QUESTION ASSIGNMENT 1
A proposed development will be constructed near the Putrajaya-Kajang highway as
shown in Figure 1.
Figure 1
The development consists of an office building with 102,000 square meter floor area and
a 295 units condominium tower.
It is expected will attract 3.3 person-trips per 100 square meter floor area per hour in
the morning, whereas the condominium will produce 1.45 person-trips per unit per
hour. It is estimated that only 16% of the generated trip by the condominium destine to
the office building in the development area.
Mode Split Average
Capacity
Car 55% 1.9
Motorcycle 9% 1.15
Bus 36% 50
You are required to:
a) Compute production and attraction.
b) Compute the number of persons entering and exiting the development area per hour in
the morning.
c) Compute the number of each transport mode entering and exiting the development in
the morning.
d) If 80% of the attraction is from Kajang, determine the minimum width of the bridge.
Proposed Development
To Kajang To Putrajaya
SOLUTION ASSIGNMENT 1
a) Compute production and attraction
Land Use Residential Unit Production rate
(person-trip / unit /
hr)
Morning production
(person-trip / hr)
Condominium 295 1.45 428
Land Use Residential Unit (m2) Attraction rate
(person-trip / m2 /
hr)
Morning Attraction
(person-trip / hr)
Office building (102000/100) = 1020 3.3 3366
b) Compute the number of persons entering and exiting the development area per hour in
the morning
Land Use Number of person
from the
condominium
destine to the office
building in the
development area
(person-trip / hr)
Number of persons
entering the
development area
(person-trip / hr)
Number of persons
exiting the
development area
(person-trip / hr)
Development area (16/100) x 428 = 68 3366 – 68 = 3298 428 – 68 = 360
c) Compute the number of each transport mode entering and exiting the development in
the morning
Number of each vehicle entering development:
Land Use Entering Modal Split Person Trip Number of vehicles
car motorcycle bus car motorcycle bus car motorcycle bus

3298 55% 9% 36% 1814 297 1187 955 258 24
TOTAL 955 258 24
Number of each vehicle exiting development:
Land Use Exiting Modal Split Person Trip Number of vehicles
car motorcycle bus car motorcycle bus car motorcycle bus
Development

360 55% 9% 36% 198 32 130 104 28 3
TOTAL 955 258 24
D) If 80% of the attraction is from Kajang, determine the minimum width of the bridge.
Land Use Attraction from kajang (person-trip / hr)
Development area (80/100) x 3298 = 2638
Numbers Quantity
Cars 2638/1.9 = 1388
Lane *For Malaysian Standard: 1800 Cars Per Link
1388/1800 = 0.77 ≈ 1
Items Description
Bridge Width *assume 1 lane is 3.5m, road shoulder is 1m, marginal strip is 0.5m.
Therefore, bridge width for two lane is:
= (3.5m + 1m + 0.5m) x 2
= 10m
