In this paper we describe the development of an electronic book, hypertext, or hypermedia document, as an alternate form of the paper based publication, "Drive Safe - A Handbook for WA Drivers" (Traffic Board of Western Australia, 1993). This handbook is used by all novice drivers who wish to obtain a motor vehicle driver's licence. It contains the basic knowledge required to understand the principles of road safety and road law, and thus enables novices to pass a theory lest on safe driving. The hypertext form of "Drive Safe" is to be distributed to teenagers in secondary schools throughout Western Australia. Research has identified this group to be at high risk of injury in road crashes. The development methodology, including integration of graphical and textual information, the advantages of the system, and issues confronting the developers is given. Demonstration of method and explanation of the underlying information technology will ensure that interested readers can replicate and build further upon this case study.


The cost of road crashes in Western Australia is estimated over $1 billion per annum (Western Australia Police Department, 1993). Teenagers and young adults are groups which are over-represented in these road crashes. One method of reducing the incidence of crashes for this group is through a better understanding of road safety and road law and thus improved road user behaviour,

In Western Australia fundamental information on road safety and road law is currently provided in a driver handbook titled "Drive Safe - A Handbook for WA Drivers" (Traffic Board of Western Australia, 1993). This handbook is provided free, from Police Department centres throughout the State, to assist all novice drivers who seek to pass a theory test and thus obtain a learner driver's permit to practise driving skills on Western Australian roads.

Research on an earlier version of the Drive Safe handbook indicated that for many people the text was difficult to read and understand. The handbook was subsequently re-written in plain language and diagrams simplified. This version is currently in its 3rd edition.

To further improve the dissemination of road safety information, the Drive Safe handbook has been converted into a computer based version, or electronic book, for use in secondary schools. The Traffic Board of Western Australia and the Injury Control Council of Western Australia have partially funded this conversion. There are a number of constraints on a computer based product targeted for schools:

This paper briefly describes the project and in particular the main features of the electronic book. The project essentially involved: The information technology used in the construction of this electronic book is known as hypertext or hypermedia. Schneiderman & Kearsley (1989) define it thus:
Hypertext is usually defined as the non linear viewing of information. "Non linear" means that you can examine information in any order you wish by selecting the topic you want to see next. It provides a new way of accessing and organising any type of information. Hypertext can make it easier and faster to find things and absorb ideas. Instead of having to specify keywords or search strings, you simply browse through a database by "jumping" from link to link.

The hypertext development system

The hypertext development system selected for this project was HyperShell, a professional hypermedia authoring system by Text Technology of the UK (Taylor, 1991). This system has been used by the Hyperware Research Laboratory at Curtin University for several years and has proven to be an ideal platform for developing and distributing general purpose hypertext applications for IBM PC platforms. Some of the reasons for selecting HyperShell for this project are as follows:

Converting the handbook into a hypertext

The methodology for converting the Drive Safe handbook into a hypertext included: The first task of the developers was to convert the written handbook into an electronic form from which the hypertext could be built. Fortunately the 2nd edition of the Drive Safe handbook was available from the Traffic Board of Western Australia as a MS Word 5 document. This enabled the developers to use the text to hypertext conversion tool, TXT2HTX, developed by the Hyperware Research Laboratory (1990). TXT2HTX consists of: One of the essential features of a hypertext is its links. Links permit the reader to move or browse through the hypertext in a non-linear fashion. Prior to making links, one needs to establish the sources and targets of the links, a process we refer to as 'knowledge engineering'. A critical decision here is to decide just how to refer to, or name, the chunks of knowledge. We adopted a naming convention for the individual frames, or chunks, of knowledge being mindful of the need to: The paper based version of the Drive Safe handbook is structured into sections and topics as shown by the Table of Contents in Figure 1:

Figure 1

Figure 1: Extract from the Drive Safe handbook

The handbook's structure clearly displays a partitioning of the body of knowledge into sections of topical relevance. The hypertext retains and extends this basic structure and removes non-essential components. Taking Figure 1 as an example, our naming convention translates to:

The sources and targets are then 'marked' with special codes for interpretation by HyperShell, and the 'marked up' document is processed by TXT2HTX. The result is depicted in Figure 2 as an extract from the hypertext's contents list. The first column lists a hot key assigned to that frame for selection from this list (the user can also use a mouse). The second column is the frame name and the third is the frame title.

Through the use of HyperShell's auto referencing facility, all frame names are highlighted throughout the body of knowledge as a link to the frame of the same name. This powerful feature provides a highly effective way to establish dynamic links between the major components in the body of knowledge. HyperShell also provides dynamic listings called paged lists that can contain these links.

The contents list in Figure 2 is an example of a paged list. To visit a frame using this list, the reader can either place the screen cursor over the frame name and 'clicking' the left mouse button, or by pressing the assigned hot key. Therefore to jump to the frame named "Foreword" (Figure 3), use the mouse to select the frame name or press the hot key "a".

