(2008) Influence of road safety on taxi organisational economic stability: A need for proactive change.

This paper compares and investigates single-agent reinforcement learning (RL) algorithms on the simple and an extended taxi problem domain, and multiagent RL algorithms on a multiagent extension of the simple taxi problem domain we created. In particular, we extend the Policy Hill Climbing (PHC) and the Win or Learn Fast-PHC (WoLF-PHC) algorithms by combining them with the MAXQ hierarchical dec...

In this paper, we use data from a survey of taxi drivers in Singapore to test two competing labor supply hypotheses: the standard intertemporal model and the income targeting model, where workers set an earnings target over some short time horizon. The former predicts positive wage elasticities of labor supply, while an extreme form of the latter implies an elasticity of-1. The estimated wage e...

Current navigation services assume wayfinders new to an environment. In contrast, our focus is on route directions for wayfinders who are familiar with the environment, such as taxi drivers and couriers. We observe that people communicate route directions to these wayfinders in a hierarchical and granular manner, assuming some shared knowledge of the environment. These route directions do not f...

ISSN 0817-8542 ISBN 0 642 24203 8 There is a range of preventive strategies that can reduce the risk of assaults on taxi drivers, including technological interventions, training, and policy changes. A combination of technical interventions, including protective screens, Global Positioning Systems, cameras, cashless payment systems, two-way radios, alarms, flashing emergency lights, and policy i...
