Efficient traffic control and management is a fundamental and urgent challenge in our ever-growing cities. Maximizing roadway capacity usage, balancing traffic flows, decreasing emission, improving traffic safety and providing motorists with the best end-to-end transportation experience are the most important goals of modern intelligent traffic control infrastructures. Evolving traffic light or traffic signal controller systems are playing an important role in these architectures by adaptively and dynamically coordinating individual traffic lights to achieve city-wide objectives of traffic operations. The integration of such systems with vehicle-to-vehicle (V2V) and vehicle-to- infrastructure (V2I) communication techniques (together referred as V2X) could easily be the next step of this evolution allowing for dynamic real-time information exchange between all the players of the traffic controlling ecosystem and fostering cooperative urban mobility. In this paper we propose a possible architecture for a V2X-integrated traffic light controller systems and present the testbed with our proof-of-concept implementation of the proposed scheme.

We introduce a sensor-aided predictive algorithm for Doppler-shift estimation and compensation in dynamic vehicular environments. The proposed concept uses sensor data to improve adaptation of V2V communication parameters to instantaneous channel states. The obtained results show that the use of vehicles' sensor data enables a range of improvements in direct vehicle-to-vehicle communications.

This paper focuses on a channel testing scheme based on public LTE network for high-speed scenario. To simplify the deployment of channel testing for high-speed scenario, public LTE CRS in downlink can be utilized so that setting up a transmitter is avoided. A receiver system was designed and the testing was carried out on a high-speed train. Before the field testing a verification for receiver via radio communication tester and channel simulator was done. The result are helpful for the receiver design.

In its initial part, the paper presents an overview of popular technologies and systems currently developed or employed in maritime communication. These solutions are used to provide both ship-to-ship and ship-to-shore communication for the purpose of supporting specific services, often dedicated to maritime safety and e-navigation. Utility of such communication systems have been thoroughly verified over the years and their strengths and limitations are also widely known. The later include relatively low maximum throughput and/or high cost of both deployment and operation, caused by the requirement of long communication range and high reliability in difficult propagation conditions. Based on the above overview, the subsequent part of the paper presents preliminary results of research conducted at the Computer Communications Department, Faculty of Electronics, Telecommunications and Informatics, Gdansk University of Technology within the netBaltic project. The project's objective is to create a maritime communication system, able to transparently utilize various transmission technologies to form a multihop network structure and thus provide maritime vessels with Internet Protocol-based communication capabilities in diverse set of conditions and areas. For this purpose a combination of mobility management, mesh and delay tolerant network mechanisms is employed, allowing deployment of a wide range of user-level services, starting with general purpose Internet access, through navigation/weather charts distribution and ending with varied e-navigation functionalities.

Given the increasing interest for future connected vehicles, the long term evolution (LTE) specifications are being enhanced by 3GPP to cope with the vehicle-to-everything (V2X) scenarios starting from the upcoming Release 14, which will include, among others, vehicle-to-vehicle (V2V) direct communications. Since the main service expected for connected vehicles is the cooperative awareness, in this work we aim at deriving the number of neighbors that can be managed by LTE-V2V. In addition to the normal half duplex (HD) radios, which strictly limit the granularity of resource allocation, advanced full duplex (FD) radios are also considered. Results show that LTE-V2V with HD radios is able to manage up to few tens of neighbors, whereas FD can increase this limit significantly at the expense of an increase of complexity.

Vehicular communications can be achieved through the infrastructure (Vehicle-to-infrastructure network, V2I), as well as directly through vehicle-to-vehicle communication (V2V) via ad hoc networks. In V2V communications, the routing protocols are designed in order to optimize the dissemination of messages. This paper presents an evaluation of routing protocols such as the Optimized Link State Routing (OLSR), Ad hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR), and Geographic Routing Protocol (GRP), while considering both vehicular safety application requirements and mobility models based on real-world traces of vehicular traffic. The results show that, though proactive routing protocols perform better in this context, the four routing protocols fail to fulfill the safety application requirements on the delay metric even for a reasonable number of vehicles.

We are developing a Pedestrian-Vehicular Collision Avoidance Support System (P-VCASS) in order to protect pedestrians from traffic accidents with vehicles. P-VCASS is a system that makes observations of pedestrian's moving situations. Drivers of neighboring vehicles are given warnings in advance if there is a possibility of collision between vehicles and pedestrians. Pedestrians moving around in an intersection are dangerous for vehicle drivers because they may run out into the road suddenly. So we have to estimate their dangerous action. We propose a new estimation method of pedestrian's actions at an intersection by using pressure sensors and moving records in this paper. We show the effectiveness of the proposed system by experiments using a vehicle and a pedestrian with a terminal in an intersection. As a result, we show that a driver of vehicle is able to recognize dangerous pedestrians quickly and accurately.

This paper shows the strategy and results of the simulation of the Train integrity determination system into the on-board ETCS. It first shows the Smart Train Positioning System (STPS), a GNSS based on-board system that determines the the train integrity. Then, scenarios are derived for two different routes. After that, the test setup based on the ETCS on-board unit virtual laboratory is explained. Finally, the results show that the on-board ETCS equipment is able to detect correctly the integrity loss and operates accordingly. Then, the capability of STPS of providing integrity information is proven and that leads to the conclusion that train's integrity can be determined on-board by using STPS.

An Outdoor-to-Indoor (O2I) wireless link allows obtaining information from devices located outside a train. This is the case for devices installed on the roof that need to be monitored wirelessly by data-collecting devices located inside the train. In these situations, the electromagnetic signal is diffracted around the structure of the train and reflects on the environment or goes into the car through the windows. This creates a non-line-of-sight channel which is strongly dependent on the physical structure of the train, its materials, and the surrounding environment. In this work, the O2I channel of a metro car is characterized at 2.6 GHz. Narrowband channel measurements are carried out in station, tunnel and open field environments, and obtained results are modeled and discussed.
