A participatory approach to urban transport planning in developing countries

Traditionally transport planning and policymaking has used quantitative surveys to predict future demand for public transport. However, this paper argues that a more participatory approach is required in order to better understand household activity patterns and the impacts and implications of travel on livelihoods. Such an understanding will enable transport planning and policy to support the needs of lowincome people and achieve broader poverty alleviation objectives. This paper draws on case studies undertaken in Harare (Zimbabwe), Accra (Ghana) and Colombo (Sri-Lanka) as part of a broader study carried out for the DFID Knowledge and Research Programme. The authors look at the impact of public transport on certain dimensions of poverty, consider the links between urban transport and other sectors (health, education and employment) and summarise key methods of enquiry that might be adopted in effecting a more participatory approach to transport planning

Investigation of the mechanisms leading to the electrical breakdown of a triggered water gap

The breakdown of a triggered, plane-parallel electrode system with water dielectric has been investigated. The gap was triggered by a discharge initiated at an electrically isolated trigger pin, positioned in the center of one of the electrodes, using a 500 ns voltage pulse. A 5000 fps CCD-camera monitored events occurring in the gap during such a discharge and the intensity variations of a laser beam transmitted through the electrode gap was also monitored. The results indicate the initiation, expansion and collapse of a gas bubble generated at the trigger electrode. The subsequent application of a voltage between the plane electrodes results in the complete breakdown of the gap due to the trigger discharge. The effect of a delay time between the trigger pulse and the application of the main gap voltage was consistent with the growth and collapse of the trigger-initiated bubble
