RavKavRavKav Web application supplying an easy way for retrieving Web application supplying an easy way for retrieving
information about public transportation in Israel.information about public transportation in Israel.
RavKav allows getting all information about public transport in one web site. By entering RavKav's site the user can get information about bus/train lines, information about lines going through stations, information about traveling paths
containing lines from different companies which were built according user's preferences (time, price, etc') and many
other general information about public transport.
In Israel there are more than 10 public transport companies.
Each company has web site for providing information about
it's lines. This situation forces the user to enter many sites to
get information about different lines (and all this after figuring
out the company responsible on specific line). In addition,
there is no way to get traveling path containing lines from
different companies.
RavKav was built using the most up to date development tools:
ASP.NET technology,C# based system core,
Microsoft.NET based graphic module and SQL Server database.

Paths assembling algorithmPaths assembling algorithm The algorithm developed for RavKav system is a hybrid of 2 well known algorithms: “Dijkstra” for shortest-path finding, “DFS” for a tree scanning and “Δ near-optimal-paths” for an inappropriate paths pruning.
The hybrid algorithm was developed with domain-specific assumptions in mind, which makes the k-shortest-paths problem solvable in reasonable time.
