CEE 320 Spring 2007 Intelligent Transportation Systems (ITS) CEE 320 Steve Muench

CEE 320 Spring 2007 Outline Need for traffic solutions Possible solutions Intelligent Transportation Systems

CEE 320 Spring 2007 Road Use Growth From the Bureau of Transportation Statistics, National Transportation Statistics 2003

CEE 320 Spring 2007 Changes in Congested Peak-Period Travel

CEE 320 Spring 2007 Problems Caused by Congestion Increased… –Travel time –Travel cost –Air pollution –Accident risk

CEE 320 Spring 2007 Options Construct new roads –Covered in geometric design –Not likely to happen on a large scale Reduce Traffic –Travel demand management –Alternative transportation Increase existing infrastructure capacity –Uses intelligent transportation systems (ITS)

CEE 320 Spring 2007 Construction Is Part of the Solution

CEE 320 Spring 2007 Option 1: Construction Highway Construction Cost Sampling ProjectTotal CostLane-Miles Cost per Lane-Mile Route 3, North Boston$395.0 million42$9.4 million I-4 Tampa to Orlando$403.0 million73$5.5 million I-5 Oregon $30.0 million5.16$5.8 million US 26 Sunset Hwy. Oregon$10.6 million2.24$4.8 million US 12 near Walla Walla River$36.4 million25$1.5 million US 101 on Olympic Peninsula$1.8 million0.8$2.2 million General Conclusion Highways cost $1 to $10 million per lane-mile to build

CEE 320 Spring 2007 Option 3: Increase Existing Infrastructure Capacity An alternative to expensive new highway construction is the implementation of strategies that promote more efficient utilization of transportation infrastructures. These strategies are known as the Intelligent Transportation Systems (ITS), which aims to reduce travel time, ease delay and congestion, improve safety, and reduce pollutant emissions

CEE 320 Spring 2007 Highway Capacity Full Capacity How Much Capacity Is There?

CEE 320 Spring 2007 Incidents: more delay is caused by incidents than by recurring peak period congestion. Highway Capacity Remaining Effective Capacity How Much Capacity Is There? Incidents can comprise 50% of peak period congestion. 1 min delay in clearance = 4 to 5 min of traffic backup.

CEE 320 Spring 2007 Work zones: major cost is delay imparted to the traveler Incidents: more delay is caused by incidents than by recurring peak period congestion. Highway Capacity Remaining Effective Capacity How Much Capacity Is There? Caltrans reports 20% of freeway centerline miles are under construction.

CEE 320 Spring 2007 Work zones: major cost is delay imparted to the traveler Incidents: more delay is caused by incidents than by recurring peak period congestion. Highway Capacity Remaining Effective Capacity How Much Capacity Is There? Weather: Snow, fog, rain can all restrict capacity 75% of NHS is subject to snow & 100% is subject to rain.

Highway Capacity Remaining Effective Capacity How Much Capacity Is There? Weather: Snow, fog, rain can all restrict capacity Special events and disasters further restrict capacity Periodic events can cause further restrict capacity.
