Transport System Safety

Transport System Safety

As driving is a very complex mechanism that requires several processes, such as perception, decision making and action in terms of driving behaviour, it is not easy to analyse what specific reasons influence conflicts. It is generally accepted that human error is either unintentional or intentional.

The former refers to situations where drivers are not able to recognise warnings or signals.

On the other hand, the intentional errors refer to situations where they tend to make their own decisions based on their previous experience.

We investigate these two types of errors in order to make sure the drivers are fully aware of warnings which leads to safe driving behaviour.

Communication Technology in Driving Simulators

Recent decades have seen considerable growth in computer capabilities, data collection technology and communication mediums. Current communication technology among vehicles (V2V) and between vehicles and road infrastructure (V2I) allows to improve road safety and to minimise emissions in a dedicated short range communication networks. Advanced driver assistance systems based on cooperative concepts are keys to achieve them. Although, significant research has been conducted to study driver behaviour and responses to various traditional road based intervention, there is a lack of research on designing and assessing the combined impacts of new ITS based in-vehicle and roadside interventions on driver behaviour. Innovative communication algorithms will be developed by testing them in simulation environment. The project also explores the general data types used to develop, calibrate and validate these models. Recent technological development in in-vehicle data collection, driver simulators and machine learning offers considerable potential for improving the behavioural base, rigour and application of road simulation models.

Evaluation of railway crossing safety using ITS

Since industrialisation, trains have played a pivotal role in moving goods and passengers. Due to its advantages such as reliability, capacity and speed, the train has been used widely all over the world. As cities have physically expanded, new roads occasionally have had to traverse a train track to feed the shortest path for drivers. This has led to railway crossings at the interchange between the road and the train track. Like interchanges on normal roads, railway crossings generate a potential conflict area where collisions between vehicles and the train can occur. The safety of railway crossings relies mainly on motor vehicle drivers’ performance. Although emerging technologies and knowledge, innovative interventions and roadside interventions have been introduced in order to change driver behaviour, there is a lack of research on integration of Intelligent Transportation Systems (ITS) technologies to assess its influence on driving behaviour. Evaluating the danger level of railway crossings is very important for decisions related to the wise spending of taxpayers’ money. Rather than involving high levels of infrastructure spending, ITS can warn drivers of approaching trains and assist them to comply with the road rules when approaching and using a crossing.
