Transcript of The transporters

A bus that runs on diesel fuel
-Holds up to 17 people
-1.9m wide
All terrain - effective on the roads

A bus that runs on electricity - hybrid
-Holds up to 17 people
-1.9m wide
All terrain - effective on the roads DESIGN DESCRIPTION The design involves purchasing used small to medium sized trucks (4-5 tonne) from Timor Leste, this is a preferable option as buying the base truck in Australia would mean that once the completed vehicle is shipped to Timor Leste, it is unknown whether or not the mechanics will be able to familiarize themselves with the new imported vehicle compared to the trucks that they already maintain.

Importing trucks from Timor Leste will also ensure that the engines are compatible with the diesel fuel, as the fuel in Timor Leste complies with Euro 3 emission standards, while Australia uses Euro 5 and higher, which has a much lower sulfur content than Euro 3 The buses will be implemented as school buses from the town of Codo within the district of Lautem. There will be 4 buses used in total, 2 for Junior high school children and 2 for High school children.

Our buses will be able to be used for a multitude of different purposes although they will primarily remain school buses for children in and around Codo.
Two of our buses will be used to transport 31 children to a junior high school in Lautnem Village, which is about a 26km drive or more amazingly, currently a 3-5 hour walk. This journey will be reduced to a much more comfortable 45minute bus trip.
The other two buses we plan to implement will transport 28 children to Los Palo, for their high school education. This will be a 55km drive, also reducing the 3-5hour walk to a much more reasonable 1 bus trip. USES TRANSPORT IN TIMOR-LESTE Engineering Communication

Daniele Cullura Transportation is an important issue within rural areas. Residents predominantly cannot afford their own vehicle and so public transport use is prevalent. Public transport, however, is not reliable and road infrastructure is in need of maintenance. Children are required to walk long distances to school which often takes in excess of three or four hours. The community members are interested in alternative design solutions to overcome these challenges. PROBLEM DEFINITION DISCUSSION Weaknesses STRENGTHS - The proposed idea meets the design requirements by overcoming the current transport problems with which the residents of Codo are faced with. - Provides greater safety and well-being for the school children
- The proposed bus is suitable for the environment and terrain of Codo as it is built for off road conditions Strengths continued - Final proposal contains the use of a turbo diesel engine which has many benefits such as : 1. Longer lasting engine 2. Less maintenance required 3. Water proof 4. Not many electrical components in the engine are required 5. Higher torque thus more power 6. Less carbon dioxide and carbon monoxide emissions - The buses all require a skilled and experienced driver - Maintenance will be an issue due to the geographical location and socioeconomic status of Codo - Erosion of roads and frequent landslides will be a weakness due to the heavy nature of the bus

-Bus cost of $180,000 AUD per unit will be considered a weakness in a third world country but will be appropriately funded Regulatory and safety considerations According to the decree law No.2 of the democratic republic of Timor-Leste our EWB design has to comply by the following basic laws:
- the project must make maximum contribution to the economic development, promote greater well-being and quality of life to the civilian of Codo
-Fares and tariffs of the school transport system may be determined freely by the carrier enterprises Most importantly, in order to begin the adequate functioning of the school transportation system and to ensure the safety of the school children, all school buses will be equipped with the following equipment in case of emergency:

- First Aid kit
- Fire extinguisher
- Safety belts for all passengers
- Emergency warning road triangle
- Spare tyre
- Fluorescent safety jacket Additional Uses and
Variations Our buses will also have many other uses which can include:
- Transporting villagers for a fee
- Transporting sick people to and from villages
- Transporting food and goods to remote villages
- Emergency response situations There are also many different variations of our bus which could be implemented in the future for vastly different purposes.
- Larger buses of a similar off-road nature could be used for long journeys across the rugged terrain of Timor-Leste. This would finally offer a mode a transport for people over the rough and rugged terrain of the Timor-Leste landscape.
- Smaller buses with similar off-road capabilities would be invaluable resources for Emergency response teams in Timor-Leste. They will offer access to remote areas, while being capable of carrying the require equipment and personnel, as well as arriving in a timely manner. Chosen Design Option Option 1
-Cheapest option due to engine
-Low maintenance therefore cost effective

