Class 1: Mobility on Demand Systems, September 3

o   Introductions: Your background, your skills, your passions, and why you are taking this class.

Concepts

o   Networked Cities and Real-time sensing

o   Cybernetic Systems, Control Theory, Feedback loops

o   Mobility on Demand Systems

o   Unbalancing – rebalancing

o   Problems of centralized methods of control

o   Driverless automobiles and rebalancing algorithms

o   Goals of course

o   Course Structure & Roadmap

o   Previous versions and projects of this class

Assignment 1

Do the readings and briefly discuss in the course blog 2 of the following topics:

o   In ME++ Mitchell talks about “electronic nervous systems” of intelligent urban environments. Discuss an example of an intelligent urban system you are familiar with and discuss the elements of the feedback loop, how its form of governance works, and who are its stakeholders (goals, decision makers, evaluators, etc.).

o   Compare different models of sharing that exist (or you can think of) in MoD systems (e.g. vehicle sharing, parking sharing, ride sharing, etc.) What operation/control problems do they have? What would the ideal form of sharing be for you and how would its resources be controlled?

o   Read MIT’s report on driverless automobiles (ignore all technical stuff and focus on results). Suppose that in few years we have driverless automobiles that can be used in shared schemes without the need for redistribution. Is this a plausible solution/future for you?

o   Read both articles of DeMaio that illustrate the history, future and challenges of bike sharing. Do you think in the future we will need better centralized control, more self-governance (incentives for users), or a combination of the two?

Prepare a proposal for your mid-term project (don’t worry if it is not detailed). What aspect of NYC Citi Bike system you want to study?

Reading

o   Read chapters 3, 8, 9 from Reinventing the Automobile: Personal Urban Mobility for the 21st Century

o   Read chapters 1, 2, & Epilogue from ME++

o   Briefly skim: Connected Sustainable Cities.

Assignment 2

Create a visualization in Processing (or D3 if you are familiar with) of NYC Citi Bike focus on an aspect of the data that you want to reveal. Suggestions:

o   Go to http://www.citibikenyc.com/system-data, download and visualize a dataset of your choice.

o   Use NYC Citi Bike’s JSON stations live feed (http://www.citibikenyc.com/stations/json) and make a real-time visualization of Citi Bike’s stations’ inventories.

Post your visualizations in the course blog before class next week

o   Agents, breeds, and behaviors

Lab

o   Vensim tutorial

Assignment 3

Expand the provided template model in Vensim (or develop a new one) and discuss the following questions: what factors limit repositioning rate? What is the maximum service rate? What affects unbalancing? What would be the optimal configuration of fleet size, parking size, and trucks? What solutions might improve the situation and what problems would they bring? Discuss your answers in the course blog and prepare to present your model next week in class.

OR:

Develop a new (or expand the provided) Agent-based simulation model of a bike sharing system using NetLogo addressing the same questions as above.

Post your findings in the blog and prepare to discuss them next week

Class 4: Decision-making and Economics of MoD Systems, September 24

Assignment 3 presentations

Concepts

o   Cost of time

o   Cost of trips

o   Cost of Substitutes and opportunity cost

o   Cost of rebalancing and redistribution efficiency

o   Budget and Users’ decision-making in MoD systems

o   Operator’s decision-making in MoD systems

o   Economic equilibrium and limits of economic efficiency of MoD systems (centralized methods)

o   Social welfare and theoretical efficiency of MoD Systems

Assignment 4

Revise your simulation model from assignment 3 so that now the cost of rebalancing equals revenues from ridership. How does this constraint affects the performance of your model? Discuss in the blog your view on the limitations of centralized control in MoD systems. How can technology or information change those limits?