Figure 3: An example frame

In this example, the frame is multi-paged as denoted by the page number and scrolling information displayed on the bottom line. This information and the 'page up' and 'page down' buttons on the toolbar (2nd and 3rd from the bottom right) do not appear unless the frame is multi-paged. To scroll through the frame, the reader simply uses these buttons, or the "Home", "Page Up" and "Page Down" keys.

Scanning graphics

A large selection of the graphic images within the Drive Safe handbook were scanned for inclusion in the hypertext version. Additional material was scanned from two pamphlets published by the Federal Office of Road Safety (FORS, undated, and FORS, 1985). This laborious process involved several steps: An example of a graphic 'popped up' over a frame is shown in Figure 4.

Hypertext functionality and useability

The user interface of the hypertext consists of: Each of these parts can be identified by referring to Figures 3 or 4. The menu bar occupies the first line of the screen, the frame name and title are in the first boxed area below the menu bar, the frame itself follows, and the toolbar is located along the right hand edge of screen.

The developers have built both text and graphical versions of the DriveSafe hypertext. In this paper we have elected to discuss the graphical version. The only difference between the two versions is the appearance of the user interface and some of the configurability. There is no difference in the main functionality of the hypertext as discussed below.

The menu bar

Each option on the menu bar may be selected using either a mouse, tabbing the cursor or pressing the first character of the option name, or 'hot key' as we refer to it. Actioning a menu bar item will pull down a submenu for the user to select. The menu structure by default is flat. This means that the user can not "traverse back up" the menu structure should they desire to do so. However as some users will be more comfortable with a hierarchical structure, this is configurable under the "Other" menu option.

The "File" menu has a number of file related options including the facility to browse the hypertext in a linear fashion, similar to the MS-DOS command "TYPE". This facility retains full hypertext functionality.

The "Contents" menu allows the reader access to the body of knowledge (frames and graphics):

The "Search" menu provides text searching and frame access methods based on text string manipulation. This includes the refinement and expansion of search criteria: The "Goto" menu provides frame access methods based on linear and logical frame navigation. For example: The "Other" menu allows the user to: The "Help" menu, provides the user with a pop up menu of help topics. Context sensitive help is implemented via the right mouse button when the mouse cursor is placed over a main menu topic. Figure 5 shows an example of a help menu.

The toolbar

The toolbar in the graphical version is an icon based interface to the main frame navigation and menu bar options. This approach will immediately feel comfortable to users familiar with graphical user interface (GUI) applications.

Some of the advantages of an electronic book over the printed handbook are:

Distribution and use

As indicated above, the target group for the DriveSafe hypertext are novice drivers in secondary education. The official launch of the DriveSafe hypertext will be conducted in February 1994 to coincide with the commencement of the new academic year. To assist teaching staff to assess its use in their curriculum for 1994, copies of the hypertext were pre-released in November 1993.

The hypertext is 'freeware'. Copyright permits the copying of the hypertext, but not for sale or profit. Indeed the developers actively encourage the free distribution of the hypertext so that the primary object of helping to improve the dissemination of road safety information can be achieved.

There are three main ways in which the hypertext can be freely copied:

The Hyperware Research Laboratory in conjunction with the Lightning Bulletin Board Service, both located at Curtin University of Technology, will be the main distribution points of the DriveSafe hypertext.


How can this hypertext be evaluated ? There are two main ways in which this can be achieved: The first approach would be directed to all learner drivers at the time of their licence application. The questionnaire would elicit details and comments about their use of the hypertext. This repository of quantitative and qualitative data can be used to assess and improve the interface, functionality and useability of the hypertext.

The second approach would only be directed to those schools and individuals agreeing to participate in this evaluation program. These participants would be required to forward the frame log data file to the developers on a regular basis over an agreed period. This could be done via the usual mail services, or by uploading the data file to the Lightning Bulletin Board Service. This evaluation technique will collect data such as frame visit frequency, sequence and times.

Both approaches will help to improve the dissemination of road safety information, and thus reduce the trauma and cost associated with Motor vehicle crashes on our roads.


The DriveSafe hypertext is another example of use of hypermedia in education and training. In this project, the developers have specifically targeted secondary school students in Western Australia. However, the Drive Safe handbook, and similar publications are also used by : The needs of these groups could be catered for in future editions by: In the current hypertext versions the reader is placed in a passive role similar to reading a printed book, but with superior information access abilities. Although there is a knowledge testing section (One Hundred Questions) in the hypertext, it is not implemented in an interactive manner. The developers have recognised the need to incorporate this feature and will do so in the next edition. The interactive test could easily become the theoretical test taken during the actual motor driver's licence test itself.

With the advent of virtual reality, this technology could also be incorporated into the DriveSafe hypertext, taking it into the realm of realistic simulations to underscore the learning. The trouble is where and when do we stop?


This project has been funded in part by grants from the Traffic Board of Western Australia, and the Injury Control Council of Western Australia under its "Injury Prevention Community Grants Scheme" initiative.

Technical assistance has been provided by Ken McCaw of the Hyperware Research Laboratory with regard to the scanning of the original graphical material. Further processing of this material was undertaken by Tembo Software.
