Remode, reprice, reshape

My friends at GoGet, an Australian CarSharing company, released the report “Let’s Fix Congestion!”. While I am allergic to the congestion framing, since obviously cities should be designed around accessibility,  it is widely believed to be necessary to talk about congestion to get broader buy in from the media for any transport issue around here.

Remode Reprice Reshape
Remode Reprice Reshape

The strategy in the report is quite sound for a soundbyte:  Remode, reprice, reshape. Quoting from the report:

Remoding

Remoding is a strategy that shifts more people out of the dominant mode, the private vehicle, into other modes such as public transport, active transport, and shared mobility. This latter area includes on-demand sharing, an approach that can offer compelling convenience and affordability for the transport consumer.

Repricing

We need to address the economic and taxation policies that have preferenced the private car over other transport modes, and in turn generate congestion.

Currently the true cost of using a private vehicle is kept from the consumer’s view, whether it involves not accurately pricing parking or congestion’s effect on productivity.

Reshaping

Our cities have been designed around the private vehicle, preferencing space for cars over space for people.

We need to re-imagine our built environments and associated land use policies. Density is not a bad word if it is density done right. Density done right means an abundance of local shops and services which encourage abundant local living. Local living encourages local transport, often active, public and shared, and disincentivises the private vehicle, particularly when combined with smart parking policies.

This slogan is of course is adapted from the environmental movement’s Reduce, Reuse, Recycle, part of the Waste Hierarchy. [Replace and Recover and sometimes added to this list.]

But did you know Franklin Delano Roosevelt’s New Deal strategy was “Relief, Recovery, and Reform”? The Three Rs have a long history.

Road Scholars: New Research in Travel Time, Speed, and Reliability Data

How climate change impacts infrastructure: experts explain

The University of Sydney released a news article: How climate change impacts infrastructure: experts explain

From fires in the Amazon and in Australia, to flash flooding in Europe, right across the globe we are witnessing the impact of climate change on the environment. But how does a changing climate affect key infrastructure? Engineering experts explain.

How does climate change affect transport infrastructure?

School of Civil Engineering academic, Professor David Levinson is a transport engineering expert who says transport infrastructure both contributes to climate change, but can also be affected by it.

“The issue goes two ways in transport. Typically, road and air transport are considered major contributors to climate change, making up 23 percent of CO2 emissions,” said Professor Levinson.

“But transport is also vulnerable, particularly due to so many facilities like roads and bus terminals being in flood zones, for instance New Jersey Transit lost $US120 million in damage to buses after Hurricane Sandy.

“Many transport facilities are also below grade, tunnels like those in the New York Subway were severely damaged from flooding during Sandy. Airports being at low elevations along the coast are at risk of sea-level rise. Extreme heat can cause road buckling, freeze-thaw cycles cause pavement cracking and potholes.

“Extreme weather increases the variability of weather, and roads designed for a particular climate range may fail more quickly. All of these add costs to design and retrofit, as well as decreasing reliability for users.”

 

A Review of Game Theory Models of Lane Changing

Recent working paper:

Driver lane-changing behaviours have a significant impact on the safety and the capacity of the vehicle-based traffic system, therefore, modeling lane-changing maneuvers has become an essential component of driving behaviour analysis. Among microscopic LC models, game theory based lane-changing models highlight the interaction or competition of drivers, which reveal a more realistic image of driving behaviours compared to other classic models. However, the potential of game theory to describe the human driver’s lane-changing strategies is currently under-estimated. This paper aims to review the recent development of game theoretic models that are classified according to their different methodologies and features. They are designed for both human-driven (User-optimal) and autonomous vehicles (User and system-optimal), and we hope they can find applications in future AV industries.

Trains, trams, and terraces: population growth and network expansion in Sydney: 1861-1931

Recent working paper:

This paper examines the changes that occurred in the tram and train networks and density of population in Sydney between the early 1860s and 1930s when both trains and trams were developing. A set of statistical analysis has been conducted using panel data representing 593 districts of Greater Sydney at suburb (neighborhood) level over each decade from 1861 to 1931. We find that trams and population density are positively associated in a positive feedback process, tram deployment leads population growth and population growth leads tram deployment, both satisfying a Granger causality test.

Commute Mode Share and Access to Jobs across US Metropolitan Areas

Recently published:

How much of the variation in transit mode share is attributable to accessibility is not well understood, despite its significant policy implications. It is hypothesized that better transit accessibility leads to higher transit mode share. This paper explains block-group level transit mode share using transit accessibility in a logistic model for 48 major US metropolitan areas. Transit accessibility alone explains much of the variation in transit mode share for all 48 regions despite their geographical differences (adjusted R2 0.61, potential accessibility); models for individual cities have stable and interpretable parameters for transit accessibility. The models better explain mode share in cities with higher person weighted transit accessibility and larger populations; an adjusted R2 of 0.76 is achieved for New York City with transit accessibility as the only explanatory variable. Additional automobile accessibility and income variables modestly improve model fit. Time-decay functions fitted to accessibility measures better explain mode choice than the isochrone accessibility, and suggest the catchment area affecting transit mode choice to be within 35 minutes. This work contributes to the understanding of transit mode share by solidifying its link with accessibility, which is determined by the structure of the transport network and land development.

Shortest paths, travel costs, and traffic

Recent working paper:

This study focuses on path flow for road network, as the sum of individual route choices from individual travelers, associated with specific path type for each cost fac- tor of auto travel that finds the optimal route with the minimum cumulative cost from the perspective of the corresponding cost analyst interest. The considered cost factors include time, safety, emission, and monetary costs, as well as their composite, internal and full cost of travel. We further explore the extent to which each cost factor explains the observed link traffic flows given an estimated home-to-work demand pattern. The results of the Minneapolis – St. Paul metropolitan area indicate that flows from multiple path types, associated with internal cost components, additionally to the factor of distance, provides the best fit.
