Nowadays, when new technologies are being developed and people are looking for smart solutions, the field of automation and digitization grows faster and faster. The demand on the telecommunications is increasing in economy, healthcare as well as in the transportation. The transportation systems are facing the challenge of smart infrastructure, autonomous vehicles, and its connectivity. The requirements for these systems lie mainly in safety, interoperability and sustainability, especially in the area of cooperative transport systems (C-ITS).This article focuses on a possible approach to test and evaluate C-ITS, threats that have to be ruled out in future, possibilities to ensure connectivity among the vehicles and infrastructure in C-ITS.For these purposes, Czech Technical University in Prague (CTU) and its laboratory Certilab develop special procedures based mainly on the C-ITS SIM tool. This tool ensures validation and verification of C-ITS messages and its interoperability among all equipment. This paper also reviews the already developed applications and proposal of the functionalities that should be implemented for the testing as well as the examples of real usage of the developed tool in testing the communication of C-ITS messages.

the paper explains the essence of creating a historical traffic model and its application in the actual development of mobility and intelligent transport systems in cities. It focuses on the process of creating and maintaining such a model and presents the method of its construction. The developed method is demonstrated on a practical example from the city of Prague based on data from section detectors, including examples from the model calibration process. The purpose of the paper is to convey a broader awareness of how to easily and effectively capture the amount of traffic data that we often have today, and use it to benefit the functioning of traffic and cities.

Automatic parking services can make a significant contribution to saving time, reducing emissions, increasing safety and increasing the mental well-being of drivers. Thanks to automated parking, it is also possible to optimize the use of parking spaces.The article deals with the issue of automated parking in urban areas. The aim is to present a proposal for the application of smart solutions in the form of a Mobility Hub for parking, along with subsequent control and enforcement that falls within the areas within Smart City. Mobility Hub is an important attribute for the future functioning of mobility. An integral part of the verification of parking options is the users' own interest in automatic elements in the vehicle and thus the connection to mobile applications, other systems, and involvement in the Mobility Hub for the use and sharing of information. The survey, the results of which are reflected in this article, examines the interest of potential users.

Data analysis is very important tool for acquiring information about object of our interest. It involves a lot of various methods, mainly from the area of data mining or statistical analysis. However, most of these methods aim at continuous data. In real applications, especially in the field of Smart Cities, questionnaires are a frequent source of data. They are mainly a source of discrete data. As commonly used data analysis methods, such as regression analysis, naturally work with continuous data, complications can occur. However, the linear regression analysis can be carefully used to to analyze discrete data, but carefully.The paper wants to give a warning before a direct mindless use of regression analysis for discrete data, especially when the independent variables are nominal. Also some ways how to modify values of the independent variables to achieve sensible results with linear regression applied to measured discrete data from the Smart City area are sketched.

Electric powered motorbikes nowadays rapidly increase ratio across micro-mobility shared services. This trend is in addition supported with smart city development. The electric powered bikes bring specifics for the riders in sense of motorcycle control. Electric powertrain has different complex features that rider has to deal with and it is not primarily trained for. Current research typically copes with challenges such as route planning, travel range, daily recharging etc. Therefore, the research deals not only with external characteristics, but also with internal factors which can be affected by rider. This article aims to the specifics of riding the electric motorcycle compared to the conventional petrol powertrain. It is important to define crucial parameter trends to follow these specifics to increase safety of users and thus the traffic safety in the smart cities.

This article deals with describing the key parameters of regional public transport demand in the Lovosice Area, Czech Republic. It specifically deals with the issue of daily variation, the ratio of transport demand in peak and off-peak hours and the modal ratio.The second part presents the demand characteristics collected in the Lovosice area. Among these, a daily variation of the suburban bus and train line is analyzed and compared. This analysis is followed by recommendations for vehicle optimization based on the highest peak hour occupancy. In addition, the system split of the parallel routed regional public transport modes with its influencing factors on demand distribution is discussed.

The paper deals with the research of public transport and proposes a new dynamic model of public transport service. The paper describes the problematic points in the service area, divides the territory and the transport lines on it. At the same time, it brings a new perspective on transport service and describes the necessary modifications to make the new proposed transport system feasible into real operation. It is assumed that the output will be a relevant basis for the actual implementation in real operation.

Modern telematics systems are based on data collected from real operation. The article works with a new source of traffic data, which is freely available to the public. Linking traffic data with spatio-temporal significance also allows us to examine data from the perspective of user behavior. From the principle of data collection, the data already have their specific assumed behaviors, which are described in the article. It is desirable to further investigate these behaviors, to what extent they are affected and whether they can be considered as parameters of the entire traffic flow.

In this paper, the concept of Smart Parking Garage (SPG) is formally introduced. The SPG is a garage that makes use of sensors, dynamic message signs, smartphone applications, and a computer server connected to form a smart system. The concept of operations, including functional requirements, equipment, relationships with the U.S. National Intelligent Transportation Systems (ITS) architecture, and a typical use case of an SPG are described. To assess the benefit of an SPG compared to a conventional garage, a five-level garage was selected, and the search times to park in 22 selected spaces were measured by a test vehicle. The results showed that SPG reduced the median search time by 35 seconds. The level of service improved from an approximately equal split of As and Bs to all As. The economic benefit of SPG is also illustrated through an example.

Recently, an increasing number of battery electric railway vehicles are being put into service. The operational characteristics of hybrid-powered vehicles are different from diesel propulsion, which is a challenge for railway companies. This paper introduces a multi-criteria evaluation method to facilitate the harmonization of various parameters related to hybrid vehicles and the evaluation of railway lines based on the attributes of new types of railcars. The length of the non-electrified sections, battery capacity, condition of railway tracks, number of operated railcars, and passenger traffic volume were identified as the main attributes that influence the applicability of battery electric railcars. It was found that without charging station deployment, railway lines electrified in 40-60% are the most suitable for battery electric railcar operation.
