Re: [News] Dash, the internet-connected gps
The issue with traffic movements is you really need the cell tower movement information from carriers, without this these traffic flows are at best an estimation. As for openmoko: What about, in car GPS mode, reporting unusual speed fluctuations? Ex: you're on a 130 km/h road, and your gps reports 40 km/h = traffic jam. gprs link up, upload info + timestamp to community server When you query a car travel planning (i.e. ask your gps app to show you the way somewhere), do a simple query to the community traffic jam server; if the chosen path shows quite recent alerts, it would calculate an alternate ununcombered road. This could also be used periodically... ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
RE: [News] Dash, the internet-connected gps
Yep, coding easy to do however issues are- Mapping of roads and associated speed limits, almost non existent in the commercial space let alone in the open source space. Penetration, with only a few thousand Neo's in the USA by the end of 07 (if that) and maybe 20-30,000 by the end of 08 there will not be enough penetration to deliver the accuracy you need. It's a good idea but as we come closer to the commercial launch I think it's time for us to get a little more realistic about what is and isn't possible (at least in the first 3-5 years). Put it into your ideas drawer and bring it out later (or go and code a blackberry/windows mobile 5/symbian alternative to get the numbers you require) BTW feel free to ignore all of the above advice and go for it :) Regards, Dean Collins Cognation Pty Ltd [EMAIL PROTECTED] +1-212-203-4357 Ph +1-917-207-3420 Mb +61-2-9016-5642 (Sydney in-dial). -Original Message- From: [EMAIL PROTECTED] [mailto:community- [EMAIL PROTECTED] On Behalf Of Florent THIERY Sent: Tuesday, 10 April 2007 8:06 AM To: OpenMoko Community List Subject: Re: [News] Dash, the internet-connected gps The issue with traffic movements is you really need the cell tower movement information from carriers, without this these traffic flows are at best an estimation.

Re: [News] Dash, the internet-connected gps
My nav system knows the road type (primary, secondary, etc.) and then has settable speeds based on the type - 65 mph primary, 50mph secondary, etc. 'Good enough' estimate, but the realtime traffic/weather seems very useful. This is doable using traffic weather data from existing services that could be piped to the OpenMoko (or any device) say as a GeoRSS stream and then used to update predictions either on a server, or the handset. At least let you know things are bad ahead.

The last navigation system I had was able to predict how long it would take for me to get where I was going over many different roads..(highway,streets.. Etc) and then adjust it based on my actual speed and the distance remaining. I think the speed limits are in there also for that purpose. --Tim ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community -- Andrew Turner [EMAIL PROTECTED]42.4266N x 83.4931W http://highearthorbit.com Northville, Michigan, USA ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
RE: [News] Dash, the internet-connected gps
You don't need mapping data for speed limits. If a group of users share their data at a central server we can deduce the speed limit from past data. The server can learn which suggested alternative routes are the most effective for given traffic conditions. The server will know in real time what the traffic conditions are on many routes. This would be incredibly powerful when these devices become widespread and we form community servers for traffic information. We probably need to define open interfaces for this kind of server. The server algorithms would be very interesting. Johan PS: hopefully the LA server will tell everyone to give up and stay home so I can move around. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dean Collins Sent: Tuesday, April 10, 2007 5:35 AM To: Florent THIERY; OpenMoko Community List Subject: RE: [News] Dash, the internet-connected gps Yep, coding easy to do however issues are- Mapping of roads and associated speed limits, almost non existent in the commercial space let alone in the open source space.

Re: [News] Dash, the internet-connected gps
I would add that gprs is the only way to have a data link on a speed 50 km/h... And reporting stuff like average speed would be only a few ko ! ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
