Journal Article
This paper presents results of an assessment of the state of research on decoupling the relationship between vehicle travel and economic growth.
Project
RAND Europe is expanding the original traffic model it developed for Copenhagen to include time-of-day choice for car drivers. Doing so will allow city planners to assess the effectiveness of different charging policies aimed at reducing congestion levels.
Report
The UK Migration Advisory Committee asked RAND Europe to examine how migration is likely to impact transport networks and congestion. The resulting research is one of the first studies using UK data to provide an empirical evidence base about migrants' travel behavior and impacts.
Journal Article
In the 1990s, the usual assumption for an appraisal of road schemes in the UK was that total volumes of traffic were not affected by the capacity provided by the schemes. This assumption was questioned by the influential SACTRA committee in 1994.
Journal Article
This paper explores how alternative pricing and operating policies influence revenue generation, level of service, and travel time costs for high occupancy toll (HOT) lane facilities.
Journal Article
Identifies and assesses ways of making congestion pricing equitable.
Commentary
While traffic congestion plagues many cities, Los Angeles stands apart, routinely ranking first for both total and per-capita congestion delay, with an estimate annual cost at close to $10 billion, writes Paul Sorensen.
Journal Article
This article discusses the rationale for pricing strategies as an option for reducing traffic congestion in Los Angeles. Only pricing resist the effects of triple convergence. By increasing the cost of driving or parking in the busiest areas or corridors during the busiest times of day, pricing measures manage the demand for peak-hour travel, in turn reducing congestion. Once traffic flow improves, the prices remain in place, thus deterring excessive convergence on the newly freed capacity. Pricing strategies offer two additional benefits: it generates revenue to support needed transportation investments, and it enables more efficient use of existing road capacity, because roads on which traffic flows smoothly can carry far more vehicles per lane per hour than roads snarled in stop-and-go congestion. It is useful to think of pricing as a means of managing peak-hour travel demand rather than reducing it.
Journal Article
A novel and practical quality improvement tool can help hospitals and clinics plan for and respond to the psychological consequences of catastrophic events that create a surge of psychological casualties presenting for health care.
Journal Article
The authors developed an integrated policy framework that could offer the greatest prospects for relieving traffic congestion and improving transportation options in the Los Angeles region. The framework encompasses three key components: --Rely on pricing to manage peak-hour demand, raise needed revenue, and promote more efficient use of existing capacity. --Significantly improve transit and other alternative modes. --Continue to improve the efficiency of the road network, but shift the emphasis from moving cars to moving people. A noteworthy characteristic of these recommendations is that many--particularly those that involve pricing--are certain to stir controversy.
News Release
Policymakers need to address equity concerns early when implementing congestion pricing to improve traffic flow, as each situation is unique and must be evaluated on a case-by-case basis.
Report
Some congestion pricing projects have been undertaken to address traffic congestion, but some worry that congestion pricing is inequitable. This report looks at the evidence that might support or negate this claim.
Journal Article
This paper investigates the optimal design of highways operated under a form of congestion pricing called value pricing.
News Release
A comprehensive look at Los Angeles traffic debunks common myths about the metropolitan region's traffic patterns and details the reasons why congestion is so bad -- and why it will get worse in the coming years without significant policy changes.
Research Brief
This research brief identifies key factors determining L.A. transportation policy needs and makes 13 recommendations that together could reduce congestion -- arguably the worst in the country -- substantially within five years.
Report
The authors of this book recommend strategies for reducing traffic congestion in the Los Angeles area that could significantly enhance quality of life, reduce economic and environmental costs, and improve social justice within about five years.
Commentary

Past Event
What policy options are available to mitigate Los Angeles' notoriously congested roadways? RAND transportation expert Martin Wachs and a panel of regional stakeholders and policymakers will discuss realistic approaches to addressing the region's worsening congestion.
Report
Consideration of the use of V/STOL aircraft to reduce air traffic congestion at the major New York area airports while increasing overall terminal capacity.
Report
A brief consideration of the problems of peak-hour traffic congestion. The author suggests that, because we cannot afford to provide the facilities necessary to eliminate congestion, we will have to either continue to live with rush-hour congestion ...
