§  Number of reported conflicts among users.
§  Facility management to minimize user conflicts.

Topography
Presence of steep inclines.
§  Portion of sidewalks and paths with steep inclines.

Sense of Security
Perceived threats of accidents, assault, theft or abuse.
§  Reported security incidents.
§  Quality of visibility and lighting.

Wayfinding
Guidance for navigating within the station and to nearby destinations.
§  Availability and quality of signs, maps and visitor information services.

Weather protection
User protected from sun and rain.
§  Presence of shade trees and awnings.

Cleanliness
Cleanliness of facilities and nearby areas.
§  Litter, particularly potentially dangerous objects.
§  Graffiti on facilities and nearby areas.
§  Effectiveness of sidewalk and path cleaning programs.

Attractiveness
The attractiveness of the facility, nearby areas and destinations.
§  Quality of facility design.
§  Quality of nearby buildings and landscaping.
§  Area Livability (environmental and social quality of an area).
§  Community cohesion (quantity and quality of positive interactions among people in an area).

Factors Affecting Accessibility

Name
Description
Current Consideration
Transport Demand
The amount of mobility and access that people and businesses would choose under various conditions (times, prices, levels of service, etc).
Motorized travel demand is well studied, but nonmotorized demand is not. Travel demand is often considered exogenous rather than affected by planning decisions.
Mobility
The distance and speed of travel, including personal mobility (measured as person-miles) and vehicle mobility (measured as vehicle-miles).
Conventional transport planning primarily evaluates mobility, particularly vehicle mobility.
Transportation Options
The quantity and quality of access options, including walking, cycling, ridesharing, transit, taxi, delivery services, and telecommunications. Qualitative factors include availability, speed, frequency, convenience, comfort, safety, price and prestige.
Motor vehicle options and quality are usually considered, using indicators such as roadway level-of-service, but other modes lack such indicators and some important service quality factors are often overlooked.
User information
The quality (convenience and reliability) of information available to users on their mobility and accessibility options.
Frequently considered when dealing with a particular mode or location, but often not comprehensive.
Integration
The degree of integration among transport system links and modes, including terminals and parking facilities.
Automobile transport is generally well integrated, but connections between other modes are often poorly evaluated.
Affordability
The cost to users of transport and location options relative to incomes.
Automobile operating costs and transit fares are usually considered.
Mobility Substitutes
The quality of telecommunications and delivery services that substitute for physical travel.
Not usually considered in transport planning.
Land Use Factors
Degree that factors such as land use density and mix affect accessibility.
Considered in land use planning, but less in transport planning.
Transport Network Connectivity
The density of connections between roads and paths, and therefore the directness by which people can travel between destinations.
Conventional planning seldom considers the effects of roadway connectivity on accessibility.
Roadway Design and Management
How road design and management practices affect vehicle traffic, mobility and accessibility.
Some factors are generally considered, but others are not.
Prioritization
Various strategies that increase transport system efficiency.
Often overlooked or undervalued in conventional planning.
Inaccessibility
The value of inaccessibility and external costs of increased mobility.
Not generally considered in transport planning.
