On the cover: Southwest Airlines is an experienced hedger and uses financial instruments or hedging contracts to decrease its exposure to fuel price volatility. In “Airline Fuel Hedging: Do Hedge Horizon and Contract Maturity Matter?” Siew Hoon Lim and Peter Turner examine whether the length of hedging period and distance to contract maturity affect the effectiveness of jet fuel cross hedging.

On the cover: Remote areas of the central and northern plains states have little alternative to railroads in the transport of wheat. Wheat shipments involve large scale movements of low value bulk commodities over long distances. Trucks are not competitive for these movements and many wheat origins are remote from barge loading locations. The implications of these facts are examined by Michael Babcock and Bebonchu Atems in “Intramodal and Intermodal Competition Impacts on Railroad Wheat Rates.” Disclaimer: The facts, opinions, and conclusions set forth in the articles contained herein are those of the authors and quotations should be so attributed.

On the cover: Highway-rail grade crossings (HRCGs) are conflict points for highway users and railroads and are an important safety issue. In “Severity of Pedestrian Crashes at Highway-Rail Grade Crossings,” Aemal Khattak and Li-Wei Tung quantify the impacts of various factors on three severity levels of pedestrian injuries at HRCGs. Wei (David) Fan, Martin Kane and Elias Haile in “Analyzing Severity of Vehicle Crashes at Highway-Rail Grade Crossings” explore the impact of various explanatory variables on three different severity levels of vehicle crashes at HRCGs.

On the cover: Congestion on urban freeways during peak times of the day is a universal transportation problem. Shy Bassan investigates the traffic efficiency gained by restricting heavy truck traffic during peak hours in “Review, Experimental Evaluation and Policy Considerations of a Directional Time of Day Truck Restriction on Highways.” He found that prohibiting trucks in all lanes during the 4-6 p.m. period improved average travel time, total travel time, and average traffic speed by 8%?12%.

On the cover: Ju Dong Park and Won W. Koo identify the economic and non-economic factors that affect U.S. air travel in “The Magnitudes of Economic and Non-Economic Factors on the Demand for U.S. Domestic Air Travel.” The authors find that airfare, income, seasonality, and mergers play significant roles in the demand for airline passenger travel.

On the cover: Good railroad service is essential to a prosperous agriculture industry. Railroads transport grain long distances to consumption centers. Yet there have been few railroad demand studies in recent years. Michael W. Babcock and Philip G. Gayle estimate railroad demand functions for various grains in “Specifying and Estimating a Regional Agricultural Railroad Demand Model.” General Editors: Michael W.
