New applications of a fuzzy expert system (FES) for direct control of traffic lights in the areas of locks and one-way sections on inland waterways are presented. FES implements the knowledge of experts in the field of water transport on a controller. FES-SL (application in ship locks) was created for a single-chamber two-way ship lock. The system...

This chapter aims to present the analysis and comparison of some well-known nature-inspired global optimization techniques applied to an expert system controlling a ship locking process. A ship lock zone represents a specific area on waterway, and control of the ship lockage process requires a comprehensive approach. The initially proposed Fuzzy Ex...

The number of accidents on rural roads still represents a higher percentage of accidents than those occurring on built-up areas and motorways. Many countries are working on the definition and implementation of strategies that relate to the improvement of traffic safety on rural roads. This paper presents an approach to the analysis of traffic safet...

This paper analyses the management process of the vessel traffic control on one-way section on navigable canal with the adaptive time-sequential filter (traffic lights). One-way section on canal significantly decreases waterway capacity and requests special attention in control and regulation of the vessel traffic. The vessel traffic is a stochasti...

A ship lock zone represents a specific area on waterway, and control of the ship lockage process requires a comprehensive approach. This research is a practical application of a Mamdani-type fuzzy inference system and particle swarm optimisation to control this process. It presents an optimisation process that adapts control logic to the desired cr...

Traffic safety policy defines plans that are expressed using numerical values for the planned level of improvement. The directing or apportioning of efforts represents the initial step of planned improvements. If a road is observed as a system of sections, the sections should be prioritized, selected, and investigated according to precise enhanceme...

Presented article outlines a rationale, why it is necessary to develop competence about infrastructure risk in water transport. Climate changes are evident and require special attention and global monitoring. Current risk assessment methods for Inland waterway transport just consider some dramatic events. We present a new method for the assessment...

One of the most common subject of driver's behavioral research was speeding behavior, which present one of the most frequent traffic offence and which is responsible for the occurrence of road accidents and their severity of consequences. Research have indicated at strong correlation between drivers' attitudes toward speeding, speeding behavior and...

This paper presents the comparison of some well-known global optimization techniques in optimization of an expert system controlling a ship locking process. The purpose of the comparison is to find the best algorithm for optimization of membership function parameters of fuzzy expert system for the ship lock control. Optimization was conducted in or...

Aim To evaluate clinical status of patients with chronic subdural hematoma (CSDH) on hospital admission and to predict their outcome after the neurosurgery treatment using Karnofsky index scale (KI). Methods Clinical and surgery data of patients with CSDH were collected prospectively. Fifty 50 adults aged over 41 with CSDH diagnosed and hospitalize...

One of the essential questions placed before a road authority is where to act first, i.e. which road sections should be treated in order to achieve the desired level of reliability of a particular road, while this is at the same time the subject of this research. The paper shows how the reliability reallocation theory can be applied in safety analy...

In the run toward leaner supply chain, organisations have opted for new business paradigms which assume a strict selection between core and non-core activity, cutting costs and reducing waste in every supply chain processes. A number of research and case studies shows that the cost savings from these initiatives were admirable. However, this busine...

This paper presents the development of a Decision Support System (DSS) for the management of ship locks that relies on fuzzy logic. It contains a brief overview of the history and the construction of locks and basic information related to fuzzy logic, fuzzy linguistic variables and methods used in approximate reasoning. In reality, ship lock contro...

Climate changes require special attention and global monitoring. Impacts on nature and industry are increasingly evident. Water transport could be the backbone of the future European combined transport system. Unfortunately, risks in water transport are perhaps an under researched area and consequently, this article outlines a rationale, why it is...

Water transport could be the backbone of the future European combined transport system. The development of the cargo transport in river traffic depends directly on technical-exploitative characteristics of the network of inland waterways. Research of navigational abilities of inland waterways always comes before building ships or making a transport...

Analysis of traffic accident frequency represents an important subject of research of many authors. From the aspect of temporal analysis of traffic accident occurrence, two approaches have been singled out in previous practice: the collective (analyzes traffic accidents over a longer period of time) and individual (analyzes traffic accidents in rea...

Being aware of the waterway capacity, as a substantial characteristic of each traffic way, has a great importance to authorities that perform control and regulation of the vessel traffic. In specific real conditions and situations, for the purpose of the vessel traffic control, it is necessary to know specified limits of traffic density, which depe...
