AGE	https://dev.to/xk_woon/become-a-traffic-wizard-a-beginners-guide-to-routing-traffic-with-apache-age-1kg6	Become a Traffic Wizard A Beginner x s Guide to Routing Traffic with Apache AGE IntroductionTraffic routing refers to the process of directing users from one destination to another to form a path You may be familiar with it from route directory in maps and also from networking which is the backbone of how the internet works by requesting to the appropriate server or resource in a distributed computing environment Apache AGE is a powerful open source graph database software that can be used also used to route traffic However for beginners it can be overwhelming to know where to start with Apache AGE That is why I ve put together this comprehensive guide to help you become a traffic routing wizard using Apache AGE In this blog post I will cover the basics of traffic routing for optimizing a routing configuration Whether you re just starting out or you re looking to improve your existing skills this guide has something for everyone So let s dive in and learn how to route traffic with Apache AGE BackgroundFor this guide I ll be using the SkyTrain lines in Vancouver as our example dataset The SkyTrain is a rapid transit system that serves the Metro Vancouver area in British Columbia Canada The system consists of three lines and stations where stations are served by the Expo Line by the Millennium Line by the Canada Line by both the Expo and Canada Lines and by both the Expo and Millennium Lines The SkyTrain is a popular mode of transportation for commuters and tourists alike and it s important to find out the most efficient route in order to cut costs and time Skytrain and Seabus Map Image source To set up the data for the SkyTrain system we ll need to create a dataset that contains information about each station and the connections between them This dataset will include nodes for each station and relationships between the nodes to represent the connections between stations By using the SkyTrain system as the example dataset I will demonstrate how to set up data for a real world traffic routing scenario This will allow you to apply the concepts and techniques you learn to your own projects whether you re working on a transportation system a web application or any other distributed computing environment Setting Up the DataLet s first create a new graph to work with We can do this by the following command SELECT create graph SkyTrain A graph called SkyTrain has been newly created Now we would like to create nodes and relationships to match the connections from the transit map The CREATE clause will be used to do this SELECT FROM cypher SkyTrain CREATE tss Station name nd Street line Expo tna Station name th Avenue line Expo abd Station name Aberdeen line Canada bra Station name Braid line Expo btw Station name Brentwood Town Centre line Millennium bgp Station name Bridgeport line Canada bch Station name

variable as the stations may belong to more than one type of line Aliases are given to each node which are used to set the relationships between the stations with Route labels consisting a time property Exploring the DataNow that we have successfully created and set up our graph let s explore the information we can retrieve from the data Using the following query will display all the names of the existing stations SELECT FROM cypher SkyTrain MATCH n Station RETURN n name AS station agtype All station names should be outputted If not check that you have created the nodes and relationships correctly Don t worry if you are encountering issues run the query SELECT FROM cypher SkyTrain MATCH n DETACH DELETE n AS a agtype to remove all nodes and relationships and then try setting up the data again by copying and pasting the query from the previous section To view station names from specified lines run the following query SELECT FROM cypher SkyTrain MATCH n Station WHERE Canada IN n line RETURN n name AS station agtype You will be able to view the station names that belong to the Canada line Add the AND clause to further filter the results for example replace the line with the WHERE clause to WHERE Canada IN n line AND Expo IN n line and you will see that only the Waterfront station gets outputted To check which station connects to another run the following query SELECT FROM cypher SkyTrain MATCH a Station r Route b Station RETURN a name r time b name AS station from agtype time agtype station to agtype Three columns will be displayed showing the station names from and to one another with the time it takes to travel between You might notice that there are duplicates going to and from stations as the query ignores the direction of the relationships which is the favoured option in this case as a train is able to go back and forth between stations in practice Finding the Optimal PathThe optimal path in this case will be defined as the most time efficient path The path with the least total travel time would be the desired selection Running the query below will show all the paths available from Richmond