SUSTAINABLE TRANSPORTATION: LESSONS FROM MARS
![Page 2: Dr . Ari K. Jónsson](https://reader033.vdocument.in/reader033/viewer/2022061617/5681637d550346895dd45dbc/html5/thumbnails/2.jpg)
Towards Sustainable Mobility• Balance is key
– Available energy– Use of energy
• Renewable energy– Lower production– Sometimes irregular
• Energy usage– Driven by behavior– Systems play a role

Motivating Example: Mars• Limited energy production
– But renewable• Cyclical and irregular power
– Solar panels• Systems operations critical
– Utilize energy well• Behavior is dominating
– Operate within budget– Achieve all objectives

So, what is the problem?• Scientist objectives
– Gather data– Move rover
• Energy limits– Battery status– Sunlight forecast
• Outcome– Plan for rover– Happy scientists

Software part of solution

Lessons for Sustainable Mobility• Can be sustainable when you have to be
– Power production– Power usage
• Software and systems play a key role– Achieve more with less– Support changed behavior
• Application to energy and mobility– What changes when applied to humans
• Some steps in that direction
![Page 8: Dr . Ari K. Jónsson](https://reader033.vdocument.in/reader033/viewer/2022061617/5681637d550346895dd45dbc/html5/thumbnails/8.jpg)
Interdisciplinary Approach• Not focus only on hardware and social
– Software and behavior are keys• System must change behavior
– Example: Electric car rental at RU– Engineering developed car– CS developed reservation systems– Management set up access and incentives
• Looks promising

Final words• Sustainability always theoretically possible
– But, often requires impossible changes• Need to balance desire and cost
– Increase level of sustainability– Improve behavior to match supply
• Technology can help– Assist humans in achieving goals sensibly– Operate systems as effectively as possible– Combine the two – move one step closer
