CitySprint Fleetmapper use case -Big Data Bootcamp
- 1. Eduard Lazar - CitySprint A geospatial and time series analysis of the CitySprint fleet
- 2. Blue signals a pick-up Red signals a drop-off Sample of how one driver’s journey looks like Used for: • Viewing the base unit of analysis
- 3. Demand heat map Heat map of pickup locations density Used for: • Optimising resource allocation • Identifying areas for potential expansion
- 4. K-means clustering analysis – 40 centres Employed the K-means algorithm to identify clusters of pickup points Used for: • Validating against current service centres map • Identifying areas for potential expansion
- 5. K-means 100 centres Higher granularity clustering Used for: • Assessing the frequency of pickups for micro- clusters (e.g. villages, neighbourhoods) • Directing drivers to hotter waiting areas
- 6. Geographical supply & demand Pickup locations shown vs to routes Used for: • Improving likelihood of parcel pickup while on-route
- 7. 0.0 4.5 9.0 13.5 18.0 0 3 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Expectedparcels Time of day Expected parcels allocated to cluster 41 (Stevenage) Demand variation across time Used for: • Positioning couriers in the right place at the right time For each demand cluster we calculated the frequency of pickups per hour
- 8. The solution outline • Data science capabilities of Spark, easy to use with SQL knowledge • Map plotting on ARGIS – heat mapping, zoom in/out capabilities, real-time • High-performance due to in-memory processing capabilities of Spark • Can work with large data sets due to high performance disk-based data access in Hadoop File System (HDFS) • Can import data from EDW
- 9. Why Bigstep? • Easy to use - Easy to deploy, redeploy, erase and rewind. Easy to experiment with • Big Data Focus – Infrastructure, orchestration, and software ecosystem deliver performance & ease of use for big data • Domain Experts – Extensive hands-on experience in delivering complex big data solutions for multiple verticals & use cases • Consultative Approach – Direct contact and support from experienced big data, devops, and infrastructure specialists • Best In Class Infrastructure – The world’s highest performance cloud

Hinweis der Redaktion
- Objectives: Take geospatial and time series data and make it easily manageable and usable by business users Discover new business insights to optimize operations Run real-time analysis on 22.626.119 records Test if Spark and Hadoop are suitable data analysis tools for CitySprint Design a flexible, versatile environment for analyzing fleet data Implement solution with enough performance so that real time data exploration is possible on the full dataset
- Follows a random driver on a typical day through pickup and dropoff points. Map can zoom in, zoom out
- Shows the hot points of pickup points along the uk. A good overview of the overall dataset.
- Compared against our service center locations it shows a few differences. A clustering algorithm identifies ‘clusters’ of elements by it’s own. K-means needs to be told how many clusters to look for.
- This is what happens if we tell k-means to split the dataset into 100 hot locations.
- The blue dots are actual gps information of en-route drivers. Shows typical routes but only some routes go through hot areas.
- A ‘cluster’ timetable is used to predict demand at a particular cluster on a particular time. Useful to instruct the driver if he is to stay or to go to it’s destination. This can help uberize the business.
- Used a combination of technologies, mostly Spark on Hadoop on Bigstep. Imported data from production Postgres DB via Sqoop into avro and from there via spark into varous CSV files rendered by the ESRI (ARCGIS). Postgres concentrates information from mobile devices.
