Kentucky Transportation Center Research Report
Executive Summary and Introduction
This report documents an analysis of traffic crash data in Kentucky. A primary objective of this study was to determine average crash statistics for Kentucky highways. Where used, rates were calculated for various types of highways and for counties and cities. Difference criteria were used for exposure.
Average and critical numbers, SPFs, and rates of crashes were calculated for various types of highways in rural and urban areas. These use crashes identified on highways where Annual Average Daily Traffic (AADT) volumes were available. The data in this report may be used to help identify problem areas. …

Increasing The Train Safety Level Based On A Process Approach, A.Kh. Makhkamov, M.Sh. Valiev
Journal of Tashkent Institute of Railway Engineers
The article deals with improving the level of train traffic safety based on the process approach, provides a classification of failures of technical means and methods of their parry. The main attention is paid to the occurrence of cases of traffic safety violations. To increase the level of the DB support system, the entire process of organizing transportation is divided into four main blocks: management processes, resource support processes, production processes, interaction and control processes.

Journal of System Simulation
Abstract: Lane restriction strategy for trucks is an effective way to improve the capacity of expressways and ease traffic congestion. Microscopic simulation models were employed to assess the impacts of restriction strategies and truck accidents on expressway traffic condition. Parameters were calibrated and validated based on the field data of Jingzang Expressway. Five simulation scenarios with different time setting for trucks' no passing were established, and evacuation after truck accident was simulated. Simulation results indicate that the most suitable time for trucks' no passing is from 7:00 to 19:00. The travel time of small passenger cars can be reduced …
