Analyses have been made of the effects of environmental controls and planning at regional, subarea, and project levels. The results obtained at the regional level are reviewed for a proposed highway development around Baltimore, Md. The findings for both short-term and long-term effects of alternative transport policies are summarized in respect of population and employment, economic indicators...

This paper summarizes basic principles for transportation planning. It describes conventional transport planning, which tends to focus on motor vehicle traffic conditions, and newer methods for more multi-modal planning and evaluation. Multi-Modal Transportation Planning Victoria Transport Policy Institute 1 Conventional Transportation Planning Multi-modal planning refers to planning that consi...

I recent years there has been a growing concern over the congested conditions of our urban highway facilities. The continuing escalation of adverse driving conditions in major urban areas has generated a feeling of discontent among automobile owners and transportation planners alike. One major factor that has contributed to this feeling of dissatisfaction is the rapid pace with which many of th...

This paper describes the design and evolution of a GIS-based corridor route planning methodology called Analytic Minimum Impedance Surface (AMIS). A local State Highway Agency (SHA) requested an analytic methodology that would facilitate choice of a route corridor for a section of a proposed Interstate highway connector in the southeastern U.S. The SHA’s specification demanded a robust, quantit...

Recent research in automated highway systems has ranged from low-level vision-based controllers to highlevel route-guidance software. However there is currently no system for tactical-level reasoning. Such a system should address tasks such as passing cars, making exits on time, and merging into a traffic stream. Our approach to this intermediate-level planning combines a distributed reasoning ...

The Federal Emergency Management Agency (FEMA) has identified the four phases of disaster related planning as mitigation, preparation, response, and recovery. The recovery phase is characterized by activity to return life to normal or improved levels. Very little research considers the recovery phase, which encompasses restoring services and rebuilding disaster stricken areas of the highway tra...

This paper presents some results of a recent study that has evaluated data accuracy, efficiency, and costeffectiveness of this remote-sensing LIDAR technology as compared to the conventional aerial photogrammetry and ground total station methods for terrain data acquisition and mapping. An overview of airborne laser mapping technology for producing digital terrain models and digital databases f...

BACKGROUND Understanding the ecological consequences of roads and developing ways to mitigate their negative effects has become an important goal for many conservation biologists. Most mitigation measures are based on road mortality and barrier effects data. However, studying fine-scale individual spatial responses in roaded landscapes may help develop more cohesive road planning strategies for...

|This paper deals with a trajectory planning problem that we call thèhighway problem'. It consists in planning a time-optimal trajectory for a mobile which is travelling in a structured workspace amidst moving obstacles and is subject to constraints on its velocity and acceleration. By structured workspace, we mean that there exists lanes characterized by one-dimensional curves along which the ...
