Traffic Demand

The trend of increasing traffic demand is causing congestion on existing urban roads, including urban motorways, resulting in a decrease in Level of Service (LoS) and safety, and an increase in fuel consumption. Lack of space and non-compliance with cities’ sustainable urban plans prevent the expansion of new transport infrastructure in some urban areas. To alleviate the aforementioned problems, appropriate solutions come from the domain of Intelligent Transportation Systems by implementing traffic control services. Those services include Variable Speed Limit (VSL) and Ramp Metering (RM) for urban motorways. VSL reduces the speed of incoming vehicles to a bottleneck area, and RM limits the inflow through on-ramps. In addition, with the increasing development of Autonomous Vehicles (AVs) and Connected AVs (CAVs), new opportunities for traffic control are emerging. VSL and RM can reduce traffic congestion on urban motorways, especially so in the case of mixed traffic flows where AVs and CAVs can fully comply with the control system output. Currently, there is no existing overview of control algorithms and applications for VSL and RM in mixed traffic flows. Therefore, we present a comprehensive survey of VSL and RM control algorithms including the most recent reinforcement learning-based approaches. Best practices for mixed traffic flow control are summarized and new viewpoints and future research directions are presented, including an overview of the currently open research questions.

Use Of Social Media

Over recent years, there has been a growth of interest in the use of social media including Facebook and Twitter by the authorities to share and updates current information to the general public. The technology has been used for a variety of purposes including traffic control and transportation planning. There is a concern that the use of new technologies, including social media will lead to data abundance that requires effective operational resources to interpret the big data. This paper proposes a tweet data extractor to extract the traffic tweet by the authority and visualise the reports and mash up on top of online map, namely Twitter map. Visualisation of traffic tweet on a map could assist a user to effectively interpret the text based Twitter report by a location based map viewer. Hence, it could ease the process of planning itinerary by the road users.

Reducing car dependency requires orchestrated multi-sectoral, multi-policy action in a complex landscape. Thus, development of proposed interventions to reduce car dependency should be informed by systems thinking, complexity science, and socio-technical transition theory. We aim to co-design sustainable systems-oriented intervention approaches to reduce car dependency in Belfast. The study includes seven integrated tasks—1: Map stakeholders and partnerships influencing car dependency using stakeholder network analysis; 2: A review of systematic reviews regarding interventions to reduce car dependency; 3: Map-related policies via analysis of policy documents and semi-structured interviews; 4: A participatory group model building workshop to co-produce a shared understanding of the complex system perpetuating car dependency and a transition vision; 5: Using Discrete Choice Experiments, survey road users to evaluate the importance of transport infrastructure attributes on car dependency and on alternative modes of travel; 6: Citizen juries will ‘sense-check’ possible actions; and, 7: Stakeholders will interpret the findings, plan orchestrated multi-sectoral action, and agree on ways to sustain collaborations towards the common vision of reducing car dependency. We expect to attain a systemic view of the car dependency issue, potential intervention approaches to reduce it, and a framework for their integration through the co-ordination of stakeholder actions.

Negative Impacts

Abstract Traffic infrastructure localities with temporal restrictions for example due to reconstructions, or modernization, are important aspects influencing the traffic safety and traffic flow. On the basis of our research, we can identify main factors, which generate travel time loses, and which often cause traffic accidents in bottlenecks. First of all, it is improper late merge, speeding, tailgating, lower tolerance and consideration to other road users. Nervousness and ignorance of drivers also play an important role in generation of traffic congestions, lower level of service and resulting external economic loses. One of the tools eliminating the traffic restriction negative impacts is usage of portable telematics systems. In 2011 to 2013,project ViaZONE was in progress, which was to design an intelligent system with the aim to eliminate the mentioned risks and reduce economic losses generated by traffic congestions. Using available data and information, we have proved profitability and cost-effectiveness of dynamic systems for traffic control of work zones. Regarding traffic management, the system showed some problems due to indisciplined drivers and the system proved that speeding in these hazardous road segments is a common practice which caused accidents and congestions.

