2016 Climate Change Symposium: Perspectives at the Water-Energy-Climate Nexus

The symposium is open to the entire campus community and the public, and has drawn large audiences interested in climate and energy issues. The 2016 focus on Water-Energy-Climate interconnections will appeal to a larger audience, as it tackles a number of pressing issues of high interest to the public: How can we continue to meet our essential water and energy needs? How can we ensure safe and reliable resource provision to cities while protecting residents from adverse impacts, such as flooding? How can we simultaneously increase the efficiency and resilience of energy and water use? How can local communities and governments best work together to solve these challenges?

We are offering this symposium as part of the 2016-17 One Book One Northwestern series since several of the topics discussed are dependent on data analysis and forecasting.

EECS Seminar: Prof. Minghua Chen, Professor, Dept. of Information Engineering, The Chinese University of Hong Kong, "Greening a Top-20 Economy: Energy-Efficient Timely Transportation of Heavy-Duty Trucks"

The EECS Department welcomes Prof. Minghua Chen, Professor, Dept. of Information Engineering, The Chinese University of Hong Kong.

Chen will present a talk entitled "Greening a Top-20 Economy: Energy-Efficient Timely Transportation of Heavy-Duty Trucks", on Thursday, October 13 at 2:30 PM in the Tech Room L440.

Abstract: In 2015, the US trucking industry hauls 70.1% of all freight tonnage and collects $726.4 billion in gross freight revenues. This impressive number corresponds to 2.3x of the Hong Kong GDP and would rank 19 worldwide if measured against countries. Meanwhile, only 4% of total vehicle population, heavy-duty trucks consume 17.6% of energy in transportation sector (including cars, trucks, airplanes, pipelines, and railways). This alerting observation, together with that fuel cost is the largest operating cost (34%) of truck operators, makes it critical to reduce fuel consumption for cost-effective and environment-friendly heavy-duty truck operation.
In this work, we consider a key yet under-explored problem in heavy-duty truck operation: timely transportation, where a heavy-duty truck travels between two locations across the national highway system subject to a hard deadline constraint. The objective is to minimize the total fuel consumption of the truck, by optimizing both route planning and speed planning. The problem is important for cost-effective and environment-friendly truck operation, and it is uniquely challenging due to its combinatorial nature as well as the need of considering hard deadline constraint. We first show that the problem is NP-Complete; thus exact solution is computational prohibited unless P=NP. We then design a fully polynomial time approximation scheme (FPTAS) that attains an approximation ratio of 1+ \epsilon with a network-size induced complexity of O(mn^2/\epsilon^2), where m and n are the numbers of nodes and edges, respectively. While achieving highly-preferred theoretical performance guarantee, the proposed FPTAS still suffers from long running time when applying to national-wide highway systems with tens of thousands of nodes and edges. Leveraging elegant insights from studying the dual of the original problem, we design a fast heuristic solution with O(m+ n log n) complexity. The proposed heuristic allows us to tackle the energy-efficient timely transportation problem on large-scale national highway systems. We further characterize a condition under which our heuristic generates an optimal solution. We observe that the condition holds in most of the practical instances in numerical experiments, justifying the superior empirical performance of our heuristic. We carry out extensive numerical experiments using real-world truck data over the actual U.S. highway network. The results show that our proposed solutions achieve 17% (resp. 14%) fuel consumption reduction, as compared to a fastest path (resp. shortest path) algorithm adapted from common practice.
Overall, we believe that de-carbonizing heavy-duty truck operation is important for the sustainable development of the trucking industry. Our work serves as a call for participation.

This is a joint work with Lei Deng and Mohammad Hajiesmaili in CUHK and Haibo Zeng in Virginia Tech.

NUTC Seminar: Carole Morey, CTA - "CTA Red & Purple Modernization (RPM): A Core Capacity Expansion"

NUTC Seminar Series presents Carole A. Morey, Chief Planning Officer, CTA to discuss "CTA Red &; Purple Modernization (RPM): A Core Capacity Expansion."

RED &; PURPLE MODERNIZATION (RPM)

CTA is undertaking the largest capital improvement project in CTA history: the Red and Purple Modernization Program (RPM). This major initiative will completely rebuild the nearly century old North Red Line from Belmont to Howard and the Purple Line from Belmont to Linden in Wilmette. As the CTA rebuilds, much needed capacity will be added in this growing residential corridor to accommodate current and future riders, and to deliver faster and smoother rides with less crowding and more frequent service.

Speaker Bio: Carole is a graduate of Northwestern University and the University of Illinois College of Law. Prior to joining the CTA, Carole practiced corporate, real estate and construction law at Sidley &; Austin and Fagel &; Haber (currently Thomson Cobum). Since joining the CTA in 2006, she has served the CTA in both the legal and infrastructure departments including three years as Vice President, Infrastructure, overseeing the CTA's capital construction program. She currently serves as CTA's Chief Planning Officer.
