Just a note to follow Python Pep 8 when you're coding in python. Here's a handy dandy pep-8 checker

comment Arcpy: Names and distances of nearest intersecting roads in layer 1 to end points of a road segment from layer 2
Thanks for the solution, I don't have 10.2. We're still on 10.1

comment What can I use to calculate drive times /with/ traffic considered?
I think you're oversimplifying a very complex problem. How many nodes (distribution centres/stores) do you have in total? Are you trying to develop an origin/destination (O/D) trip table matrix based on time/period of day? Are there any restrictions on how many hours can a driver be on the road? restrictions on worker shifts, time of day, day of the week?

Hi Richard, for some reason, this method is duplicating a lot of links and also creating new fmeasures of -0.000023. any suggestions?

@KirkKuykendall A piece of road can only either have one event scheduled or none. However, that event could be over many segments (control sections) and do not necessarily match the boundaries. i.e. it could start half way and end 3/4 of the way of a segment. So an example Route_1_control_Section_1 2.5 to 10.6, Resurface, Route_1_control_section_2 0.0 to 3.8, crackseal. Conversely 95% of the existing segments (layer_1) will get no work scheduled next year.

@KirkKuykendall Did my above comment answer your question?

@KirkKuykendall - Field personnel take layer 1 and assign where where work is scheduled using excel in the form of ROUTE_ID, FROM, TO, DATE . I then took that information and created an event layer about it. The result should be merged into Layer_1 yet pereserving the attributes.

as a note, I don't want to maintain duplicate segments, Scheduled events should replace existing portions of layer 1. They'll have the attributes from layer 1 and the new ones from layer 2

comment Selecting maximum Value based on other field using ArcMap?
If you can use ArcPy or python in the data. Loading it into a list then doing a for loop makes it quiet easy. data = [(100,1), (200,1), (300,2), (500,2), (100,1), (400,3), (400,2), (200,1), (200,4)] d = {} for former, latter in data: d[former] = max(latter, d.get(former, 0))

comment How to create a line layer which connects a point layer to a line layer?
Thanks Pedro, I do lots of Transit and Traffic plans, but now moving to doing a lot of it through Python, ArcGIS, and QGIS. I will try and implement your answer in the next few weeks. To answer your questions in your post: I'm testing a traffic demand model on 1,000 small zones to see how it performs, and then I'll modify the dummy links manually where I see fit.

Have you considered getting a map-less data logger you can throw in your backpack or on your key chain to accompany your handheld device? These things can run you between $50-$200