Brighouse station to Lafarge Lake Douglas station SELECT FROM cypher SkyTrain MATCH paths a Station name Richmond Brighouse Route b Station name Lafarge Lake Douglas WITH paths relationships paths AS rels UNWIND rels AS rel WITH nodes paths AS path collect rel time AS times sum rel time AS total time RETURN total time times path AS total time agtype times agtype path agtype ORDER BY total time The query searches for connections from a starting point to an end point in this case from Richmond Brighouse station to Lafarge Lake Douglas station and saves the information into a variable called paths The relationships contained in the variable is stored into another vairable rels The UNWIND clause removes the inner arrays from rels and splits them into different rows of the output which can be referenced as rel The nodes in the path is saved into path the time of each route is saved into times and the total travel time is saved into total time which then are returned to be displayed in the final table Here is what the output should look like total time times path id label Station properties line Canada name Richmond Brighouse vertex id label Station properties line Canada name Lansdowne vertex id label

Millennium name Inlet Centre vertex id label Station properties line Millennium name Coquitlam Central vertex id label Station properties line Millennium name Lincoln vertex id label Station properties line Millennium name Lafarge Lake Douglas vertex rows There are different routes in total that can be taken From this information we can deduce that the optimal path takes minutes using the Canada line until Waterfront station exchanging to the Expo line until Commercial Broadway station and finally exchanging to the Millennium line until the final destination Efficiency may depend of different factors whether it be cost number of line exchanges made and so on Play around with the conditions to fit your specifications and see which path is the most efficient in terms of your definition Visualizing the DataIn this section we will utilize AgeViewer to visualize the graphs that we have created in order to better understand the data Let s first view our entire map using the following query SELECT FROM cypher SkyTrain MATCH n r m RETURN n r m AS n agtype r agtype m agtype The displayed graph may initially show an unorganized view of the nodes and relationships however by changing the layout options or dragging each node to a specific position manually we are able to better organize them For this example I have used the Klay layout to view the path in a straight line To view station names and their connections from specified lines run the following query SELECT FROM cypher SkyTrain MATCH n r m WHERE Canada IN n line RETURN n r m AS n agtype r agtype m agtype You should get a graph similar to the one below Just like in the Exploring the Data section you will be able to view the station names that belong to the Canada line this time along with their connected routes Add the AND clause to further filter the results for example replace the line with the WHERE clause to WHERE Canada IN n line AND Expo IN n line and you will see that only the Waterfront station and its connections get outputted Finally running the query below will show the most optimal path from Richmond Brighouse station to Lafarge Lake Douglas station SELECT paths relFROM cypher SkyTrain MATCH paths a Station name Richmond Brighouse Route b Station name Lafarge Lake Douglas WITH paths relationships paths AS rels UNWIND rels AS rel WITH paths AS paths rel AS rel collect rel time AS times sum rel time AS total time RETURN paths rel times total time AS paths agtype rel agtype times agtype total time agtype ORDER BY total timeLIMIT This query is slightly altered from the previous query in the Finding the Optimal Path section The relationships are included in the output this time and only the top row of the result is chosen as it will be the most time efficient path As you can see this graph visualization is much clearer than the table result and you can easily tell the path of the routes Go ahead and try out your own queries and with your own data as well to apply the knowledge you have learnt That is all for the basics of route trafficking in Apache AGE ConclusionIn this guide we ve explored how to route traffic using Apache AGE We began by discussing the importance of setting up data that is relevant to a practical application and used the SkyTrain system in Vancouver as an example dataset We then walked through the steps involved in setting up the data including creating nodes for each station and relationships between them to represent the connections between stations Finally we looked at different methods on producing and visualizing tables and graphs that will be of use upon deciding on the most optimal path With the skills and knowledge you ve gained from this guide you ll be well equipped to take on any traffic routing challenge that comes your way Start using Apache AGE today and become a traffic routing wizard	2023-04-09 22:11:26
