CFR Backgrounder: Transportation Infrastructure: Moving America

Backgrounder: Transportation Infrastructure: Moving America
Source: Council on Foreign Relations

Infrastructure is critical to economic growth, but the aging U.S. transportation system suffers from insufficient investment. As this CFR Progress Report and Scorecard, Road to Nowhere, explains, other nations are building new highways as the United States’ crumble. U.S. transportation fell from fifth in the World Economic Forum’s rankings in 2002 to twenty-fourth in 2011, passed by nations such as Spain, South Korea, and Oman. Making a U-turn will take some time since major infrastructure projects require several years to plan and execute.

The decline can be attributed to a general trend of under-investment in infrastructure; the American Society of Civil Engineers (ASCE) has only awarded overall grades of D or D+ to U.S. infrastructure in all five report cards issued from 1998 to 2013. Current infrastructure requires more investment—for instance, one in nine U.S. bridges are structurally deficient—while new projects are needed to address issues such as road congestion, which costs American drivers $101 billion annually in wasted time and fuel, and airport delays that are a $22 billion drag on the economy.

While experts have been warning about crumbling infrastructure for more than a decade, the federal government has not addressed underinvestment.

Urban Computing: Concepts, Methodologies, and Applications

Urban Computing: Concepts, Methodologies, and Applications
Source: Microsoft Research

Urbanization’s rapid progress has modernized many people’s lives, and also engendered big issues, such as traffic congestion, energy consumption, and pollution. Urban computing aims to tackle these issues by using the data that has been generated in cities, e.g., traffic flow, human mobility and geographical data. Urban computing connects urban sensing, data management, data analytics, and service providing into a recurrent process for an unobtrusive and continuous improvement of people’s lives, city operation systems, and the environment. Urban computing is an interdisciplinary field where computer sciences meet conventional city-related fields, like transportation, civil engineering, environment, economy, ecology, and sociology, in the context of urban spaces. This article first introduces the concept of urban computing, discussing its general framework and key challenges from the perspective of computer sciences. Secondly, we classify the applications of urban computing into seven categories, consisting of urban planning, transportation, the environment, energy, social, economy, and public safety & security, presenting representative scenarios in each category. Thirdly, we summarize the typical technologies that are needed in urban computing into four folds, which are about urban sensing, urban data management, knowledge fusion across heterogeneous data, and urban data visualization. Finally, we outlook the future of urban computing, suggesting a few research topics that are somehow missing in the community.

UK — Benefits of Investing in Cycling

Benefits of Investing in Cycling (PDF)

Investing in cycling will generate benefits for the whole country, not just those using a bike to get around. Eleven benefits are summarised here which can help solve a series of health, social and economic problems. This report shows how investing in cycling is good for our transport systems as a whole, for local economies, for social inclusion, and for public health.

Creating a cycling revolution in the UK requires sustained investment. In European countries with high cycling levels, levels of investment are also substantially higher than in the UK. The All-Party Parliamentary Cycling Inquiry has recommended a minimum of £10 annually per person, rising to £20, which would begin to approach the spending levels seen in high-cycling countries.

Investing in cycling will enable transport authorities to start putting in place the infrastructure we need to ensure people of all ages and abilities can choose to cycle for short everyday trips. As well as making cycle journeys more pleasant, safer and faster, it sends the signal that cycling is a normal way to travel. This is important because the perception of cycling as a marginal and minority mode is off-putting to many people.

Should We Build More Large Dams? The Actual Costs of Hydropower Megaproject Development

Should We Build More Large Dams? The Actual Costs of Hydropower Megaproject Development

A brisk building boom of hydropower mega-dams is underway from China to Brazil. Whether benefits of new dams will outweigh costs remains unresolved despite contentious debates. We investigate this question with the “outside view” or “reference class forecasting” based on literature on decision-making under uncertainty in psychology. We find overwhelming evidence that budgets are systematically biased below actual costs of large hydropower dams — excluding inflation, substantial debt servicing, environmental, and social costs. Using the largest and most reliable reference data of its kind and multilevel statistical techniques applied to large dams for the first time, we were successful in fitting parsimonious models to predict cost and schedule overruns. The outside view suggests that in most countries large hydropower dams will be too costly in absolute terms and take too long to build to deliver a positive risk-adjusted return unless suitable risk management measures outlined in this paper can be affordably provided. Policymakers, particularly in developing countries, are advised to prefer agile energy alternatives that can be built over shorter time horizons to energy megaprojects.

Ranking Each State’s Highway Conditions and Cost-Effectiveness: Wyoming, Nebraska and South Dakota Are Best; Hawaii, Alaska and New Jersey Are Worst

More money is going to state highways, but there has been very little progress in improving their condition according to the 21st Annual Highway Report by Reason Foundation.

“Many of the easiest repairs and fixes to state highway and bridge systems have already been made and the rate of progress is slowing down,” said David T. Hartgen, lead author of the Annual Highway Report since 1984. “A widening gap also seems to be emerging between states that are still making improvements and a few states that are really falling behind on highway maintenance and repairs.”

Spending on state-owned roads totaled $132 billion in 2012, up 6 percent from 2011. Spending varied wildly from state to state according to the Annual Highway Report. South Carolina and West Virginia spent just $39,000 per mile of road in 2012 while New Jersey spent over $2 million per state-controlled mile. Rhode Island, Massachusetts, California and Florida were the next biggest spenders, outlaying more than $500,000 per state-controlled mile.

Economic & Environmental Impact of Traffic Congestion in Europe & the US

With people in Europe and the US currently wasting on average 111 hours annually in gridlock, the impact of traffic congestion on individual driver’s time is well understood. However, new research shows traffic congestion actually does much more than test our patience. It’s a significant drain on our wallets as well our economies.

A new report by INRIX in collaboration with one of the world’s leading economic think tanks, the Centre for Economics and Business Research (CEBR), quantifies the cost of traffic congestion on individual households and national economies in the U.S., U.K., France and Germany. This is the first study of its kind to forecast the projected increases in these costs in these countries and their most congested cities between 2013 and 2030. Driven by urbanization and increased GDP per capita over the next 17 years, a few of the key findings include:

  • The combined annual cost of gridlock to these countries is expected to soar to $293.1 billion by 2030, almost a 50% increase from 2013.
  • Over this period, the cumulative cost of congestion for these economies combined is estimated to be a staggering $4.4 trillion.
  • The overall economic impact is greatest in the U.S. where the estimated cumulative cost of traffic congestion by 2030 is $2.8 trillion – the same amount Americans collectively paid in U.S. taxes last year.
  • However the UK (at 66%) and London (at 71%) will see the greatest annual rise in the cost of congestion by 2030, mainly as a result of seeing the highest increase in urbanization
  • At the individual level, traffic congestion cost drivers $1,740 last year on average across the four countries. If unchecked, this number is expected to grow more than 60% to $2,902 annually by 2030.
