Road Safety Research Priorities On-line Survey

Introduction


The invitation to participate in the first round of this exercise outlined the purpose of the survey and will not be repeated. That information can still be accessed at the the IPENZ Transportation Group website

Outline

As the survey progresses the aim is to focus on priority areas for road safety research. This is acheived by asking each respondent to allocate a nominal research budget across topic areas.

The results of the first round are presented below.

Budget

Based on your responses the list of research topics has been reduced to 27. You may notice that some of your preferred items are not included in the revised 27 questions. If this is the case, and having considered the rest of the groups' responses above, and you want the item back in the list, add it in the additional items boxes.

The budget works similarly to the first iteration except that the total budget you have to distribute is $30. This is equal to the number of questions plus additional items, so if you want to put more weight on one item, another item must drop off the list. The survey allows whole numbers only, e.g. 0, 1, 2. Similarly for additional items. A calculator is provided at the bottom of the page to help you keep track of your budget. Please allocate amounts now in the column labelled BUDGET.

Part 2: Interactions

The important interactions that were highlighted in the first survey are shown below with the average budget spent.

You are invited to choose one more interaction, using the pull-down menus which refer to the items in the table above. Then allocate a further research budget of $5 over all the interactions. This is equal to the number of interactions, so if you want to put more weight on one item, another item must drop off the list. The survey allows whole numbers only, e.g. 0, 1, 2. A calculator is provided at the bottom of the page to help you keep track of your budget.
