Abstract
Navigation systems often aid users when traveling in unfamiliar locations. Current navigation systems tend to focus on identifying the shortest or fastest routes between two points. However, path cost expressed in terms of length and distance (i.e., the utilitarian qualities of travel) is only one attribute which could be used in route recommendation. Recent years have seen navigation systems moving beyond such utilitarian attributes. These include systems aimed at providing users with scenic, safe or attractive routes among other dimensions. In this paper, we contribute to the existing research domain by providing an overview of the different quality-aware route navigation systems that have been proposed in past research for pedestrians. In particular, we examine the different qualities which have been used as key criteria in route recommendation. As the outcome of the paper, we provide a categorization of these systems based on our proposed SWEEP taxonomy. In addition, we outline the various data sources, algorithms and evaluation approaches that have been used to implement quality-aware route navigation systems. Afterwards, we conclude by discussing potential problems encountered in previous studies and highlight promising directions for future research.

Automatic route navigation systems have become an essential tool in modern society for people who wish to navigate in physical spaces, especially within unknown areas
AN OVERVIEW OF QUALITY-AWARE ROUTE NAVIGATION SYSTEMS Based on the identified literature, we provide an overview of the quality-aware route navigation systems which have been proposed based on (1) the attributes which are used to represent the qualities of a route, (2) the type of data features which have been used to implement such systems, (3) the algorithms used to implement the systems and (4) the evaluation approaches used to implement quality-aware route navigation systems
While traditional route recommendation is still based on utilitarian factors such as distance and time cost, there have been an increasing number of systems proposed in recent literature which go beyond helping users find the shortest route and consider other qualities such as safety and well-being
Summary
Automatic route navigation systems have become an essential tool in modern society for people who wish to navigate in physical spaces, especially within unknown areas. Before the advent of Web-based technologies, a common approach in deciding which route to take was to refer to a physical map before or during the travel and the entire trip would generally need to be pre-planned by the travellers. Automatic route navigation systems had begun to emerge and became more popular after the growth of mobile technology and improvements in digital mapping techniques. There are a number of services designed to help users navigate effectively which have been made available to the public. Google Maps in particular which was established in 2005, has grown to become one of the most popular navigation services, helping millions of users find the most cost-effective path towards their desired destinations through driving, public transportation or walking
