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.

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.

Identifies and assesses ways of making congestion pricing equitable. The authors review notions of equity applicable to congestion pricing and explore the equity issues that arise in the context of cordon and area pricing systems and high-occupancy toll lanes.

<p>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.</p>

<p>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.</p>

<p>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.</p>

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.

<p>Policymakers need to address equity concerns early when implementing congestion pricing to improve traffic flow, as each situation is unique. Because these policies impose a cost on something that previously was not priced, it can harm lower-income drivers who will be forced to pay additional costs or be "priced off" the roads.</p>

<p>This paper investigates the optimal design of highways operated under a form of congestion pricing called value pricing. Value pricing involves dividing a highway into free and priced lanes so that in equilibrium the highway effectively operates at two levels of service, with those users placing a higher value on travel time savings selecting the faster, priced route.</p>
