing.
Body ellipse
measure of body ellipse
18 in by 24 in.
This minimum space requirement of ______ is not sufficient if human beings are carrying luggage or backpacks.
2.3 ft²/person
Pedestrian Speed-Density-Flow Relationship
v = S x D
Average Pedestrian Flow formula
v = V/15We
The width of walkway that can effectively be used by pedestrians
clear walkway width
Environmental Factors considered in designing pedestrian facilities
Comfort
Convenience
Safety
Security
Economy
defined as a vehicle having two tandem wheels propelled solely by human power on which any person or persons may ride.
Bicycle
a trail, path or part of a highway or shoulder, sidewalk or any other means specifically marked and assigned for bicycle use.
Bikeway
Classification of Bikeway
Class I bikeway
Class II bikeway
Class III bikeway
completely separated from vehicular traffic and within an independent right-of-way or the right-of-way of another facility. Bikeways separated from vehicles but shared by both bicycles and pedestrians are included in this classification.
Class I bikeway
part of the roadway or shoulder is marked by pavement markings or barriers. Vehicle parking, crossing or turning movements are permitted within the bikeway
Class II bikeway
shares right-of-way with motor vehicles. There is hardly any protection from motor vehicles, although the signing helps to make the motorists aware of the presence of bicyclists
Class III bikeway
