Problem Statement

  • Existing technologies on travel time prediction for public transportation are limited and are mainly designed for homogeneous and lane-disciplined traffic conditions that may not perform well in mixed-traffic conditions, especially in highly populated and congested cities
  • In addition, there are challenges in applying deep learning to vehicle travel time prediction, especially in mixed-traffic conditions.

Technology

Method:

  • Data Collection: Receiving a collection of trip data, which includes both location data and timestamp data for multiple trips on a specific route
  • Determining Travel Times: Travel times, the time taken by the vehicle to traverse each segment of the route, are determined for each trip based on the collected data.
  • Creating Travel Patterns: Creates travel patterns for each route based on the travel times collected over a predefined time interval that include information about temporal variation and spatial variation
  • Prediction: Predicting the vehicle travel time during next instance when the vehicle travels in the same route using the travel pattern
  • Temporal variation –Based on how travel times change based on the time of day or day of the week
  • Spatial variation –Based on how travel times vary between different segments of the route, possibly due to traffic or other factors
  • The travel pattern for each route is determined based on input features obtained using visualization method and statistical test
  • The said visualization method comprises heat maps and the statistical test comprises at least one of K-means clustering and Davies-Bouldin (DB) score
  • The invention also discloses a system with  components for data collection, determination of travel times, creation of travel patterns, and prediction having a unit for generating a travel time predicting model.
  • The travel pattern for each route is determined based on similarity analysis and correlation analysis of the different travel times.

Key Features/ Value Proposition

Technical Perspective:

  • Provides a system and  a method for predicting vehicle travel time in route network with non-homogeneous and mixed traffic conditions

  • Use deep learning techniques for travel time prediction based on travel patterns considering spatio-temporal variation for each route thereby enhancing the accuracy, ease and reliability of travel time prediction.

User Perspective:

  • Travel patterns are created can vary, ranging from hours to days, months, or years, depending on the requirements and the level of detail needed for predictions.

  • The system can be valuable in applications like traffic management, route optimization, and transportation services.
