3. Introduction
• Charles Helou bus station is a construction on the
northern side of Beirut city centre, along the harbor and
under the major highway running to the north. It used to
serve as a hub that connects Beirut with cities in North
Lebanon and Syria
Gemmayze is a residential area and is the destination for
all those wishing to spend their night out. Its main street
is dealing with lots of serious problems that make its
situation worse especially during the weekends. Besides
the annoying noise and traffic issues, visitors suffer from
valet-parking related problems
4. Problems Statement
Problem Solution
In-appropriate design of Charles Helou
Station
New facility design
Duration spent searching for a parking
space in Gemmayze.
Unavailability of sufficient parking spaces
Wastes such as inflated waiting times
A new park-and ride system
High number of cars when compared to
the capacity of the street.
Air Pollution
Noise
Scheduling of a bus system that serves the
clubbers of Gemmayze
5. Data Collection
• Site visit to Charles Helou Station
- Surface area
- Current entrances/exit
- Current ramps
• Interviews
a. Interviewed Mr. Wissam El Haber, owner of VIP parking control
- How many parking spaces do they have?
- What is the approximate waiting time of the passenger to get his car back?
b. Interviewed restaurants and pubs managers
- Do they offer valet service?
- When is the peak day/time?
c. Interviewed Gemmayze residents and visitors
- What are their complaints?
6. Data Collection
• Data collection points on Gouraud Street:
3 entrances
3 exits
• Data was collected with an interval of 10mins during peak hours
• Divided the Street into zones, with respect to the entrances/exits

10. Main Objective
• Compare the time spent before finding a parking space to in Gemmayze to the
total time of our proposed park-and-ride system

Gemmayze (Traffic Delay and
insufficient spaces)

12. Assumptions
•8:00 pm to 1:00 am is the peak period, thus this period is the one to be simulated.
•Flow of cars is the same on the 2 entrances .Cars will have 2 parking options: either on the 1st or the 2nd floor with 50%
chance each.
•There are enough parking spaces to accommodate for all clubbers’ cars.
•The cars move at a speed of 20 Km/hr inside the parking lot.
•No delay of parking is due to the bus rotation.
13. Facility Related Decision
1 entrance for each floor
Communication
between floors occurs
via ramps
Each floor constitutes of
8 zones
1-way traffic
Charles
Helou Station
17. Transportation Model
• How to pick the appropriate bus capacity?
Maximum number of visitors per hour is around 100 passengers
• Cannot accommodate this high capacity
Require larger parking spaces
Higher capital and operating costs
Complications with existing system infrastructure: narrow streets of Gemmayze
• Hyundai County
Seating capacity: 25
Minimum turning radius: 6.2 m
18. Sequential Model
• One Route connecting the 4 stops
• Passengers wait in a queue at each pick up point, until the bus arrives
• Buses are ‘created’ based on schedule
• Passengers depart from the drop off point to their destination
• Total route time is estimated at 15 min
19. Sequential Model
• Number of buses is incremented, by updating the schedule
• Average waiting time and its maximum value are generated
Sequential route
Number of buses Average Waiting time/ Maximum waiting time
2 (scheduled every 8min) 9.16/ 19.79
4 (scheduled every 4min) 4.17/ 14.88
5 (scheduled every 3min) 1.18/ 3.5
20. Dedicated Model
• Each stop in Gemmayze has its own route
• Same model as sequential, but 4 entities were created for buses
• Each one is incremented
21. Choosing the optimal model
1 • Choose the optimal number of buses in the sequential model
2
• Choose the optimal number of buses in the dedicated model
3
• Do a cost effectiveness analysis
4
• Pick the best one
22. Choosing the optimal model
• 1st constraint: average waiting time
How much time are people willing to wait at the bus stop
Based on people’s answers: 5.1 minutes

23. Choosing the optimal Model
8:00 8:05 8:10
• 2nd constraint: Maximum waiting time
Assume a bus leaves CHBS every 5 minutes
Maximum Value of the waiting time (Arena) < 10 minutes
Passenger should not miss the bus more than once (due to capacity limit)
24. Choosing the optimal model
Number of buses Average : Max
Sequential Based on schedule 2 9.16 : 19.79
4 4.17 : 14.88
5 1.18 : 3.5

2 3.94 : 4.82
3 1.21 : 3.4
Stop4 1 3.12 : 5.4
2 1.57 : 2.92
• For the sequential : 5 buses
• For the dedicated: 7 buses
26. Cost effectiveness analysis
• Fixed Cost ●Variable Cost
Vehicle Purchase: A = 55,000* (A/P, 10%, 12) = 8,074$/year √ Fuel Cost/year =
52weeks*3days/week* number of trips/day*number of km/trip*0.12$/km
Insurance: 600$/year
Driver’s Salary: 8,118$/year
• Total cost /year of sequential model with 5 buses = 77,080$
• Total cost/year of dedicated model with 7 buses= 103,148$
Fixed Cost ($) Variable Cost ($) Total Cost ($)
One bus sequential 14,218 1,198 15,416
One bus for Stop1 14,218 730 14,948
One bus for Stop2 14,218 450 14,668
One bus for Stop3 14,218 471 14,689
One bus for Stop4 14,218 320 14,538
27. Cost effectiveness analysis
• Sequential model with 5 buses is the one to be Implemented
• We also made sure that the number of passengers on the bus is not too low.
• The maximum number of passengers waiting will be used to design the waiting
area in Charles Helou Bus Stops
28. Desired Facility Layout
• General Planning
• Parking Angle
• Parking Space Dimensions
• First Floor: 600 paring angle and 3.17 parking stall width
Leads to a total of 310 cars after removing the length of columns and concrete constructions.
• Second Floor: 600 paring angle and 3.17 parking stall width
Leads to a total of 348 after removing the length of columns and concrete constructions.

34. Environmental Aspect (Current)
• We are going to base our emission
study on the European manufactures
emission factor for their cars in 2010
• Specific emissions of CO2 = 130 + a *
(M – M0) where: M is the mass of the
vehicle in kilograms (kg) M0 is 1372
kg is 0.0457
• Based on what we got total of 650
cars accumulated for the 5 hours.
• Each car would have an estimation of
1 km which is the length of
Gemmayze Street, then it would have
a total of 85,150 kg emission of CO2.
35. Environmental Aspect (Desired)
• However, if we enable the bus shuttle which only depends on 5
minibuses at max that has an average 3500 kg then it has an emission of
119 kg/km per bus.
• The distance from CHBS To station at Gemmayze is 1 km and it has a
trip time of 10 min at maximum (Distance+ Drop-off+ Pickup),
• Then to get the distance traveled we multiply the estimated velocity of
bus the time it is tackling which is 5 hours, so we have d= v*t= 50
km/hr*5 hr=250 km as a total distance for all buses
• Multiplied by emission of 119 kg/km per bus =29,750 kg is the total for
the 5 buses put for this scenario.
• So we would witness a reduction by 65% on its air pollution
Current StateCO2 emissions Desired State CO2 emissions

36. Conclusion
• Our proposal will have positive impacts on both the environmental and economical
aspects.
• It will also change the system to raise the quality of living of Gemmayze residents as it
solves Gemmayze’s problems, those related to noise and illegal parking.
• This will hopefully increase the flow into Gemmayze and make this area appeal to
Lebanese and tourists.
