Hi Lukas, I am glad you are interested in contgributing to OpenStreetMap. You will see that today there has been quite a bit of discussion on this list about collecting and analysing traffic information. I am sure you could make a valuable contribution to such a project. You are suggesting basing a project on the suggestion on the ideas list to use the GPX files in the osm database. The analysis method you develop could also be used in a more real time application if someone were to develop a service to collect and process GPX traces. I recommend that you have a look at our application template and start to draft an application based on your email. The main things to develop are the scope of the project (to judge success against), and a project plan/timeline to convince yourself (and us) that the project is achievable. There is a link from our ideas page to a page to store draft proposals for comment if you would like to use it.

My name is Lukas Kabrt and I am student at the Czech technical university in Prague. I am maping for about a year and I'm really enjoying it. Over the past few months I participated in import of administrative boundaries and in import of address points in the Czech republic. These two projects gave me a lot of experience with handling OSM data. I would like to use the knowledge in the field of artificial intelligence I gained during my studies and apply them in the world of OSM. I read through the wiki article GSoC Project Ideas 2010 and I like the Travel Time Analysis project [1]. I think this project has a great potentioal. As far as I know, routing algorithms estimate travel time by using speed limits or curvature of the roads. Using GPS traces from real vehicles will allow more accurate estimation of travel time, becouse it will take into accout other factors (traffic, condition of the road). With enought data available it should be even possible to detect rush hours or different traffic patterns through the week (weekdays vs. weekend) and give the appropriate travel time estimations. IMO the biggest challange would be to develop an algorithm which will match GPX traces to OSM roads. The algorithm has to deal with noisy GPS tracks, not-everywhere-accurate OSM map and it would be nice if it can handle low-frequency GPS tracks (e.g. 1point / min). Within the scope of GSoC '10 I'd like to create application, which will take an OSM file and bunch of GPS traces, analyze them, try to recognize traffic patterns and create the output file with estimated travel times for road segments (something like last year's Preprocessor to add altitude information to OSM data). If it prooves well it can be extended further.
