MULTI-MODAL ROUTING AND NAVIGATION COST FUNCTIONS FOR LOCATION-BASED SERVICES (LBS). IN: URBAN AND REGIONAL TRANSPORTATION MODELING. ESSAYS IN HONOR OF DAVID BOYCE

Abstract

This chapter on multi-modal routing and navigation cost functions for location-based services (LBS) is from a book of essays published in honor of David Boyce for his contributions to the fields of transportation modeling and regional science. LBS are an emerging technology combining information technology, geographic information systems (GIS), positioning technology, intelligent transportation systems (ITS) technology, and the Internet. LBS combine hardware devices, wireless communication networks, geographic information, and software applications that provide location-related guidance for customers. In this chapter, the author provides a use case that uses request and response for routing and navigation services. The author focuses on developing functional forms for providing services for multi-modal routing and navigation services, including the presentation of a feasible set of functional forms. The chapter also addressed issues related to solving the cost functions in a serviceable time, say within 15 seconds, before responding to users, in the hope that this would shed light on the development of heuristic, but efficiency, solution algorithms in the near future.
