Mathematical application for departure model

In the light of todays high traffic volume, it is crucial to anticipate the traffic flow on traffic lights controlled intersections. Without this knowledge, it would be impossible to control the traffic in complicated hubs, such as, for instance, those in Prague. One of the characteristics, through which we can describe dynamics of vehicle movement on traffic lights controlled intersections, is the interval between departure of a vehicle from the space in front of the stop line and the arrival to the actual stop line. This is called a departure model. Our aim is, first, to create an appropriate mathematical application, which would take into account individual variables influencing departure of individual vehicles and determine the dependence among these variables. Second to create such a departure model, which would, on one hand, correspond as much as possible to the contemporary traffic situations, but on the other hand, be more exact for specific intersections.

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.

People counting by means of Wi-Fi

People counting (detection) in public transport setting provides highly valuable information for transport lines planning in respect of their density, routes, timetables and vehicle occupancy. The real-time information on current number of passengers at given point enables the city councils together with the carriers to make significant improvements in line planning and resource use efficiency. Thus it allows lowering of their costs.

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.

Service quality of train system for visually impaired passengers

An integral part of the concept of “smart cities” are information and orientation systems for visually impaired persons. This paper presents the results of the research of functionality trains system for visually impaired passengers in the Prague.
