MODELLING TRANSPORT FOR LONDON'S ITS DATA DEMANDS AND THE REQUIRED CAPACITY OF A WLAN SYSTEM

摘要

This paper considers the data demands for ITS applications used by TfL' and how this demand can be met using WLAN-enabled file transfers. It provides: an analysis of AP deployment densities for WLAN access points to meet specified QoS figures; and overvie overvieww recommendations for deployment and control strategies for bandwidth-hungry CCTV applications. Data demand analysis is based on statistical distribution models' populated with the results of file transfer demand surveys compiled from sources in TfL and Llondon ondon bus operators. ITS data considered includes: vehicle operational data; vehicle location logs; CCTV footage downloads; and bus-mounted traffic enforcement camera footage.
