Haul Routing: an Overlooked Factor in Environmentally Driven Road Decommissioning
نویسنده
چکیده
Stream sedimentation concerns might probably be incorporated into the road design process as a simplified, intuitive thumbnail model. Road Density (RD) and Stream Crossing Density (SCD) however guide designers towards minimizing minor, unused spur roads that have minimal sediment impacts. Crossing Area Served (CAS) on the other hand, focuses design attention towards the most heavily traveled segments, tending to shift them away from the stream network and towards a ridge alignment. A case study suggest that CAS better identifies areas of high sediment delivery and the design options that reduce this sediment.

A new developed model to determine waste dump site selection in open pit mines: An approach to minimize haul road construction cost
Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...
متن کاملApplication of Chaos Theory in Hazardous Material Transportation
Risk factors are generally defined and assigned to road networks, as constant measures in hazmat routing problems. In fact, they may be dynamic variables depending on traffic volume, weather and road condition, and drivers' behavior. In this research work, risk factors are defined as dynamic variables using the concept of chaos theory. The largest Lyapunov exponent is utilized to determine the ...
متن کاملA ROUTING METHODOLOGY FOR HAZARDOUS MATERIALS TRANSPORTATION TO REDUCE THE RISK OF ROAD NETWORK
Abstract: The shipments of hazardous materials (HAZMATs) induce various risks to the road network. Today, one of the major considerations of transportation system managers is HAZMATs shipments, due to the increasing demand of these goods (because it is more used in industry, agriculture, medicine, etc.), and the rising number of incidents that are associated to hazardous materials. This paper ...
متن کاملLagging Behind – The Emerging Influence of Jet Lag Symptoms on Road Safety
Road traffic accidents are the leading cause of death in international travelers. With the growth of international travel, the number of visitors who rent a vehicle upon arrival at their destination by air or by sea is expected to increase. Jet lag is a well-recognized maladaptation to international travel across multiple time zones. Little is known about the possible influence of jet lag sympt...
متن کاملTrends in spatial patterns of heavy metal deposition on national park service lands along the Red Dog Mine haul road, Alaska, 2001–2006
Spatial patterns of Zn, Pb and Cd deposition in Cape Krusenstern National Monument (CAKR), Alaska, adjacent to the Red Dog Mine haul road, were characterized in 2001 and 2006 using Hylocomium moss tissue as a biomonitor. Elevated concentrations of Cd, Pb, and Zn in moss tissue decreased logarithmically away from the haul road and the marine port. The metals concentrations in the two years were ...
