The main facilities needed for pedestrian movement are pathways
that are usually separated by curbs from motorized traffic. Accessibility is
the ease of which people can obtain their desired needs and services with
little and comfortable physical effort. For walkability, the term accessibility
refers to ‘Accessible Design’ which means that facilities are designed to
accommodate people of different abilities and needs.  

 

 

 

 

 

 

In an article by Queensland Transport (2005), it was explained that
pedestrian facilities that are designed for disabled people will also support
to the needs of other pedestrians, for example, parents using children’s
trolleys. People with disabilities and those without private vehicles mainly
have a smaller amount of access to many activities in the community and thus
make significantly fewer trips, especially in a car-dominated community.

An essential design element that is crucial to
accessibility is the curb zone. The curb zone is the primary barrier preventing
vehicles and other external elements such as water from invading the sidewalk
space. It indicates where the vehicle area ends and where the pedestrian area
begins.

 

The ADA (Americans with Disabilities Act) has developed
design guidelines for pedestrian accessibility into buildings and facilities
along with the public right-of-way. These guidelines are named the ADA
Accessibility Guidelines (ADAAG). These guidelines cover the aspects related to
access to paths, roads, and facilities with applications to construction and
alterations.

Curb extensions and ramps are essential design elements
required for appropriate pedestrian accessibility in the road network. Curb
extensions increase the range of the sidewalk towards the vehicular travel
lanes which reduces the street width but also improve the pedestrian crossing
and access by helping motorists and pedestrians see each other and reduce the
time that the pedestrians spend in the street. Vehicles are forced to slow down
and turn at slower speeds and prevents parking of vehicles close to
intersections. Curb extensions also provide spaces for curb ramps to be placed.
Curb Ramps enable walking pedestrians as well as others (Cyclists, Wheelchair
users) to move between streets and sidewalks. Figure (X) contains an image
showing the placement of curb ramps on the sidewalk curb extension for proper
accessibility of different pedestrians, wheelchair user, and cyclists from the
street zone into the pedestrian zone.
