Fuzzy Logic in Traffic Engineering: A Review on Signal Control

Since 1965 when the fuzzy logic and fuzzy algebra were introduced by Lotfi Zadeh, the fuzzy theory successfully found its applications in the wide range of subject fields. This is mainly due to its ability to process various data, including vague or uncertain data, and provide results that are suitable for the decision making. This paper aims to provide comprehensive overview of literature on fuzzy control systems used for the management of the road traffic flow at road junctions. Several theoretical approaches from basic fuzzy models from the late 1970s to most recent combinations of real-time data with fuzzy inference system and genetic algorithms are mentioned and discussed throughout the paper. In most cases, fuzzy logic controllers provide considerable improvements in the efficiency of traffic junctions’ management.

User authentication system for testing students in computer sciences subjects

At CTU FTS we are currently developing BioTest, an authentication system for testing students using state-of-the-art information technology and unambiguous Biometric authentication for each user. We use this system for identification during exams and testing. The BioTest software operates on the basis of a students face recognition comparing the pattern with data on the students ID card, while informing the relevant teacher about the students identity.

Detection of persons in a vehicle using IR cameras and RFID technologies

A goal of this article consists in demonstrating the eCall system enhancement. We propose to enhance the system by next relevant information for emergency services - exact number of persons in a vehicle including recognising adults and children, number of disabled persons and their disability kind. Further, the system will enable to identify a driver.

Improvement of safety of buildings for handicapped persons: Public buildings and constructions (tunnels, bridges etc.)

Safety in public buildings is obtained by technical means employed in hazardous situations (accident, fire etc.). In case of an emergency, endangered premises can be evacuated by emergency exits, while the monitoring center monitors the situation and activates the pre-prepared contingency plans to enable safe (managed) evacuation. Special attention needs to be paid to the handicapped persons. Their impediments (blindness, restricted movement etc.) pose extra challenge, when in the ensuing chaos or panic they try to find emergency or barrier-free exits. This article describes a proposal for expansion of the existing evacuation systems by elements of localization of the handicapped persons in buildings. The aim is to provide this information to the rescue teams and thus improve the evacuation capacities for the handicapped.

Parking Management Control System for smart cities

Concurrently, depending on increasing number of vehicles in cities, importance of incentive car-parks on peripheries, parking houses within shopping centres, airports, etc. constantly arises. At the same time, also demands on intelligent control such of these car-parks arise by reason of effective use of every parking spot. The proposed Parking Management Control System (PMCS) provides overview not only from the point of number of free spots but also number of spots intended for parents with children, handicapped persons, or XXL vehicles. In case, the vehicle is identified as one with permanently disabled persons, parents with children, or XXL vehicle then PMCS purposefully navigates this vehicle to a dedicated spot. During the certain time, the system knows actual positions of every vehicle, time spent on a car-parks, and its type.

Fuzzy Algorithm for Highway Speed Harmonisation in VISSIM

In this paper is demonstrated, how a fuzzy control system can be implemented and verified directly in a microsimulation tool from the company PTV, VISSIM. A new fuzzy algorithm for speed harmonisation is developed and its implementation is explained in details. The main advantage of this solution is in the direct implementation of the control algorithm in the microsimulation tool without the need to deal with an API and external software. Additionally, the configuration and optimisation of the control algorithm is performed quickly in the tool and directly responds to the microsimulation results. This has an impact on the time to implement such a solution as well as the overall cost, since a single resource able to work with the microsimulation tool can do the work and no programming experience are required.