Traffic Simulations

Operational behavior models are used in traffic simulations to represent the subconscious, short-termdecisions made by road users to respond to other road users, the infrastructure and traffic control measures. Calibration and validation of these models can be achieved using observed trajectory data from real road users. For lane bound traffic, it is assumed that road users intend to follow a given lane with a certain desired speed across the intersection. Any deviation from this planned path is in response to other road users or the environment. It is difficult, however, to identify and separate the desired movement of more flexible road users that do not follow lane disciple, such as bicyclists, from movements made as a reaction to other road users or obstacles. This can lead to poor calibration of operational behavior models and unrealistic behavior in the simulation. Tactical behavior models recreate the conscious decisions made on a time horizon of seconds to minutes to cope with the immediate traffic situation. As such, tactical behavior models are responsible for selecting the planned path across an intersection.Here, SUMO is coupled with the simulation software DYNA4 to create a simulated road environment for a bicycle simulator. Trajectories observed in reality are displayed as potential prescribed pathways across the simulated intersection. Participants in the simulator study are instructed to select and follow one of the prescribed pathways as closely as possible while responding naturally to other road users and obstacles in the environment. The resulting trajectory data is used to calibrate existing operation al and tactical path finding behavior models for bicyclists at signalized intersection.

The purpose of the work is creation of a set of technical means (switches, sensors) for recognition of transport infrastructure facilities, including development of algorithms for autonomous operation of technical facilities under changing environmental factors. In this work, we used methods for determining the volume of a three-dimensional facilities from the data of photo and video recording of the surrounding situation. The algorithm of technical vision was obtained, which is implemented as a program on a mobile device for recognition by means of stereometry of transport infrastructure facilities and their defects and storage of transport infrastructure defects. The novelty of the research is building of decision algorithms based on devices and sensors that recognize changing road conditions, namely, defects in coverage. The data obtained can be used in the planning of road repairs, in the analysis of traffic accidents by road police, road users for processing complaints, etc.

Increasing Demand

A trend in automotive freight has experienced rapid development in recent years. The increase of traffic intensities is closely related to the increasing demand of building elements of transport the infrastructure that will provide services to monitor traffic, inform road users and protect transport companies property and citizens who participate in the process of transportation. The current state of layout and allocation problem solving of elements of transport infrastructure is limited to the use of mathematical, multicriteria or heuristic methods. Each approach has its advantages and limitations but none of them solves same layout and allocation of a particular procedure with a specific position. System of blocks (SB) method is a method, which joints the layout and allocation into one unit, using the principles of mathematics, multicriteria, heuristic procedures and graphics simultaneously. The advantage of the proposed method is the complexity of the proposed solution, i.e. consideration of multi-criteria approach with no pre-defined positions and precise definition and the actual position of the elements in space allocation.

Surrounding Areas

We see, use and interact with different type of landscape every day. One of the important types is the road landscape we encounter during travel, whether a business trip, vacation or just on the way to and from home. Such landscapes can often help to introduce us to new regions or invite us to explore the surrounding areas because we partly experience the world around us from the road. Road landscapes combine important aspects of road and transport infrastructure as well as the quality of life of local people, traffic safety and tourism development. Road landscape development concerns both landowners and road users, each of whom might have different interests and understanding about possible landscape development and its consequences. Therefore, it is important to plan, discuss, present, and evaluate the future developments of any road landscape. The subject of road landscape has been little studied in Latvia. There are no recommendations on road landscape evaluation. Here we present a methodology for assessing perceptions of road landscapes. We aim to introduce several methods in combination that can be used in road landscape assessment, in order to show possible future developments of the road corridor and its surroundings and to test how potential changes might be perceived by road users. A combination of a case study approach, a scenario method, the use of 3D animations and of a web-based questionnaire survey are presented and discussed in the paper.
