Supply and Demand Aware Synthetic Data Generation for On-demand Traffic with Real-world Characteristics
IWCTS'17: Proceedings of the 10th ACM SIGSPATIAL Workshop on Computational Transportation SciencePages 36–41https://doi.org/10.1145/3151547.3151554The on-demand economy has attracted significant attention in recent years, with a rapid growth in on-demand services ranging from ride-hailing to package delivery and grocery pickup. However, real-world spatio-temporal data that can be used for ...

Geographical Huff Model Calibration using Taxi Trajectory Data
IWCTS'17: Proceedings of the 10th ACM SIGSPATIAL Workshop on Computational Transportation SciencePages 30–35https://doi.org/10.1145/3151547.3151553The widely used Huff model is designed to estimate the spatial probability distribution of shopping centre patronage based on a shopping centre's attractiveness and the cost of a customer's travel. Here, we calibrate the Huff model for the city of ...

A Framework for Interactive Geospatial Map Cleaning using GPS Trajectories
IWCTS'17: Proceedings of the 10th ACM SIGSPATIAL Workshop on Computational Transportation SciencePages 19–23https://doi.org/10.1145/3151547.3151551A volunteered geographic information system, e.g., OpenStreetMap (OSM), collects data from volunteers to generate geospatial maps. To keep the map consistent, volunteers are expected to perform the tedious task of updating the underlying geospatial data ...

A 2-Step Approach to Improve Data-driven Parking Availability Predictions
IWCTS'17: Proceedings of the 10th ACM SIGSPATIAL Workshop on Computational Transportation SciencePages 13–18https://doi.org/10.1145/3151547.3151550Knowing where to park in advance is a most wished feature by many drivers. In recent years, many research efforts have been spent to analyse massive amount of parking information, to learn availability trends and thus to predict, within a Parking ...

Data Driven Analysis of the Potentials of Dynamic Ride Pooling
IWCTS'17: Proceedings of the 10th ACM SIGSPATIAL Workshop on Computational Transportation SciencePages 7–12https://doi.org/10.1145/3151547.3151549This paper focuses on the challenge of dynamically pooling multiple ride requests in real time in order to achieve greater overall efficiency for ride sharing/hailing services. A rigorous formulation of this problem and an efficient pooling method is ...

Temporal Sampling Constraints for GeoSpatial Path Reconstruction in a Transportation Network
IWCTS'17: Proceedings of the 10th ACM SIGSPATIAL Workshop on Computational Transportation SciencePages 1–6https://doi.org/10.1145/3151547.3151548In this paper, we address the problem of recovering traveled geospatial paths on a transportation network from time sampled location traces. Determining the proper sampling rate for path reconstruction has not traditionally been addressed ahead of the ...
