Steering Clear of Tort Claims
Tort liability has become a major issue for today's highway engineer. Claims against state highway departments charging that deficient roadways caused or contributed to traffic...
The Diagnosis of Pavement Ills
The paper defines the 'health' of a road pavement in terms of parameters of serviceability, safety and structural integrity and defines 'illness' as any departure from 'healthy' values...
Successful High Traffic Chip Seal Construction
Chip seal coats are used to extend pavement service life by reducing water and air infiltration and improving skid resistance. Application of chip seals is usually limited to low-traffic...
HOV Lessons
As traffic congestion worsens, transportation planners are struggling to squeeze out every last bit of available roadway capacity. High-occupancy vehicle lanes are one solution, but aren't...
Restricting Rockfalls
Predicting and controlling rockfalls has always been a high priority in Colorado, where many mountainous roads pass through hazardous rockfall areas with extensive and highly variable...
Settling Down Easy
In order to more fully participate in the international and Asian Pacific aviation network, it was decided to establish a highly efficient 24-hour a day operation at the New Kansai International...
Tomorrow's Toll Road
Techniques using automatic vehicle identification (AVI) currently provide the most efficient form of electronic toll collection. Several systems have been installed in the U.S. in the...
Houston Moves Forward Again
The National Transportation Plan, as released by Transportation Secretary Samuel Skinner, advocates the construction of toll roads and calls on local governments to devise and finance...
Trouble on the Waterways?
Crumbling highways and bridges can cripple the U.S. economy. A lesser known transportation problem is the condition of our inland waterway system. Waterways are a cost-efficient, environmentally-sound...
