Financial anatomy of the E4 Helsinki-Lahti shadow toll PPP-Project. (2012)
Presentation / Conference Contribution
Leviäkangas, P., Wigan, M., & Haapasalo, H. J. O. (2012). Financial anatomy of the E4 Helsinki-Lahti shadow toll PPP-Project.

Purpose - Purpose: This paper investigates the returns to the investors and the state in private finance of road infrastructure. It uses an empirical case of the E4 Helsinki-Lahti road, which was built in 1995-1999 in Finland as the first real PPP-pr...

Developing a transition probability matrix as a measure of road network maintenance effectiveness. (2011)
Presentation / Conference Contribution
Mandiartha, P., Duffield, C. F., Thompson, R. G., & Wigan, M. (2011). Developing a transition probability matrix as a measure of road network maintenance effectiveness.

This paper presents a study that assesses the effectiveness of road network maintenance based on historical costs and road roughness progression. The study is intended to measure the effectiveness of routine maintenance and a combination of routine a...

The role of contestable processes in advancing sustainability in transport and planning. (2010)
Presentation / Conference Contribution
Wigan, M. (2010). The role of contestable processes in advancing sustainability in transport and planning.

Sustainable transport requires not only solid evidence to support policy and practice, but also to allow this to be examined with a high degree of transparency. Not all technical reports have the supporting evidence (or indeed models) made readily av... Read More about The role of contestable processes in advancing sustainability in transport and planning..

Stochastic based models for low volume road (LVR) network management. (2010)
Presentation / Conference Contribution
Mandiartha, P., Duffield, C. F., Thompson, R. G., & Wigan, M. (2010). Stochastic based models for low volume road (LVR) network management.

A major challenge faced by road authorities is to manage road networks within budget constraints and the uncertainty associated in predicting future performance of pavements; this is particularly true for the low volume road network. Road authorities... Read More about Stochastic based models for low volume road (LVR) network management..

The PCU values of motorcycles in congested flow. (2010)
Presentation / Conference Contribution
Lee, T., Polak, J. W., Bell, M. G. H., & Wigan, M. (2010). The PCU values of motorcycles in congested flow.

PCU (Passenger Car Unit) values are used in traffic management and transportation planning to calculate the flow volume in mixed traffic. However, the impact of motorcycles on road capacity is difficult to measure due to their ability to undertake bo... Read More about The PCU values of motorcycles in congested flow..

The passenger car unit values of motorcycles at the beginning of a green period and in a saturation flow. (2010)
Presentation / Conference Contribution
Lee, T., Polak, J. W., Bell, M. G. H., & Wigan, M. (2010). The passenger car unit values of motorcycles at the beginning of a green period and in a saturation flow.

The aim of this study is to estimate the Passenger Car Unit (PCU) values of motorcycles in two traffic environments: at the beginning of a green period and in a saturation flow. Motorcycles are able to undertake both lane-based and non-lane-based... Read More about The passenger car unit values of motorcycles at the beginning of a green period and in a saturation flow..

Identity, contestability and ethics of unified virtualisation of society. (2010)
Presentation / Conference Contribution
Wigan, M. (2010). Identity, contestability and ethics of unified virtualisation of society. In 2010 IEEE International Symposium on Technology and Society (ISTAS) (399-405). https://doi.org/10.1109/ISTAS.2010.5514616

Virtualisation (the replacement of physical representation by bits) in society is placing great pressures on individuals and society. The progressive loss of legal multiple identities raises major ethical and practical implications, and is being acce...
