The Stability

In order to explore the changes that autonomous vehicles would bring to the current traffic system, we analyze the car-following behavior of different traffic scenarios based on an anti-collision theory and establish a traffic flow model with an arbitrary proportion (p) of autonomous vehicles. Using calculus and difference methods, a speed transformation model is established which could make the autonomous/human-driven vehicles maintain synchronized speed changes. Based on multi-hydrodynamic theory, a mixed traffic flow model capable of numerical calculation is established to predict the changes in traffic flow under different proportions of autonomous vehicles, then obtain the redistribution characteristics of traffic flow. Results show that the reaction time of autonomous vehicles has a decisive influence on traffic capacity; the q-k curve for mixed human/autonomous traffic remains in the region between the q-k curves for 100% human and 100% autonomous traffic; the participation of autonomous vehicles won’t bring essential changes to road traffic parameters; the speed-following transformation model minimizes the safety distance and provides a reference for the bottom program design of autonomous vehicles. In general, the research could not only optimize the stability of transportation system operation but also save road resources.

Navigational System

Navigational service is one of the most essential dependency towards any transport system and at present, there are various revolutionary approaches that has contributed towards its improvement. This paper has reviewed the global positioning system (GPS) and computer vision based navigational system and found that there is a large gap between the actual demand of navigation and what currently exists. Therefore, the proposed study discusses about a novel framework of an autonomous navigation system that uses GPS as well as computer vision considering the case study of futuristic road traffic system. An analytical model is built up where the geo-referenced data from GPS is integrated with the signals captured from the visual sensors are considered to implement this concept. The simulated outcome of the study shows that proposed study offers enhanced accuracy as well as faster processing in contrast to existing approaches.

Abstract This paper presents reconfigurable hardware architecture for smart road traffic system based on Field Programmable Gate Array (FPGA). The design can be reconfigured for different timing of the traffic signals according to the received and collected data read by the different sensors on the road; the design has been described using VHDL (VHSIC Hardware Description Language). The SRTM (Smart Road Traffic Management) System has some more features that help passenger to avoid traffic jamming by sending the collected information through web/mobile applications to find the best road between the start and destination points, which will be displayed on Google maps, at the same time it will also shows the points of traffic jamming on Google maps. SRTM system can also manage emergency vehicles such as ambulance and fire fighter and also can send snapshots and video streaming for different roads and junctions to show the points of traffic jamming. The design has been simulated and tested using ModelSim PE student edition 10.4. Spartan 3 FPGA starter kit from Xilinx has been used for implementing and testing the design in a hardware level.

We find a simple, partially altruistic mechanism that can increase global gain for a community of selfish agents. The mechanism is implied in the phenomena found in the minority game. We apply the mechanism to a two-road traffic system to maximise traffic flow.

Formulation of the problem. At present, in the conditions of the development of trade, international transportation is becoming more significant. However, despite this, insurance of civil liability to the customs authorities with the use of the International Road Transport Book in the Republic of Belarus shows a negative trend. The purpose of the research is to explore the features of civil liability insurance to customs authorities using the International Road Transport booklet in the Republic of Belarus and analyze its dynamics, as well as to identify possible trends in its development. The object of the research is the features and practical procedures for voluntary insurance of civil liability to customs authorities using the book of International road traffic in the Republic of Belarus. Methods used of the research. The use of the induction method allowed us to designate ways to improve the procedures for voluntary insurance of civil liability to the customs authorities. The hypothesis of the research. The negative tendency of civil liability insurance to customs authorities is partly related to restrictive conditions, under which the carriage of goods under the International Road Traffic System can be carried out. The statement of basic materials. The Convention on International Road Transport defines the carriage of goods carried without intermediate transshipment in road vehicles, their compositions or containers, crossing one or more borders, from the customs of departure to the customs of destination, provided that a certain part of the International Road Transport operation between its beginning and end is made by road. Goods transported in accordance with the International Road Transport Procedure are exempt not only from paying or depositing in the intermediate tariffs of import and export duties and taxes, but also from customs inspection in them. Originality and practical significance of the research. The procedure for the operation of civil liability insurance to customs authorities with the use of the International Road Transport booklet, taking into account the UN Customs Convention on the International Carriage of Goods, is disclosed. Conclusions of the research. Insurance organizations of the Republic of Belarus increase the demand for insurance of civil liability to the customs authorities using the book of International road traffic and popularize it among residents of the country. This will contribute to the development of not only the insurance market in the country, but also the maintenance of the status of the Republic of Belarus as an export-oriented country.
