Journal Article
Wigan, M. (2012). Contestability, democracy and trust in the anti-terror age. IEEE technology & society magazine, 31, 26-32. https://doi.org/10.1109/MTS.2012.2185730

Checks and balances in government are always difficult to resolve, and as both societal and governmental complexity have increased, the degree to which expertise and policy reside within government has declined. The rise of evidence-based approaches... Read More about Contestability, democracy and trust in the anti-terror age.

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

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, January). Developing a transition probability matrix as a measure of road network maintenance effectiveness. Presented at 90th Annual Meeting of the Transportation Research Board

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...

Enhancing community participation in Metropolitan strategic transport planning through shared analysis (2011)
Journal Article
Sunter, P., & Wigan, M. (2011). Enhancing community participation in Metropolitan strategic transport planning through shared analysis. Road and Transport Research Journal, 20, 24-35

This paper assesses and explores the existing potential for new approaches to software and data, such as the open source movement, to contribute to more open and contestable strategic land-use and transport planning processes. Issues with the current... Read More about Enhancing community participation in Metropolitan strategic transport planning through shared analysis.

The role of contestable processes in advancing sustainability in transport and planning (2011)
Journal Article
Wigan, M. (2011). The role of contestable processes in advancing sustainability in transport and planning. Road and Transport Research Journal, 20, 32-40

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.

Owning identity-one or many-do we have a choice? (2010)
Journal Article
Wigan, M. (2010). Owning identity-one or many-do we have a choice?. IEEE technology & society magazine, 29, 33-38. https://doi.org/10.1109/MTS.2010.937026

The rapid growth of databases, biometrics, and RFID has led to an environment where identity-related technologies are approaching a critical mass as a potential means of controlling the population. The essential aspects of these diverse technical adv... Read More about Owning identity-one or many-do we have a choice?.
