Passenger Car Unit Value for Trucks using Fuzzy Model
نویسنده
چکیده
In developing countries including India, mixed traffic condition prevails on roads and highways. There is a wide variation in the static and the dynamic characteristics of different types of traffic. The only way of accounting for this non-uniformity for any traffic analysis in traffic stream is to convert all vehicles into a common unit and the most accepted unit for this purpose is passenger car unit (PCU). PCU value for a vehicle varies with traffic and roadway condition around. A number of factors have been identified affecting PCU values. The current study aims at developing a fuzzy based model for the estimation of PCU value for trucks. Fuzzy based model is of importance because of a number of independent affecting factors. Results of developed fuzzy MATLAB based model are compared with the quoted results and are found with high degree of correlation.

Impact of Vehicle Travel Characteristics on Level of Service: A Comparative Analysis of Rural and Urban Freeways
The effect of trucks on the level of service is determined by considering passenger car equivalents (PCE) of trucks. The current version of Highway Capacity Manual (HCM) uses a single PCE value for all tucks combined. However, the composition of truck traffic varies from location to location; therefore, a single PCE value for all trucks may not correctly represent the impact of truck traffic at...
متن کاملApplication of Fuzzy Logic to Vehicle Classification Algorithm in Loop/piezo-sensor Fusion Systems
Individual vehicle information, especially, vehicle classification data play a key role in Advanced Traffic Management and Information Systems (ATMIS). In inductive loop and piezo-sensor fusion systems, traffic data such as the vehicle length and the distance between axles are used for vehicle classification. However, classification errors often occur in distinguishing passenger cars from small...
متن کاملFinite element analysis of fatigue damage in passenger-car diesel engine cylinder head under cyclic thermo-mechanical loadings
In this article, the thermo-mechanical fatigue lifetime of the cylinder head of a passenger-car diesel engine has been estimated. At the first stage, stress and strain distributions in the cylinder head have been calculated using the two-layer visco-plastic model, available in the ABAQUS software. The calibration of the model was performed, using correlating of simulated hysteresis curves and l...

This paper focuses on the design of adaptive cruise control (ACC) which was implemented on a passenger car based on sliding mode control (SMC) of throttle valve combining with fuzzy logic control of brake pedal. An important feature of the new adaptive cruise control system is the ability to maintain a proper inter-vehicle gap based on the speed of host vehicle and headway way. There are three ...
