I have four points representing harbors along the coast. I also have a roads layer that has info on each road segment such as length, speed limit, and travel time.
I calculated travel time with [(length in miles) / (speed limit in mph)] * 60 for the time it takes to traverse each road segment in minutes.
What I want to do now is: Work out from each harbor point along the road networks to get the total travel time to the nearest harbor for each road segment. All the tools I've found that do something similar to this require both a start and end point.
Is there a way to do this without turning each road segment into a point itself?
To better visualize my end goal, I essentially want a sort of "Euclidean Distance" effect, except it needs to stay along the roads layer and will total in time rather than meters/miles/etc.
I am using ArcGIS Desktop 10.0.
