Freeways

CS410/510: Cloud and Cluster Data Management

Project Goal and Description:

The goal of this project is to design and implement a small Freeways system using data from "Multimodal Test Data Set Clean-up for Portland Oregon Metropolitan Region", and using NoSQL database. We used Cassandra NoSQL database in this project. In this project, we designed and implemented four queries that help in performing different operations on the Freeways' systems. The implemented queries are:

- Count high speeds: By founding the number of speeds > 100 in the data set
- Find the total volume for the station Foster NB for Sept 21, 2011
- Single-Day Station Travel Times: Find travel time for station Foster NB for 5-­‐minute intervals for Sept 22, 2011. Report travel time in seconds
- Route Finding: Find a route from Johnson Creek to Columbia Blvd on I-205 NB using the upstream and downstream fields

This project is a part of "CS410/510-Cloud and Cluster Data Management" in Portland State University (PSU).

Needed Software:

  • Cassandra 2.0.14
  • Java 6, 7 or 8
  • Eclipse

Using the Application:

  • To run the application using Eclipse:

    1. Setup Cassandra by following the instructions in this URL: http://wiki.apache.org/cassandra/GettingStarted
    2. Create a keyspace and column families using CreateSchema.java file
    3. Upload the data into the tables using SSTableBuilder.java, COPY command or insert statements. (The following files contain the data: detectorid.csv, firstdetector1.csv, firstdetector2.csv, speed.csv and station_loopdata.csv)
    4. Download the GitHub project and import it in Eclipse. (Main files are: CassandraConnector.java, CreateSchema.java, FindRoute.java, QueryHighSpeed.java, QueryTravelTime.java, QueryVolume.java and SSTableBuilder.java)
    5. Add the needed libraries, which are:
    • junit-3.8.1.jar
    • com.datastax.cassandra-2.0.1.jar
    • net.sf.supercsv-2.1.0.jar
    • org.apache.cassandra-2.1.3.jar
    • org.apache.thrift-0.9.2.jar
    • org.apache-extras.cassandra-jdbc-1.2.1.jar
    • org.apache.cassandra-2.1.5.jar
    • org.apache.cassandra-2.1.5.jar
    • org.slf4j-1.7.12.jar
    • org.slf4j-1.7.12.jar
    • log4j-1.2.17.jar
    • org.antlr-3.2.jar
  • To run the application using the .jar file (without using Eclipse)

    1. Download Freeways.jar
    2. Run the .jar file using this command in Terminal: java -jar Freeways.jar

This system is designed and developed by:

  • Kamakshi Nagar
  • Muna Alfahad
  • Renu Thottan
  • Srividya Sundaram
