1. Introduction Speed & Route Profiler is designed to give information to a driver who can then follow a set route at a set speed profile. The interface with the driver is an OLED display with an internal buzzer. Each Driver system will include an OLED display with 4Mb memory to store the route information, an inbuilt buzzer, and special firmware.
It is possible to drive the route in two or more parts by appending two files together. This is handled by the Speed & Route Profiler software. Note the maximum journey length is approximately 8 hours, this is determined by the amount of memory in the OLED. VBOX without hand held event marker For very simple routes, it is possible to add the turn points after the route has been driven using the Speed &...
3. Speed & Route Profiler Software Whatever method you use to capture the data, you will always need to load the Speed & Route Profiler software to edit the data and then download it to the OLED unit. 3.1 Create file from driven Route If you have data from a Reference driver, in the form of a .VBO file, you should select File ...
File Dropouts If your VBO file does contain GPS dropouts you will first need to repair these by entering the missing data. Click on OK in the information box (shown above), and you will see the following display, indicating in this case that you have 5 dropouts that need to be repaired.

File Dropouts - contd Insert curved line In certain cases the dropout cannot easily be fixed by moving a straight line, see the example below. Press the Ins key and a dot will appear in the centre of the line on the left. By clicking on this dot (with the left mouse key), you can move it up or down the line.
3.3 Main screen When you have loaded a VBO file, and repaired all the GPS dropouts, you will see the screen as below, with the filename displayed at the top, in this case “Bucks Town Plus1.vbo”. The screen is split into three segments; detail map, point setup and route summary. The first segment, referred to as the detail map requires that you have an internet connection and it shows the first part of your route zoomed in and superimposed over a Microsoft Bing map.
3.4 Add and Remove route points Add Point To Add a new route point, click on the nearest point on the route summary, and you will see this section of your route on the detail map. Next pan around the detail map, by pressing the left mouse key whilst moving the cursor around to find the exact place where you wish to insert a new route point.
3.5 Point Setup Whether points have been added using the hand held event marker or by adding points as detailed above, you will now need to provide instructions for the Driver which will appear on the OLED display. These instructions include an icon which will appear on the OLED, such as a left turn or a roundabout sign and also the warning distance before the driver should make the turn.
You will need to set up details for every point on your route. Select both Point set-up Instructions and Warning distances for each point. The warning distance will be estimated by the program, dependant on the speed of the reference vehicle before this warning point. This warning distance can of course be changed as required.
3.7 Editing Speed Short distance Under certain circumstances it may be necessary to edit the speed for a small section of the route. This will perhaps be due to a slow moving vehicle driving in front of you on a major road where it is not your intention for a driver to slow down at this point.

Editing Speed - contd Once you have zoomed in on the graph you will see something like the graph as shown below. Next, hold down the shift key and click with the left mouse key on the start point, where you wish to adjust the speed and then click on the finish point. Then let go of the Shift key. This will highlight the area as shown above.

Fixed Speed Long distance Certain tests require a driver to remain at a fixed speed over a long distance, perhaps on a motorway. Whilst the Reference driver may attempt to maintain this speed, it may prove difficult, due perhaps to slow moving traffic, yet it is required for the driver to try to maintain this fixed speed where possible.
3.8 Appending VBO Files If you wish to join two VBO files together, due to the Reference driver stopping for any reason, then the file option File Append should be selected. At the top of the box, you will see Select first file. For now, just enter the name of the first file or click on one of the files in the list.
3.9 Speed Profile from existing data In certain cases a speed profile will already exist in a tabular format, such as that shown below. This information is widely available on the internet. EPA Urban Dynamometer Time Speed (sec.) (m.p.h.) 11.5 14.3 16.9 17.3...

Speed Profile from Existing data – Contd Now load Speed & Route Profiler software and select File Load, enter the name of the MS Excel file. You will see the box below. In this case the time interval is 1 second and the units are miles per hour. Click on OK and the data will then be loaded into the program and the graph of speed versus time will be displayed.
3.10 Create Speed Profile manually The last method of creating a Speed Profile is to create it directly by entering the speed and time figures that you wish to achieve. To do this, load the Speed & Route profiler software and select File Create. You will see the screen below, and if you click on Help you will also see the display on the right.
3.11 Options Menu There are 4 choices under the Options menu; Fix file, COM Ports, Distance units and Language. 3.11.1 Fix file When you load a VBO file you are warned if there are dropouts within the file. If you ignore this warning you can later fix the dropouts by selecting Fix file under the Options menu.
3.11.4 Language This option allows you to select between Deutsch and English language. Selecting this option changes the language to Deutsch and will cause the program to restart. 3.12 Send to Unit To download either a Speed Profile .SPP or a Speed & Route profile.SPD to the OLED, click on Send to Unit in the toolbar.
4. Equipment Setup The driver should fix the OLED display to the vehicle windscreen such that the vision of the road is not impaired. The OLED should be connected to the VB Micro using a CAB077 cable, and the VB Micro should then be connected to the cigar lighter power supply using a CAB060 cable.
5.5 Clear Journey This allows the user to clear journey information and start again. Once this is pressed the user will be returned to Drive to Start. 5.6 Show % Time variance If this is activated (by pressing square key), then the percentage time variance will be displayed on the right hand side of the display.
6. Driver Operation Initially you may see LOW SATS on the display. However, once more than three satellites (SATS) are received on the unit, the driver will be prompted to Drive to the Start. He/she should then follow the instructions on the screen as shown below, or on the alternative graph screen (see display graph option on the previous page);...
7. Display messages Wrong Direction The driver is on the right route, but is going in the wrong direction. Wrong Route The driver is NOT on the right route, but was on the right route within the last 120 seconds. Low Sats This is displayed If satellites (SATS) are less than or equal to 3.
