Most information and communication technologies systems providing some form of intelligence to future smart cities will more or less use data-based predictive models. Since the amount of data collected increases rapidly, it is becoming crucial to select proper data that are relevant and useful for the specific predictive model. The importance and usefulness of two wrapper feature selection methods is demonstrated here on 23 time series appearing typically in smart city area. Particularly, high dimensionality reduction is achieved without sacrificing the prediction performance for energy consumption, temperature, price and people's presence prediction. Only for thermal discomfort prediction, high dimensionality reduction causes small increase of mean average prediction error typically less than 1%. Since the two methods are comparable from the dimensionality reduction and prediction performance point of view, sensitivity based pruning is recommended, because of its less computational demands.

Efficient and environmentally friendly management of mobility plays a significant role in the smart cities. As the transportation systems and the information systems link the components, their development is essential for realization of complex city operational schemes. Information is one of the most important inputs for the activities, especially in transportation. Logical and physical integration of transportation information systems and services are required by the increasing expectation of travellers and became possible by the development of the info-communication technology. Since the results of comprehensive system and process-oriented scientific research on this area are slightly published, the devised analysis and modelling methods described here and their adaptation fill this niche. Herewith the architecture of the entire integrated system and the model of the intelligent traveller with the personalized mobile application have been presented in more details, but the method is applicable for each subsystem with different resolutions. The results are of great importance contributing to the success of the top-down systems engineering.

The term Smart Cities is used in many different meanings ranging from ITC infrastructure development to soft-factor-based approaches and “creative cities”. This paper interprets smart cities as an approach to the problem-solving based on deliberative complexity management. This enables both to increase the range of tools available to Smart City approach and to use the large body of complexity and sustainability related research literature with broad range of historic case studies.

This paper presents the result of the project TA02031411 - transportation system which provides information about the predicted occupancy of parking spaces to truck drivers. Providing this information leads to optimizing the use of existing parking spaces on the highway network and also makes it easier for drivers to deciding on a suitable location for parking, which ultimately contributes to the fluency and safety of traffic.

The paper deals with safety improvement of facilities of critical infrastructure in the railway domain based on integral safety management. It means that it solves not only secure facility but also safe facility that is the facility which at itself critical conditions do not endanger either itself or its vicinity, i.e. humans and other public assets. In the modern practice of safety management and safety engineering there are introduced new procedures like All-Hazards-Approach, Defense-In-Depth and for construction of critical facility safety there is used the five-layer model of safety management. The article comprises current state of appropriate railway system with ideal case based on mentioned concept and gives proposal of measures for improving the safety of followed critical facilities.

The paper presents urban traffic control method suitable and tested for a small urban areas enabling more fluent traffic and thus increasing the throughput of the controlled area. The model is implemented in the adaptive Traffic Dependent Control module for higher control of the area designed for the optimization of the intersection signal plans, providing the best improvements for intersections with irregular traffic.

In this paper we discuss the paradigm shift that has to be understood by the decision makers as well as societies in the field of transportation. It is not sufficient to focus only on mobility as the current strategies do, but we need to look at citizens quality of life as whole. It is affected through different aspects, and only one of them is transportation. We need to provide a better way to participate in activities - increase accessibility of goods and services. This cannot be done with look at transportation only. We need to understand the entire organism of a city. This has been recently understood by the Smart cities initiative. A smart city is defined within this paper as an alliance system, i.e. a system where particular subsystems use the common resources in a synergic way. In order to make this concept work, an objective function following the above mentioned principles must be provided. In this paper, we offer entropy of a city as a promising candidate for such objective function.

Courier, express and parcel (CEP) transports have been growing significantly. CEP is one of the biggest segments in urban freight transport. It does not only contribute to the wealth of our cities, but also comes with negative impacts such as noise, congestion and pollution. Transport policy has developed measures to reduce these negative impacts. This paper proposes a conceptual framework to analyze smart policy options. It focuses on the derivation of CEP demand and supply.

The forecast (world bank) related to the growth of world population tends to be around 9000 million to 2050 and most of the people will live in the cities or in conurbations, this means that, a new approach for support the development of the cities needs to be analyzed. Currently, the mankind has developed and produce a lot of technology advances and many of them are related to the Information and communications technology (ICT). In this way, ICT has become in a key element for the development of the cities, even, introduce the ICT concept in the context of the cities has provoked a new scope for the cities that is called Smart City or Digital City. In this paper, it is presented an approach for Colombian Smart Cities where have been taking in to account several experiences of deployments of solutions in the field of Intelligent Transportation Systems (ITS) taking these, like a core for several solutions for the inhabitants, in addition, government organization is presented like a key element for deploy solutions in the context of Colombian Cities where the ICT solutions can be applied.
