The inhabitants of Australia's larger cities suffer from frequent traffic jams. Many see this as an inescapable fact of city life, but its root cause is overuse of a common resource — the urban road network. Most roads are nominally 'free' to drive on, resulting in demand for many roads that...

This paper reviews theoretical issues surrounding transport safety modeling and the implications for road safety policy. The behavioral mechanisms that affect transport safety are typically not considered in safety modeling. These issues are discussed in the context of trade-offs between...

We use a public referendum on a new air traffic concept in Berlin, Germany as a natural experiment to analyze how the interaction of tenure and capitalization effects shapes the outcome of direct democracy processes. We distinguish between homevoters, i.e., voters who are homeowners, and...

To assess the likely effects of population ageing on the outcomes of direct democracy, we analyze the effect of age on voting decisions in public referenda. To this end, we provide the first quantitative review of the literature and a case study of the Stuttgart 21 referendum on one of the...

Neoclassical microeconomic theory postulates that the value of time is a fraction of an individual’s hourly wage. When taken to the marketplace, however, this value appears to depart from theoretical predictions. To reconcile them, we conceptualize the value of urgency, which reflects...

The effects of autonomous vehicles (AVs) on urban forms are modeled and analyzed. Vehicles are used for commute between peripheral home and central work, and require space for day parking. An advantage of AVs is that they can return home for day parking, relieving central land for other uses....

Efficient use of the transport systems can increase well-being and ensure gains for the society. The reduction of the costs involved in transport operation can occur through management, investments or using more efficient infrastructures. Well-being gains are weighted based on economic theory,...

The effects of planning initiatives aimed at increasing bicycle use have been little studied in relation to decreased auto use, injuries and pollution. As most programs promote the idea that public investments in bicycle lanes, traffic calming engineering of streets and valuing bicycling as...

In 1992, Amsterdam's voters pushed for a more-aggressive autoluw (`nearly car free'') policy, but progress has been slow. Hourly parking tariffs are the highest in the country, but more cars than ever park in Amsterdam. We explore this promise-results gap in a spatial comparison of the price of...
