Acceleration Characteristics of Vehicles in Rural Pennsylvania
نویسنده
چکیده
The objective of the paper is to determine the acceleration characteristics of vehicles in rural Pennsylvania. The floating car method was used to observe the acceleration characteristics during overtaking maneuvers. The acceleration characteristics from rest were observed manually. Various acceleration values for different vehicles were determined. The maximum value of acceleration observed was that of SUVs and the minimum value of acceleration observed was that of buses. A comparison of observed passing sight distances on a two lane highway in rural Pennsylvania with that of AASHTO was made. The observed passing sight distances were shorter by 18% and 8% at 35 km/h and 85 km/h design speeds. This is because at lower design speeds, the observed acceleration was higher.

Introduction: Cars can cause whole body vibration with different intensities which result in discomfort and musculoskeletal disorders in the exposed persons. Heavy mine vehicles based on the working environment, capacity, and power can produce considerable vibration to be transferred to the operator. The purpose of this study was to assess whole body vibration in the drivers of heavy mine vehic...
متن کاملIntelligent identification of vehicle’s dynamics based on local model network
This paper proposes an intelligent approach for dynamic identification of the vehicles. The proposed approach is based on the data-driven identification and uses a high-performance local model network (LMN) for estimation of the vehicle’s longitudinal velocity, lateral acceleration and yaw rate. The proposed LMN requires no pre-defined standard vehicle model and uses measurement data to identif...

This paper presents the capacitated Windy Rural Postman Problem with several vehicles. For this problem, two objectives are considered. One of them is the minimization of the total cost of all vehicle routes expressed by the sum of the total traversing cost and another one is reduction of the maximum cost of vehicle route in order to find a set of equitable tours for the vehicles. Mathematical ...
