Problems in Public Transportation
2
Transport Inadequacy
During peak hours, there are not enough transportation vehicles available, which results in overcrowded vehicles and discomfort for passengers.
3
Centralization
Most public transportation systems service only areas that have high population density .
These services do not expand outside of the large urban areas.
4
Fares
Most public transportation systems have developed a flat fare payment structure. In many cases, this flat fare actually discourages shorter trips by making longer trips less
expensive .
5
Fixity
Some public transportation systems are fixed, as trains and subways must travel over specific tracks.
A bus route is not fixed, because the driver can change the route by taking different streets; however, a subway route is fixed, as the subway can only travel through the specified subway
tunnels .

UNDERSTANDING WHY SOME PEOPLE DO NOT USE BUSES
7
DRAFT LIST OF BARRIERS:
•Bus stops are too far away •Buses don’t come often enough
•Too long to wait at bus stops •Don’t feel safe waiting at bus stops
•Bus stops are dirty/vandalized •Lack of information/knowledge about times
•Not sure if the bus will arrive on time
8
•Takes too long to get places by bus •Too crowded/too many people on buses
•Fares are too high •Bus drivers are rude/unhelpful
•Buses are dirty/smelly •Need assistance to use bus
•Don’t feel safe on the bus
9
•Have to change buses/get more than one bus
•Need to use car to give other people lifts (e.g. children to school)
•Need car for work

BUS PROBLEMS
11
Delay due to passenger stops
reduced by improvement of the fare collection process, e.g. self-service fare collection (honor
system), greater use of passes, smart cards, etc .
12
13
Pollution Caused By Busses
Buses may contribute to atmospheric and noise pollution in cities .
14
reasons for pollution caused by buses
poor vehicle maintenance, inadequate enforcement of rules and regulations, and inappropriate vehicle type and size.
15
Bus Bunching
In public transport bus bunching refers to a group of two or more transit vehicles along the same route which are scheduled to be evenly spaced, running in the same location at the
same time .
16
17
Explanation of Causes
18
1.Abnormal passenger loads
The time taken for a bus to complete its duties is related to the number of people attempting to
board or alight at stops .
19
20
2.Speed of individual drivers
Another cause is that some drivers are faster than others. This results in catching up on long or high-frequency routes.
21
3.Deliberate acts
bus bunching may be deliberately caused by bus drivers, so that the bus ahead of them picks up more passengers and decreases their own workload.
22
Delay due to right turns
This type of delay occurs when buses are traveling in the curb lane and a queue of right-turning vehicles blocks the bus from moving forward.
overcome by relocating bus stops to the far side of the intersection .
23
Case Example
Right turns may be prohibited as they were on Madison Avenue (with two exclusive bus lanes between 45th and 59th Streets) in New York City, significantly reducing bus travel times. This solution, however, may not be viable everywhere.
24
• Type of another vehicles which can travel in Madison streets with bus
Buses Bicycles Between 44th and 46th Streets, taxis carrying at least one
passenger are permitted to use the lanes to make a right turn onto 46th Street.
Authorized emergency vehicles Traffic / parking control vehicles Snow plows, sand spreaders, sweepers and refuse trucks Highway workers Highway Inspection and Quality Assurance vehicles,
compliance inspection unit and street assessment unit vehicles
25
Delay due to general congestion
This component can be reduced if general congestion is reduced or if buses are given preferential treatment through creation of a reserved lane. (Using the bus priority method)
26
Delay due to traffic signals
Priority treatment of buses at intersections holds the potential to reduce a significant source of delay in bus operations.

28
Creating Better Bus System
29
Bus systems provide a versatile form of public transportation with the flexibility to serve a variety of access needs and an unlimited range
of locations throughout a metropolitan area .
30
Designing accessible buses
Bus vehicles should be designed according to universal design principles and should
be able to easily accommodate a variety of users, including people using mobility
aids and walking aids, people with a vision impairment, including those with guide
dogs, cyclists, parents with prams and strollers, and people travelling with luggage or shopping trolleys.
31
Better bus stops
Bus stops should have good amenities, especially at high-use locations, including
shelter, seating and lighting, as well as being well-maintained.
32
The driver relationship
A good driver places priority on his passengers needs, seeks to facilitate access for
everyone, and is friendly, courteous and well-presented to make passengers feel welcome.
33
Navigating the bus network
Many people lack knowledge of how to use bus systems, including whether they will
be able to use the service, how to plan journeys using the bus network, how to findthe information they need to make bus journeys, and what accessibility features will be available for a given service.
34
Route scheduling and network design
Services should be punctual and frequent, have a wide span of operating hours ,
prevent overcrowding, meet the needs of local communities, make low-floor buses
available, and support interchanging
35
A system that supports bus access
Making decisions about the bus network should incorporate social and environmental objectives.
Good community engagement and feedback mechanisms would improve the
decisions made about accessibility of buses
