Document Summary
Total volume over a time period, q. System optimal min t = t 1 x 1 + t 2 x 2. Steps: division of geographic region into traffic analysis zones with centroids. Traffic analysis zones homogenous area in terms of land use, socioeconomics. Centroid point chosen as the origin/destination of a traffic analysis zone: graphical representation of real network. Each with associated performance function to compute traffic flow. Nodes intersections or location of change in capacity: determination of trips between each origin-destination pair. Determine trips between zones at peak hours. Use of trip generation and mode/destination choice models. Determined for each link based on assumptions (ex: user equilibrium: determination of traffic flows. World 1. 2 million killed/year with 65% predicted increase by 2020, 50 million injured/year. Canada (2004) 3000 deaths, -25 billions in losses. Less populated & stable weather easier for autonomous vehicles, less inputs to react to. Scanning through images & radar can be affected by luminosity & precipitations.
