Cause SNC to furnish to by November 30 of each the Association for its year, beginning on review and comment, a November 30, 1987, breakdown of proposed through Project total expenditures for completion the main road network (primary and secondary roads) among maintenance, rehabilitation, improve- ments and expansion.
1. For the purposes of this Schedule:
Transportation Sector. In 2011 under the initiative of Tbilisi City Hall the new comfortable minibuses have been introduced along with the improvement and optimization of bus and minibus routes, 241 “DAF” type buses were withdrawn from the fleet in 2010, decreasing the energy consumption and emissions. Furthermore, a number of measures have been introduced, which may be directly do not cause emissions saving, but they contributed to the increase of public transport attractiveness, significantly rising (by 34.4%) its overall passenger turnover. In particular:
Transportation Sector. In Ulaanbaatar, there are a number of major employers in the transportation sector. The state run transportation companies include MIAT Airlines, Mongolian Railway Authority, and Autobus 1,2,3. There are 152 companies providing inner city transportation, 26 domestic transportation providers and 4 international transportation providers. Of the 152 inner city transportation providers, there are 89 van companies and 52 taxi companies. In 2002, the volume of freight and number of passengers increased by 14.6% and 7.3%.7
Transportation Sector. The launching of the Mass Rapid Transit (MRT) phase one has successfully removed 9.9 million cars in 2017 and estimated to remove additional 62-89 million cars between 2020-2030.
Transportation Sector. This chapter describes the experience in technology transfer in the trans- portation sector about using ProB for data validation. More details of the approach is available in [LFFP10]. The following sections describe in detail the experience gained in different deployment areas, and the interactions be- tween Siemens and the University of Du¨sseldorf. On top of the mentioned ex- changes, a meeting was organized by the University of Du¨sseldorf at Siemens in Paris the 12th of January 2009, where (amongst others) ProB was in- troduced to several engineers at Siemens. Another more intensive training day was held the 25th of January 2010, where 5 engineers of Siemens were trained in using ProB for data validation. Also, the University of Du¨sseldorf has developed a xxxxxxxx0 for ProB especially targeted at the pattern of us- age of Siemens. These training activities seem to have been successful, as for the later deployments Siemens was able to use ProB independently of the University of Du¨sseldorf (see Section 4.5 below).
4.1 The Deployment Task STS are successfully using the B-method and have over the years acquired considerable expertise in its application. STS use Atelier B, together with in-house developed automatic refinement tools, with great success. Indeed, starting from a high-level model of the control software, refinement is used to make the model more concrete. Each refinement step is formally proven correct. When the model is concrete enough, an Ada code generator is used. This results in a system ensuring a very high degree of safety, with SIL4 certification. Indeed, quoting [Sie09]: “Since the commissioning of line 14 1xxxx://xxx.xxxxx.xxx-xxxxxxxxxxx.xx/ProB/xxxxx.xxx0/Tutorial One aspect of the current development process which is unfortunately still problematic is the validation of properties of parameters only known at de- ployment time, such as the rail network topology parameters. These param- eters are typically represented as constants in the formal B model. In order to avoid multiple developments, each software is made from a generic B-model and data parameters that are specific to a sub-section and a particular deployment. These data parameters take the form of B functions describing, e.g., the tracks, switches, traffic lights, electrical connections and possible routes. Adapting the data parameters is also used to “tune” the system. The proofs of the generic B-model rely on assumptions about the data parameters, e.g., assumptions ...
Transportation Sector. The mini-pilot from Siemens Transportation Systems (STS) is the function “Manage Operating Modes” in train system. Details can be found in Chapter 3 of the deliverable JD1 [ABB+09]. There are different models of the mini- pilot. The model of the mini-pilot from STS as documented in the Appendix A of the deliverable JD1 [ABB+09]. The model of the mini-pilot from Southampton as documented in the Appendix B of the same deliverable.
