Trekking and Hiking Times

Trekking and hiking time rule MATLAB implementations for Naismith's rule, Naismith's rule with Aitken-Langmuir corrections and Tobler's rule.

Naismith's rule

• Function available in naismith.m
• Example plot available in naismith_plot.m

Example

track_length = 20;  % km
ascend = 1;         % km
[w, t] = naismith(track_length, ascend)

Naismith's rule with Aitken-Langmuir corrections

• Function available in naismith_al.m
• Example plot available in naismith_al_plot.m

Example

base_speed = 4;     % km /h
track_length = 20;  % km
ascend = 1;         % km
[w, t] = naismith_al(track_length, ascend)

Tobler's rule

• Function available in tobler.m
• Plot will be generated when called without return parameter

Example

slope = tand(10);   % tand(degree)
track_factor = 1;   % e.g. 1 (footpaths), 0.6 (off-path)
[w] = tobler(slope, track_factor)

% create plot
tobler(slope, track_factor)

Tranter's correction table

Correction table to Naismith's rule.

• Table available in tranter_table.m
• Least squares best-fit function available in tranter.m
• Plotting of these two in tranter_plot.m
• Fitting testbench in tranter_fit.m

Example

time = 5;           % hours
fitness = 25;		% Tranter minutes
[t] = tranter(time, fitness)
