I will be presenting at CUPPA’s Friday Forum:
” Network Structure and Travel Behavior”

Abstract:
Transportation networks have an underlying structure, defined by the layout, arrangement and the connectivity of the individual network elements, namely the road segments and their intersections. The differences in network structure exist among and between networks. This presentation argues that travellers perceive and respond to these differences in underlying network structure and complexity, resulting in differences in observed travel patterns. This hypothesized relationship between network structure and travel is analyzed using individual and aggregate level travel and network data from metropolitan regions across the U.S. Various measures of network structure, compiled from existing sources, are used to quantify the structure of street networks. The relation between these quantitative measures and travel is then identified using econometric models.

Washington Post: The re-building of Tysons Corner and Tysons Corner Center’s oil pipeline from Alaska
Pioneer Press $4 million to make walking to school safer – and no one’s walking: “Of 620 students at Bailey, not one walks – not even those who live one block away.”
LA Times: Neutrino jokes hit Twittersphere faster than the speed of light: “-Neutrino. Knock knock.”
NY Times: New York No Longer Has Worst Commuting Time : “Maryland moved into first place last year with an average of 31.82 minutes, compared with New York’s 31.27 — meaning that it took Marylanders about 33 seconds longer to get to work than New Yorkers.” [This is state averages rather than metro]
Dan Sperling and Richard Forman in Solutions Journal: The Future of Roads: No Driving, No Emissions, Nature Reconnected : “Suppose we could move gloriously and quietly along in our own comfortable car compartment some 20 feet high between the trees, yet with no engine running, no fossil fuel use, no greenhouse gas emissions, and no need to watch the road (Figure 1). Or, we could zip along in channels dug just below ground level and topped with translucent covers. No unpredictable drivers to worry about or vehicles to crash into. No driver fatigue, indeed, no driving. Barely any traffic noise. We watch nature around us, remember the bad old days of polluting traffic, play family games, work on the computer, or read. When ready to return to ground level, we simply take manual control of our fully charged battery “pod” car and drive off on local roads to our destination.”
TED: Dennis Hong: Making a car for blind drivers : “Using robotics, laser rangefinders, GPS and smart feedback tools, Dennis Hong is building a car for drivers who are blind. It’s not a “self-driving” car, he’s careful to note, but a car in which a non-sighted driver can determine speed, proximity and route — and drive independently.” [Oh just build the self-driving car already]
