Opis:: A protocol, called common driving notification protocol (CDNP), is proposed based on the classified driving behavior for intelligent autonomous vehicles, and it defines a standard with common messages and format for vehicles. The common standard format and definitions of CDNP packet make the autonomous vehicles have a common language to exchange more detail driving decision information of various driving situations, decrease the identification time for one vehicle to identify the driving decisions of other vehicles before or after those driving decisions are performed. The simulation tools, including NS- 3 and SUMO, are used to simulate the wireless data packet transmission and the vehicle mobility; the experiment results present that the proposed protocol, CDNP, can increase the reaction preparing time with maximum value 250 seconds, decrease the identification time and the average travel time. Prospectively, it is decided to implement the CDNP as a protocol stack in the Linux kernel to provide the basic protocol capability for real world transmission testing.

Opis:: This paper presents many varied mobile platform suited for different kinds unmanned ground vehicles applications. The Unmanned Ground Vehicle's platform is the glue that holds together all the other aspects ofafield able tactical military unmanned ground vehicle. Unless the platform exhibits a high degree of mobility and outstanding ruggedness it will fail to achieve its target location. If the UGV can not deploy its sensor s at the correct location then the mission is rendered useless. The platform should merge the drive system, a power supply system sufficient for the required mission period, an advanced communication system capable of returning real-time information to the user and a user friendly Human machine Interface that allows long term, stress free operations. The platform must have a very high immunity to electro-magnetic interference, and logistically any tactical UGV must not impose a heavy load on available systems or manpower. Unmanned Ground Vehicle technology areas, platforms for reconnaissance, surveillance and EOD missions, the first dedicated IED disposat robotic platform "Wheelbarrow", remotely controlled French tank (AMX30B2) for mine clearance operations, All terrain vehicle Gamma Goat, schematic of typical hybrid electric power train for UGVs, AHED 8x8 Phantom view revealing power and propulsion are presented in the paper.

Opis:: One of the applications of Unmanned Ground Vehicles (UGV) consists in conducting tasks connected to removing and disposing of Improvised Explosive Devices (IED). The tasks are often performed in hard to reach places, on off-road terrain, with weights and dimensions of explosives which require the use of work attachments of considerable lifting capacities. Due to this, it is necessary to equip the robot with suspension designed for performing such tasks. Because of variable character of the charges which are subjected to the chassis of robots, it is necessary to build a suspension with variable characteristics and examine efficiency of its action. One of the research methods that can be used for that purpose are the simulations based on the method of Multibody Systems. The paper presents a hydro-pneumatic suspension system of an EOD robot, which has been developed at the Military University of Technology, describes its model, simulation findings and the initial verification thereof based on a real object. Apart from that, special consideration is given to the quality and effectiveness of UGV suspension systems. The development of a basic platform enables the use of the platform for various purposes as a carrier of a multi-sensor system for detecting dangerous materials or for carrying other attachments.

Opis:: Contemporary and future battlefield may be characterized by a great dynamism of action in both defensive and offensive operations. It is possible, that armoured and mechanized troops, acting at first attack, will suffer from shortages of supplies of materials and other equipment, especially propellants. It concerns particularly a fuel to engines of driving vehicles. Therefore in many cases for engine powering (as multi-propellant engines or adapted to work on substitute fuels) may be used substitute fuel. The fuel parameters sometimes may be much different from parameters of diesel. So it is substantially important to estimate their dynamics during the planning stage of combat missions. Paper includes attempt to estimate dynamic features of the combat vehicles using substitute propellants. Applying substitute propellants leads to reducing the power of the engine up to 10 % comparing to diesel. It has essential impact on lowering the dynamic ratio at similar level. That leads to lower maximum drive speed at given resistance ofmotion and reducing the ability to climb slopes. There also appears deterioration of spurt, extending the time of reaching speeds at about 17%. Paper shows results of traction calculations of combat vehicles and the influence of powering them with renewable fuel on their effectiveness.

Opis:: Transformer efficiency and regulation, are to be maintained at maximum and minimum respectively by optimal loading, control, and compensation. Charging of electric vehicles at random charging stations will result in uncertain loading on the distribution transformer. The efficiency reduces and regulation increases as a consequence of this loading. In this work, a novel optimization strategy is proposed to map electric vehicles to a charging station, that is optimal with respect to the physical distance, traveling time, charging cost, the effect on transformer efficiency and regulation. Consumer and utility factors are considered for mapping electric vehicles to charging stations. An Internet of Things platform is used to fetch the dynamic location of electric vehicles. The dynamic locations are fed to a binary optimization problem to find an optimal routing table that maps electric vehicles to a charging station. A comparative study is carried out, with and without optimization, to validate the proposed methodology.

Opis:: This article highlights the need to rethink how to manage mobility in Morocco more intelligently, given that it is a major pillar of economic competitiveness. Smart mobility based on Intelligent Transport Systems (ITS) allows to improve and ensure the optimal use of existing infrastructure before embarking on heavy and irreversible infrastructure projects. The case regarding the separation of the urban traffic and the Heavy Goods Vehicles (HGV) traffic circulating between Casablanca Port and Zenata Dry Port is a relevant example where smart mobility could provide efficient solutions without building costly tunnels. A dynamic simulation was made using the Aimsun software to quantify the relevance of the proposed lane designated to HGV in the existing road. This simulation allows to visualise congestion sections and quantify the circulation of vehicles and pedestrians. The article presents defined functions and characteristics of the Advanced Traffic Management (ATM) to ensure the optimal operation and efficient setting of the simulation. All appliances, hardware, and sensors that will be set up on-site will help to improve traffic safety, traffic flow, traffic information, and reduce congestion and pollution. This case study illustrates the complexity of managing the flow of goods in cities and suggests how to solve this type of problems using smart mobility. This research proposes reserving a special lane for HGV. ITS will help this cost-optimal alternative, will promote the urban framework of the coastal road, and contribute to sustainable mobility in Casablanca.

Opis:: Discussions on how urban space would be transformed by the use of autonomous vehicles (AVs) are scarce. This study identifies the impacts caused by the shared use of AVs on urban parking and urban space management. An estimation method was formulated considering the reduction in parking demand, the possible alteration in vehicle ownership, and the reallocation of urban space. A case study was performed in a 673,220 m2 area through scenarios created by using real data of parking spaces and the results of previous studies. Results showed that parking spaces can be saved with the use of shared AVs, which would allow the reallocation of urban space to new uses (for example, implementation of around 12,000 bike-sharing docking spots, 10 km bike lanes, 7 km additional traffic lane or 140 ‘parklets’). The results contribute to revealing the positive impacts of AVs.

Opis:: The article concerns the analysis of trends and policies supporting the development of zero-emission mobility, in accordance with the assumptions of the European Green Deal. The aim of the study is to identify and assess the essential factors determining the level of sustainability of the electromobility system in relation to individual car transport in the European Union. he article reviews strategies for the development of climate-neutral mobility as outlined in strategic documents, the European Green Deal and the “Fit for 55” package. The current state of development of the electric vehicle market and charging infrastructure is shown, which implies a number of challenges in the pursuit of emission-free mobility. A review of the literature on the subject and the results of the expert analysis confirmed the importance of national and regional policies in the uptake of electric vehicles. Taking active measures to increase the level of sustainability of the electromobility system should first focus on the further development of charging infrastructure, the creation of an EV battery value chain and the uptake of cars. The main expectations for the development of electromobility are to reduce CO2 emissions, reduce dependence on the supply of fossil fuels, increase the competitiveness and innovation of the economy, and reduce the social costs generated by transportation.
