Story and presentation

Story

IBPindex was born in 2003, when a mountain bike and road bike fan group started to save the tracks of their routes registered in their GPS in an excel sheet.
The position in 4D in numerous points of a route, gave us a lot of information that we started to compare.
When we observed this data, we had the idea of finding an index to value a bycicle route hardness.We started to combin, to value and modify 19 different parameters to obtain a first reference punctuation. During some months, we compared the route sensations with the punctuations that we obtained and we corrected the factors to adapt them.
We obtained a first formula and in the next trhee years we modified them acording to the average values that we obtained in our routes.
At the end of 2006, a technical team developed the necessary programming to make available the posibility of using IBP index through a web page (www.ibpindex.com) and a desk aplication to the whole cyclist comunity.
In a few months it became a very valued tool for cyclists and turned into a reference index for a huge amount of clubs.

Technical aspects
|
|
IBPindex is a punctuation that values the difficulty degree of a bike route ( btt or road)
It is obtained analyzing high, length and latitude data in multiple points of the route. This points are obtained from the track registered in the GPS, which gathers them automatically with a cadence of 20-40 points per Km, acording to the terrain variations, the direction changes and the kind of GPS. From this points, it is calculated the crossed distances in different rise and descent streches (1%, 5%, 10% etc…), it is calculated the % of the average rise and descent ratios, the total kilometers and the distribution of the rise stretches, It is also taken into account the vertical and horitzontal direction, and the high of the crossed distance..
It is applied a no linear mathematical formula and it is obtained a punctuation between 0 and infiity. This is a 100% objective punctuation because it is not taken into account any subjective value, as it could be climatology, physical condition or race pace.
In this formula there are taken into account 19 parameters, which were adjusted during a period of 3 years, analyzing and comparing multiple routes, by a cyclist team.

Characteristics
|
|
IBP system detects and corrects automatically the track points with an excessive high mistake that usually GPS detects. It optimize the track points and compare the results to obtain final data much more reliable, (especially in accumulated rise and descent meters)
It detects automatically the kind of track (btt, road, trecking, flight, etc...) and it distinguish between real tracks and drawn tracks.

|
|
Functionality
|
|
This index is useful to know the difficulty degree of different routes comparing them. As it does not take into account subjective factors, this will be a personal value for everyone.
After comparing some routes, we make a punctuation scale that is useful to know the difficulty degree of a route before doing it.
Another way to use IBP is to know the difficulty of a new manually drawn route in a map like "OziExplorer©” " or "CompeGPS©” ". As long as the track points have the high information they will be valid to obtain the index.

Other aplications
|
|
In the last months, the mountain comunity has aks us for an adapted IBP for walking or running routes.
Taking into account that GPS are nowadays more and more accesible and more especialized to this kind of sports, we are working to adapt IBPindex to the trecking routes.
The accumulated analysis in our data base also will permit us in a short time to develop a new index to know the physical condition. In a scale of 0-100 we will be able to compare our physical condition with thousands

Analyzing..., Comparing
IBP index is a punctuation that values the difficulty grade of a mountain bicycle route or a road bicycle route.
It is obtained by analyzing length, latitude and height data in multiple points of the tour.
This points are obtained from the recorded track in the GPS, which collect them automatically with an aproximated cadence of 50 points per kilometer, depending on terrain variations and direction changes.
With that points, there are calculated the covered distances in the different rise and descent stretches (1%, 5%, 10% etc...). The representatives % above the total, the total raised and descended meters, the raise and descent average ratio, the total Km and the rising stretches distribution are calculated.
Track points recorded per Km
Track points recorded per Km
The points per Km that GPS records are a decisive factor in the collected data reliability.
The total recorded points do not affect to the total covered Km, but they do in the accumulated rised/descended meters.
If there are recorded a few points per Km, we will have poor information, so that the total meters accumulated will be less than the real ones. If we have a lot of points, then we will have too much information and too much accumulated mistakes, so that the accumulated meters will be more that the real ones.

Acucmulated meters
Accumulated rise/descent meters
The total rise/descent meters that IBPindex show in the first analysis (repaired analysis) is strictly the sum of the GPS registrations. The GPS receptors usually accumulate some more rise or descent meters due to the sattelites.
In a second analysis (optimized analysis) it is applied a slope corrector that makes a more real value. The newest receptors are more and more precise and so they accumulate less mistakes.
Estado del terreno
We search translators in English
| Estado del terreno en las salidas de montaña (BTT) |
| El estado de los caminos propiamente, (sin contar con la climatología), podríamos considerarlo como un valor objetivo, aunque siempre nos podrán asfaltar un trozo de camino, allanar unas regateras, o limpiar de pedruscos un tramo, podemos pensar que mas o menos los trazados se mantendrán siempre de manera parecida. |
|
La lógica nos anima a pensar que el estado del terreno influye de manera crítica en la valoración de la dureza de una salida
|
| En cierta manera así es, pero los estudios de mas de 100 rutas diferentes entre personas de distintos niveles, nos demostraron, no sin cierta sorpresa, que la influencia de ese dato era menor de lo esperado. |
Punctuation format
First two numeric digits
Difficulty route degree valuation, scale between 0 and infinity.
First IBP index reliability letter
A= very good reliability (between 85% and 100%)
B= good reliability (between 70% and 85%)
C= acceptable reliability (between 60% and 70%)
D= poor reliability (enbetween 40% and 60%)
E= bad reliability (between 0% and 40%)
M= manually drawn track
Second letter: route characteristics
A= BTT +
B= BTT -
C= mixed
D= road+
E= road -
Explanatory note;
The route characteristics valuation (second letter) does not refere to if we have gone through paths, road or tracks, it refers to that the recorded registrations of the gps, are thypical of BTT or road routes.
Example:
A road route has a higher velocity average than a BTT route
A BTT route has more see-saw than a road route
A road route has more straight stretches than a BTT route
and so on with all the registrations.

Track mistakes
Track mistakes
|
|
IBP system detects and corrects automatically heigh mistakes of the tracks.
The GPS regists, sometimes, track points with an excessive heigh mistake margin. This peaks are easy to see when whe represent the track in a graphic.
The mistake correction is done in two times, or two track analysis. In the first one, it is replaced the mistaken heighs with other ones calculated in that point. In the second one it is calculated the IBP index in a free mistake track.
