comment How to create a service area using both streets and buslines in the same network?
Couldn't you just do a buffer that incorporates bus stops, let's say 400m (0.25 miles)?

Thanks for the advice, I just sent them an email and we will see. On a further note, I haven't checked your blog in a while, thanks for answering and reminding me of its awesomeness

comment Looking for best practices for determining turn penalties
@BicycleDude I do not think that heuristics "suck", rather GIS solutions usually work best on "macro" rather than "micro" problems. Turning penalties and restrictions are analyzed for a small number of intersection(s) (micro level) as apposed to applying generic factors (macro). To model trip volumes, usually a modeller does an intersection per intersection analysis to determine the penalties based on volumes, gaps, green cycles, geometric layout, etc. After determining those values you can initiate the trip assignment phase to get a modeled output for volumes per roads

Can you use proj4, Gdal, or any other library to do the transformation from ESPG_X to ESPG_Y?

comment Is city-supplied GIS data sufficient for transit operators or do they need their own set of GIS data?
For lane location usually, loup detectors installed per lane coupled with transponders are used. The transponder is a bluetooth or rf receiver that detects a "sender" signal in the bus/truck. The loop sensor identifies the bus's location. This setup usually costs $75,000 to $150,000 per site and can usually collect close to 25 variables per vehicle. The issue with pinpointing an object that is fast moving is that there still needs to be some form of a mechanical/analog system to pinpoint the bus/truck's location. Add to that the transponder is used to sort the vehicles to identify the buses

comment How to track logged in user in geoserver?
Can you pass the user.ID variable to the log you're already maintaining? I assume if the instance is running and the user is logged in, their user.ID variable will be stored somewhere.

There are better examples on their site, but in this example double click the cursor on the map. If you look at their examples page, there are a few options for you to consider.

comment How do I safely store paper/hardcopy maps?
I see that you're in Ottawa. There is a map collectors shop downtown on sparks, not too far from Black's I think (I haven't been there in a few months). Anyways the old couple that run the place will give you amazing advice on how to preserve these maps
