Eco-Driving Systems For Connected Automated Vehicles: Multi-Objective Trajectory Optimization, Ke Huang, Xianfeng Yang
Mineta Transportation Institute
This study aims to leverage advances in connected automated vehicle (CAV) technology to design an eco-driving and platooning system that can improve the fuel and operational efficiency of vehicles during freeway driving. Following a two-stage control logic, the proposed algorithm optimizes CAVs’ trajectories with three objectives: travel time minimization, fuel consumption minimization, and traffic safety improvement. The first stage, designed for CAV trajectory planning, is carried out with two optimization models. The second stage, for real-time control purposes, is developed to ensure the operational safety of CAVs. Based on extensive numerical simulations, the results have confirmed the effectiveness of the …

The article discusses the issues of improving the coupon system for monitoring compliance with labor safety by establishing the level of labor protection at work and ranking the violations committed by departments and the enterprise as a whole. A modernized structure of the labor protection management system has been developed and a coupon control system has been proposed, integrated with three-level monitoring of the conditions and labor protection, which takes into account the magnitude of the coefficient of labor protection.

In this article considered information about contact and non-contact automation. In most cases, contact automation is used in many pumping stations. These phenomena are a power surge or voltage drop. And also the use of contact automation occupies a large place and inconvenience in operation. Non- contactless automation solves these problems. Pumping stations are usually designed with the calculation of their operation without permanent duty personnel. At large stations, a small staff is provided, which primarily carries out control functions. Set the automatic operation of pumping units. Often, automatic selection of switched-on units is carried out, reserve is withdrawn, station …
