The document discusses transport policy and funding challenges faced by the International Transport Forum (ITF). It notes that the ITF is an inter-governmental organization with 54 member countries that focuses on global transport policy issues and provides comparative statistics and research. It states that transport policy is difficult due to its impact on people's lives and different stakeholder interests. A mix of policy tools is needed, including supply, regulation, pricing, and information strategies. Funding transport requires balancing long-term impacts versus short-term results and considering who benefits and pays for investments. Knowledge sharing across countries is important given the complex nature of these issues.

The document discusses a PhD project called S-City that aims to understand how information and communication technologies (ITS) can impact mobility and safety while addressing privacy issues. It outlines how ITS has the potential to enhance mobility through information, monitoring, localization, identification, authorization, and communication technologies. However, these applications raise privacy concerns regarding lack of control over personal information, risk of social exclusion, and compromising of privacy. Examples are given of privacy issues around data retention by transportation agencies and mobile phone tracking. The document argues that privacy is important for individuals' well-being and democratic societies, and that its loss can result in harm.
The document discusses connectivity technologies that enable connected vehicles. It provides examples of applications for connected vehicles in urban and interurban areas that improve efficiency, safety, and sustainability. Connected vehicle technologies allow for wireless asset management solutions that optimize maintenance schedules based on real-time vehicle sensor data.
This document discusses transport security and provides definitions and context. It summarizes regulatory initiatives at international levels, such as by the UN, EU, and IRU. It defines transport security as protecting infrastructure, goods, and people from deliberate attacks, as opposed to transport safety which includes general safeguarding from any harm. International regulatory bodies have proposed various security considerations for vehicle regulations, infrastructure networks, dangerous goods transport, and border crossings to strengthen transport security.
This document summarizes a presentation on the impact of water on road degradation. It discusses a research project studying water movement in road structures and presents field observations from moisture monitoring programs. Specifically, it shows how moisture levels varied with depth and temperature over time. Charts are also shown comparing measured stiffness values from road tests to gravimetric moisture content readings. Finally, it describes an instrumented test section and procedure used to study the effects of water on measured responses like pressure, strain and deflection.
The document discusses unsaturated water flow in pavements. It aims to understand how water moves through pavement structures, how long it remains, and what factors control moisture conditions. It compares saturated versus unsaturated flow, and notes unsaturated flow is slower. It describes using actual pavement geometries and material properties in a finite element model to calibrate predictions of water content from sensors to observed field data. The model is adjusted based on precipitation data and material densities to improve prediction accuracy at different sensor locations within the pavement structure.
