  2. iTIXI Architecture and routingiTIXI Version 2.0 BUSPRO: Buchhaltung Provider: Email, VOIP Mandant: TIXIZUG Google: Geocode API Homeoffice Provider Provider (Home)Office Support Fahrer Firewall Firewall iTIXI app iTIXI db Disponent Manager Apache Symfony2 PHP (C++) MySQL dev-server Linux production-server Mandant: TIXIZUG Provider in 6300 Zug, Schweiz

  3. Geocoding Risk StatementiTIXI Version 2.0 • Providers of Geocoding Services can change the Terms of Use at any time: • Google Maps API updated to v3, causing much pain at dependent websites . • Some Providers (like OSRM in Karlsruhe) even forbid «Distance Table Computation», this is considered as excessive use. • Webservices have SLA typically stating 99.9%, however this is probably a marketing statement for «best effort». Who knows the better? • The Terms of Use usually contain a lot of legal mumbo-jumbo leaving a «normal» person utterly confused. HOWEVER, ONE THING IS CLEAR: PROVIDERS NEVER TAKE RESPONSIBILITY FOR SERVICES / CONTENTS. • THEREFORE A MULTIVENDOR FAIL-SAFE CONCEPT IS A PARADIGM FOR THE iTIXI APPLICATION. THIS WILL ENSURE iTIXI OPERATIONS, EVEN IF OR WHEN PROVIDERS OR TERMS OF USE CHANGE.

  4.

  5. Vehicle routing problem (sizing)iTIXI Version 2.0 2’884 customers • TIXI ZUG: 53813 rides/year, 144 .. 288 rides per day, in 3 shifts with 19 vehicles. • Per shift: (288/3 + 19) 2 = 13’225 route candidates per shift. • Per day: 288 rides ≅ 39’675 route calculations per day (max = 2x avg). • Initial load: Each route calculation is persistent (stored to the database). In due time calculations degress and all possible routes are persistent. • Base load = fluctuation of customer memberships ≅ 12% ≅ 1 member per day ≅ 2’884 route calculations per day. 2 m-VRPwT 115 13’225/shift 115

  6. Route calculations, load sizingiTIXI Version 2.0 Only mapquest (licenced data) covers the average basic load. Only mapquest (open data) is free and (reasonally) unlimited. mapquest (OSM data) bing google nokia mapquest (licenced data) 19’838 average initial load (degression) 2’884 basic load (average)

  7. Architectural requirementsiTIXI Version 2.0 response distance/time 8.2 km / 12 min request origin/destination 47.173601, 8.453111/ 47.194824, 8.518801 • Multivendor design • with individual load management • with vendor load balancing • minimum 2 vendors, having a common (free) or business licence • buying a business licence is an commercial decision (not technical, use non-commercial interfaces only) • licences must be registered to a iTIXI customer (g: Mandant-Ebene) • Local fail-safe for for non-persistant routes mitigates for • peak loads and • service outages • Keep routes persistant (database) Vendor1 Vendor2 Vendor3 local fail-safe persistant routes

  8. Local fail-safe requirementsiTIXI Version 2.0 • No internet routing access needed • Predefined grid of way points and distance/duration between each • Caculate distances to way points nearest to origin and destination • Read distances between these nearest way points from predefined grid • Sum the distance distance/duration pairs • Granularity of the grid defines the accuracy (<5% is good enough*) Bounding Box plus Zone Plan Footnote: each trip is calculated with a reserve of 5 minutes. 5% is less than 2.5 minutes for trips up to 50 Kilometers (inside Kanton Zug).

  9. Example: fail-safe grid (OSM-CH-DIDOK)iTIXI Version 2.0 All bus-stops in Kanton Zug and communities bordering on Kanton Zug (see zone plan). Addresses outside this area can be routed «on the fly» using web services or linear approximations, whennot available. Source: didok_bus_stops.xlsm

  10. Persistant routes requirementsiTIXI Version 2.0 • Size: approx. 10 mio routes (TIXI ZUG). • Each route inherits the isActive property from all referring nodes (passengers, POI) • Passengers may share addresses and routes (e.g. home for the elderly) • Auto-refresh routes in the evening, using open vendor quotas. • Store distance/duration totals. • Do not store route legs, waypoints, narratives, these are currently not considered as being usefull for the application. origin / destination 47.173601, 8.453111/ 47.194824, 8.518801 distance / duration 8.2 km / 12 min persistant routes

  18. Open Street Map SchweiziTIXI Version 2.0 OpenStreetMap Schweiz (Hyperlink) API GEOCODING , ROUTING , MAPPING , MAP-NODES  DIDOK • Swiss version of the OSM Overpass API: http://overpass.osm.ch/api/ • An XAPI interfaceis available at: http://overpass.osm.ch/xapi/ Nutzungsbegrenzungen • Overpass API is optimized for data consumers that need a few elements within a glimpse or up to roughly 100 million elements in some minutes, both selected by search criteria like e.g. location, type of objects, tag properties, proximity, or combinations of them • To support small and well scaling OSM main services, Overpass API is run as a third party service. You can use the public visible instances: • http://overpass-api.de/ with query base address http://overpass-api.de/api/ (4 physical cores, 32 GB RAM, Nürnberg). • http://overpass.osm.rambler.ru/ with query base address http://overpass.osm.rambler.ru/cgi/ (8 cores, 64 GB RAM). • Overpass API on openstreetmap.fr (Limoges) • Both servers have a total capacity of about 1.000.000 requests per day. You can safely assume that you don't disturb other users when you do less than 10.000 queries per day or download less than 5 GB data per day. response e.g. 47.173601, 8.453111 request e.g. Seemattstrasse 38, 6333 Hünenberg See Schweiz
