# Developing and Deploying a Taxi Price Comparison Mobile App in the Wild: Insights and Challenges

## TL;DR

This paper presents the development and deployment of OpenStreetcab, a mobile app for real-time taxi price comparison in London and New York, analyzing market heterogeneity, pricing, and journey time tradeoffs between Uber and local taxis.

## Contribution

It introduces OpenStreetcab, a novel app for comparing taxi prices in real time, and provides empirical insights into market heterogeneity, pricing strategies, and driver navigation advantages.

## Key findings

- Large heterogeneity in taxi markets across cities.
- Uber and local taxis show distinct price and time tradeoffs.
- Experienced drivers navigate faster, especially in dense urban areas.

## Abstract

As modern transportation systems become more complex, there is need for mobile applications that allow travelers to navigate efficiently in cities. In taxi transport the recent proliferation of Uber has introduced new norms including a flexible pricing scheme where journey costs can change rapidly depending on passenger demand and driver supply. To make informed choices on the most appropriate provider for their journeys, travelers need access to knowledge about provider pricing in real time. To this end, we developed OpenStreetcab a mobile application that offers advice on taxi transport comparing provider prices. We describe its development and deployment in two cities, London and New York, and analyse thousands of user journey queries to compare the price patterns of Uber against major local taxi providers. We have observed large heterogeneity across the taxi transport markets in the two cities. This motivated us to perform a price validation and measurement experiment on the ground comparing Uber and Black Cabs in London. The experimental results reveal interesting insights: not only they confirm feedback on pricing and service quality received by professional drivers users, but also they reveal the tradeoffs between prices and journey times between taxi providers. With respect to journey times in particular, we show how experienced taxi drivers, in the majority of the cases, are able to navigate faster to a destination compared to drivers who rely on modern navigation systems. We provide evidence that this advantage becomes stronger in the centre of a city where urban density is high.
