   en.wikipedia.org/wiki/Naismith's_rule

   Naismith's rule helps with the planning of a walking or hiking expedition by calculating how long it will take to travel the intended route, including any extra time taken when walking uphill. This rule of thumb was devised by William W. Naismith , a Scottish mountaineer , in 1892.

3. Value of time - Wikipedia

   en.wikipedia.org/wiki/Value_of_time

   The time that one spends travelling can't be spent on studying or working; in that sense, time is money. Geographer Andy Nelson (University of Twente) created a map to calculate how much time is wasted. In transport economics, [1] the value of time is the opportunity cost of the time that a traveler spends on their

4. Journey planner - Wikipedia

   en.wikipedia.org/wiki/Journey_Planner

   Trip planning or journey planning is sometimes distinguished from route planning, [4] which is typically thought of as using private modes of transportation such as cycling, driving, or walking, normally using a single mode at a time. Trip or journey planning, in contrast, would make use of at least one public transport mode which operates ...

5. Travel time reliability - Wikipedia

   en.wikipedia.org/wiki/Travel_time_reliability

   Travel time reliability has been increasingly recognized as a key performance indicator for transportation roadways and transport systems, which exerts a strong influence on the stakeholders in transportation networks, including users (travelers), service providers, planners, and managers. This has stimulated research into the development of ...

6. Space travel under constant acceleration - Wikipedia

   en.wikipedia.org/wiki/Space_travel_under...

   At a constant acceleration of 1 g, a rocket could travel the diameter of our galaxy in about 12 years ship time, and about 113,000 years planetary time. If the last half of the trip involves deceleration at 1 g, the trip would take about 24 years. If the trip is merely to the nearest star, with deceleration the last half of the way, it would ...

7. Interstellar travel - Wikipedia

   en.wikipedia.org/wiki/Interstellar_travel

   For example, a spaceship could travel to a star 32 light-years away, initially accelerating at a constant 1.03g (i.e. 10.1 m/s 2) for 1.32 years (ship time), then stopping its engines and coasting for the next 17.3 years (ship time) at a constant speed, then decelerating again for 1.32 ship-years, and coming to a stop at the destination. After ...
