Deciding Alternative Left Turn Signal Phases Using Expert Sytiems

چکیده
T Texas Transportation Institute (lTI) conducted a study to investigate the feasibility of applying artificial intelligence (AI) technology and expert systems (ES) design concepts to a traffic engineering problem. Prototype systems were developed to analyze user input, evaluate various reasoning, and suggest suitable left turn phase treatment. These systems were developed using AI programming tools on IBM PC/XT/ATcompatible microcomputers .]”3 Two slightly different systems were designed using AI languages; another was built with a knowledge engineering tool. These systems include the PD PROLOG* and TURBO PROLOG AIt programs, as well as the INSIGHT 1$ Production Rule Language .’-’o

Developing an Analytical Model and Simulation of The Contraflow Left-Turn Lane at Signalized Intersections
At some intersections, excessive queue lengths may spill out of the left-turn bay and block the through lanes, jeopardizing level of service for the entire intersection. One of the most effective plans recently presented by the researchers is the "Contraflow left-turn lane" (CLL) In this method, left-turn vehicles will use the nearest lane in the opposite direction in addition to the usual left...
متن کاملCapacity Matching Based Model for Protected Left Turn Phases Design of Adjacent Signalized Intersections along Arterial Roads
A protected left turn phase is often used at intersections with heavy left turns. This may induce a capacity gap between adjacent intersections along the arterial road among which only parts of intersection are with protected left turn phase. A model for integrated optimization of protected left turn phases for adjacent intersections along the arterial road is developed to solve this problem. T...
متن کاملReducing the respiratory motion artifacts in PET cardiology: A simulation study
Introduction: There are several technical features that make PET an ideal device for the noninvasive evaluation of cardiac physiology. Organ motion due to respiration is a major challenge in diagnostic imaging, especially in cardiac PET imaging. These motions reduce image quality by spreading the radiotracer activity over an increased volume, distorting apparent les...
متن کاملPerformance Evaluation of the Diverging Diamond Interchange In Comparison With the Conventional Diamond Interchange
The decision making process in transportation is often about making a choice between alternative solutions to a problem. To select the best alternative, the decision should be based on results from a careful study of the implications of the alternatives. This paper presents the results of a study comparing two alternative interchange designsDiverging Diamond and Conventional Diamond Interchange...
متن کاملI Efficiencyof Dual Lefi - Turn lane Intersections In Charlotte : A Study UsingTRAFhE 1 ’ ’ SlM
As traffic volumes increase on major intersecting arterials, the transportation engineer’s challenge is one of optimizing through traffic while providing adequate opportunities for leftturning vehicles. Increasing traffic volumes not only provide a proportionately higher number of leftturning vehicles, but also make it more difficult to negotiate a left turn due to increased opposing traffic. T...
