Furthermore, production technology, automatic surface finishing, microelectronics and optoelectronics are also represented. In 2005, Rodgau's commercial operations made available all together 9,076 jobs on the social insurance rolls. Moreover, there were roughly 3,000 jobs for the self-employed, officials and those marginally employed. A great number of Rodgau's working people have jobs in the nearby cities: Frankfurt am Main (25 km away), Frankfurt Airport (30 km away), Offenbach am Main (15 km away), Hanau (15 km away), Darmstadt (20 km away) and Aschaffenburg (20 km away). Transport Local public transport Since 14 December 2003, all Rodgau's constituent communities have been linked to the broad network of the Rhine-Main S-Bahn by the extension of line S1 from Wiesbaden to Ober-Roden. Until that time, Rodgau had been served by the Rodgaubahn (railway). There is regular bus service to the railway stations at Nieder-Roden and Jügesheim on the S1 through district buslines to Babenhausen, Seligenstadt, Dietzenbach and Langen and town buslines to Hainhausen, Weiskirchen and Rollwald. Cycle path network The town of Rodgau is slowly finding at its disposal a network of cycle paths which are being laid out in collaboration with the Allgemeiner Deutscher Fahrrad-Club (“General German Bicycle Club”, ADFC), and which link all five constituent communities together. Since 2005, the signposted Rodgau-Rundweg has run through fields and woods right round the town. At 42.1 km in length it runs to almost marathon distance. On both sides of the S-Bahn line, a 14 km-long, asphalt-paved cycle path from Rollwald to Weiskirchen links all constituent communities. Special bicycle parking places with stands and lockable rental boxes are to be found at every S-Bahn station. Pedestrian precincts Pedestrian precincts have been laid out in Nieder-Roden between the S-Bahn station and Puiseauxplatz (square) and in Jügesheim on Rodgau-Passage. Areas with much reduced traffic with their attendant paving can be found in all constituent communities, mostly in the old community cores and in new development areas. Walking paths through the Rodau-Aue in Dudenhofen and Jügesheim, partly laid out like a park, are reserved for pedestrians. An extensive network of signposted hiking trails threads its way through fields and woods in Rodgau's municipal area. Roads In Rodgau's north, the A 3 (Frankfurt-Würzburg) runs through the municipal area and crosses Bundesstraße 45 (Hanau-Dieburg), which has been expanded to expresswaylike proportions, and which runs north-south, touching all constituent communities, and has four interchanges.