--Environmental Impact
-Some environmental impact due to CO2 and CO emissions BUT is still not very damaging on environment
-Diesel is sustainable as it burns slower (use less) --Technical Functionality
-All terrain - handle the earth formed roads of Codo
-Uses a Turbo Diesel engine - high torque/waterproof

-Holds up to 17 people (4 buses supplied therefore 68 people)
-Require a minimum of 59 therefore allowing growth
-Service to travel to many areas of Codo OPTION 3
A bus that runs on electricity - hybrid
-Holds up to 21 people
-1.9m wide
-4.8 tonnes
All terrain - effective on the roads

A bus that runs on electricity - hybrid
-Holds up to 37 passengers
-2m wide
-5.1 tonnes
All terrain - effective on the roads Modifications The Trucks will be modified by ‘All Terrain Warriors’, however it is not known if the trucks sourced from Timor Leste have a four wheel drive (4WD) drivetrain, and so if not will be modified an converted to 4WD. The other modifications include:

Passenger cab on the tray of the truck constructed of reinforced fibreglass and aluminium, seats covered in canvas with rubber floors and double glazed sealed windows. Drivetrain upgrades including heavy duty drive shafts, lockable differential on front and rear axless, low range transmission, heavy duty shock absorbers and height adjustable coilovers. Larger mud specific tyres and forged alloy wheels for increased strength and durability
Powertrain upgrades including intake snorkel for submerged induction and installing a turbo intercooled induction setup for more efficient power production from the low power high, torque diesel engine. Conclusion Our design solution for transport within and around Codo in Timor-Leste, specifically for school children are purpose build 4WD Buses which will be able to handle the rough terrain that the children currently face on their walk to school. Our buses will reduce the time spent traveling to school and increase levels of education. With input from the local Timorese people, we will be able to make our design solution sustainable by utilizing suitable trucks and appropriate shelters where they can be housed. NEXT STEPS "Economic opportunities are likely to arise where transportation infrastructures are able to answer mobility need and ensure access to markets and resources" (Rodrigues 2013)

Mobility is one of the most fundamental and important characteristics of economic activity as it satisfies the basic need of going from one location to the other, a need shared by passengers, freight and information” (Rodrigues 2013)

It can be said the economies that have a greater ability to provide mobility to their people are able to provide a greater degree of opportunity to the economy and the people within it.

Our transport solution will be completely reliable and efficient in terms of the community involvement of Codo. Once implemented into the transport system the community will not have to do any new design work on the project to make it run and be effective making the next steps for the community very basic and simple. The community will use the buses to transport the school children of Codo from schools to home and home to school. Evaluation
Costs - Limiting Factor
Environmental Impact - Minimsing the Impact
Technical Functionality - Efficiency and Dependability
Practicality - Flexibility and Scope for Growth

Cost Analysis Due to the nature of the bus and its service, there would be costs involved after its implementation. These costs would be mainly be related to its on-going operation and its maintenance. Although these costs would be initially a burden, the significant rise in quality of life, education of children and future increases in economic ability would be able to offset these costs in the long run. Initial Cost of Truck: Approximately $40 000Initial Cost of Bus Modifications: Approximately $145 000Total Cost of Bus: Approximately $185 000 (each bus)Cost of Shelter: Approximately $25 000 (once)Cost of Maintenance: Approximately $10 000 (per year) (including driver) (each bus)Cost of Training: $5000Initial Start up Cost: $185 000 (x4 buses)$25 000 (shelter)$10 000 (maintenance) (x4 buses)$5000 (driver training)Total:$810 000Annual running costs: Approximately $15 000
