RAND research addresses the challenges of developing, managing, and protecting energy, transportation, water, communications, and other critical infrastructure throughout the world.
Mileage-fee rates could be structured to reduce congestion, harmful emissions and excessive road wear, and the enabling technology could support a range of value-added services offering greater convenience and safety for motorists, writes Keith Crane.
This paper uses a stated choice experiment to quantify individuals' tradeoffs between privacy and security within a real-life context, namely rail travel in the UK.
Congress should take the opportunity provided by the pending reauthorization of the federal transportation bill to consider new ways to fund the U.S. transportation system, shifting from indirect fees such as fuel taxes to ones that charge drivers directly for the miles they travel.
This study of perceptions of drinking water in a California school district found that school staff and public health officials have a range of concerns about water quality and availability; as some schools move to replace sugary drinks in schools and develop policies to promote water consumption, they should explore ways of addressing these concerns.
Much of the current debate concerning civil liberties and security is adversarial, and little robust research data informs these arguments.This paper outlines the results of a study that attempts to objectively understand the real privacy, liberty and security trade-offs made by individuals, so that policymakers can be better informed about the preferences of individuals with regard to these important issues.
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.
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.
The results of this study suggest that improving neighborhood environments and increasing the public's use of light rail transit systems could provide improvements in health outcomes for millions of individuals.
This study investigated the applicability of Multinomial logit (MNL) models to predict the proportion of crashes by collision type and to estimate crash counts by collision type.
Restrictions on fast-food chain restaurants in South Los Angeles are not addressing the main differences between neighborhood food environments and are unlikely to improve the diet of residents or reduce obesity.
The availability of energy-dense snack foods in grocery stores plays a role in the weight status of neighborhood residents.
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.
This research is an initial step toward creating policies to address autonomous vehicle technologies—which have the potential to enormously benefit humankind but raise substantial concern about tort liability for damages that may result from their use.
A resilient transportation system is one that minimizes both the initial effect of the disruption and the time required to return the system to normal operations.
Even though research on group behavior is still a comparatively new field in transportation, rapid progress has been made since the beginning of the 21st century.
The increase in value of time (VOT) with trip length is more likely to be due to heteroskedasticity (in the data studied) and the underlying VOT is therefore not increasing with distance at an individual level.
Planning for urban systems
It is assumed that higher quality recreation facilities promote physical activity and serve communities better. The authors tested this assumption by comparing changes in the use of an expanded and renovated skate park (a facility for skateboarding) and a modernized senior citizen's center to two similar facilities that were not refurbished.
Discusses the possibilities and options for America if neighboring country Mexico should become a failed state.
Chronic medical and mental illness and disability increase vulnerability to disasters.
There is a public interest in ensuring that infrastructure systems are appropriately protected and prepared for disruptions.
