What Curriculum for Mobility and Transport Studies? A Critical Exploration

To understand the complex meanings of mobility and to engage in transport planning and management processes, a variety of disciplines, skills, and tools are potentially useful. Universities have a limited amount of time and resources to train future professionals though. This poses a problem: where should the teaching priorities be? By means of a web-survey, this study has asked academics based at a number of universities what the disciplines, skills, and tools that — according to their personal viewpoints — are the most relevant for practitioners in the mobility and transport sector. The respondents generally support curricula that facilitate a holistic, non-specialised, understanding of mobility and transport issues.     

Determining strategies to increase response rates in transport surveys of small shop-based businesses

Increasing representation of small business perspectives in policy research would benefit from identifying strategies to increase response rates. Despite the significance of the issue, there is inconsistent reporting amongst small business research about issues such as sampling, recruitment and survey design. Reporting on such issues may help address the under-representation of small business respondents and help reduce wasting research resources on less effective strategies. For policy matters that have the potential to disrupt how small business owners run their business, this is of particular importance. This paper reports on a survey of small businesses about changes to the transport accessibility features of a town centre that have the potential to affect the supply of car parking. Based on a review of the available literature, strategies were adopted to reduce respondent burden and maximise engagement. The paper presents an analysis of recruitment approaches in the first wave of the survey and demonstrates how the refinements to the recruitment approach were successful in achieving an increase in response rate from 40% to 47%.
