4. FAQS ON TRANSPORTATION PLANNING
What is urban
transportation
planning?
Why are
highways so
important?
What is the
future of urban

5. FUNCTIONS OF URBAN TRANSPORTATION
PLANNING
1. To define
transportation
planning
2.To identify highway
system component
3. To forecast traffic
volume after a
certain number of
years
4. To recall the
purpose and process
of construction
planning design
5. To identify the
mode choice
behavior of
commuters

7. TRIP GENERATION & DISTRIBUTION
The relationships between trips generated and the
relevant variables are expressed as mathematical
equations, generally in a linear form.
For example,
the model could take the following form:
Tij = a0 + a1Z1j + a2Z2 j +L+ anZnj
The Gravity Model is as follows
Tij=
GiAjFij
𝑗=1
𝑛 AiFij

8. The function used to
estimate the total utility
provided by a mode option -
Um = bm+ 𝑎𝑗 𝑧 𝑚𝑗+e
Modal split

12. Parking is one of the major
problems that is created by the
increasing road traffic. It is an
impact of transport development.
The availability of less space in
urban areas has increased the
demand for parking space
especially in areas like Central
business district. This affects the
mode choice also. Parking also has
a great economical impact.

13. OBJECTIVE OF PARKING STUDIES
Parking studies are used to evaluate the
facilities available like
• Parking demand-The parking demand varies during
the day and reaches a peak value during heavy
parking demand time
• Parking characteristics – It refers to the practices
prevalent in the area under consideration, mainly
whether the vehicles are parked on street or off street
• Parking space inventory- the area under study is
surveyed and kerb parking and off street parking
facilities are plotted on a map

14. PARKING SYSTEM
• Parallel parking
• 30 parking
• 45 parking
• 60 parking
• Right angle parking
On street parking
• Mechanical car parking
• Multistory car parking
• Roof car parking
• Surface car parking
• Underground parking
Off street parking

15. ACCIDENT STUDIES
The problem of accidents in India is acute due to complex flow pattern
of vehicular traffic along with pedestrians
Objectives of accident studies
• To evaluate existing design,
regulation and control measures
• To study the causes of accident and
suggest corrective treatment
• To support proposed changes in
design in the particular zone
• To carry out ‘before and after’
studies after implementing changes

18. TRAFFIC VOLUME & DENSITY
TRAFFIC VOLUME(Q)
• Number of vehicles
passing a particular
point during unit time.
• Vehicles/hr
• Measured in daily
volumes(ADT/AADT)
or Hourly volumes
TRAFFIC DENSITY(K)
• Number of vehicles
occupying a unit
length of road at any
instant.
• Vehicles/km
• K=
𝑄
𝑉 𝑠
(Vs free mean
speed)

19. TRAFFIC CAPACITY
Traffic volume-actual rate of flow
Traffic capacity- maximum rate of flow
Types of
capacity :
Basic
capacity
Possible
capacity
Practical
capacity

20. Passenger car unit is an
equivalence factor use to
convert the flow of different
vehicle classes into one
standard vehicle known as
passenger car.
Passenger car unit (PCU)

21. FACTOR AFFECTING TRAFFIC CAPACITY
Lane width
Lateral
clearance
Width of
shoulders
Alignment
Presence of
intersections
Road
geometrics

22. SPEED STUDIES
Speed studies are the studies which are carried out to know the
general trends in speeds of different vehicles over a particular route
depending on various factors
Classified into
two groups:
Spot speed
study
Speed and
delay study

23. SPOT SPEED STUDIES
The instantaneous speed of a vehicle at a point or cross section
is known as spot speed
Space mean speed
• Average speed of
vehicles in a certain road
length at any time
Time mean speed
• Average of
instantaneous speeds of
observed vehicles at the
spot
