Incident Response, Parking Management, and Maintenance Management Systems
Incidents Could be anything, outhouses to Christmas trees
Incidents in Washington
Incident Management / Emergency Response Urban legend: 60 percent of delay is related to non-recurring congestion – incidents Solution: –Identify and remove incidents –Speed removal by sending the correct equipment as quickly as possible
Incident Management Incident detection Incident verification Incident response Management Motorist information
Traffic Management Center
Incident Detection Now, primarily by cellular phone –Overwhelming 911 call centers –E-911 (location information) Also –Traffic surveillance systems –CB radio –Motorist call boxes
Motorist Call Boxes Used to be expensive, now easy to install because of cell service
Incident Verification Notification of an incident is not detection Where is it really? What is the problem? Does it really exist?
Incident Verification Usually requires visual confirmation –CCTV –Personal visit Service patrol Police Airplane Maintenance staff
Service Patrols
Incident Verification - Response Verification allows call out of response The faster the proper response, the faster clearance takes place
Level of Response
Incident Response Proper response requires an understanding of the incident –Basic assistance (gas / a push) –Tow truck –Large tow truck –Fire truck –EMT –Hazardous material spill recovery –Fatal accident investigation team (Police use technology to record and clear scene, e.g. photogrammerty)
Incident Response - Management Communications are key –Between respondents –Call for additional assistance –Coordination of efforts Turf wars used to be a big issues ITS provides many new cost effective communication options
Incident Management – Motorist Information Motorist information is a big part of management –Routing information Manage facility demand Provide better travel alternatives to customers Reduce frustration / poor driving behavior –Manage traveler expectations
Motorist Information Information needs to be delivered to customers –Radio –VMS / CMS –New electronic devices –Other
HAR
VMS – CMS
VMS / CMS/ DMS
Parking Management Maximize space utilization (if demand is not evenly distributed) Reduce VMT caused by searching for a space One estimate is up to 30% of urban traffic is “search traffic”
Parking Management Requires –Monitoring of space availability –Communication with drivers –Connection between monitor and communications –Funding to pay for the system
Parking Management Methods for monitoring space availability –Counting in/out movements –Checking individual space availability Communication with motorists (guidance systems) –VMS / CMS (location?) Reservation Systems
Parking Management Message Signs –Where do you place them? At the garage Prior to the garage At decision points –What do they say? Numbers versus directions –How do you update them? –When do they get updated?
Parking Technologies Automated parking systems –Robopark Electronic or wireless reservation/payment –Similar to electronic tolls –Use mobile phone or transponders Advanced parking meters –Provide real time information if space is occupied
Parking Management Who pays for the system? –What’s the incentive to do this? Who participates in the system? Where are the benefits? –The public? –The private parking companies?
EU’s e-Parking Project On-going European Union program Uses wireless networks, cell phones, PDAs to: –Get advance information on parking space –Make a reservation –Open barrier at facility –Pay for service Can all be completed in vehicle

Smart Parking at Baltimore Airport Signs indicate number of free spaces
Ultrasound sensor checks each space for a vehicle. Green/Red light above space indicates if space available.
Green arrows point direct drivers to floors with open spaces
Signs point to open spaces
Open Stall Changeable signs indicate spaces in rows
Robopark Space saving modular parking systems Driver parks and pushes button Car is automatically moved to a space Use access card or code to retrieve car
Seattle Center Parking New system at three parking lots and garages Loops at entrance/exit tally cars and determine occupancy Linked to VMS signs on streets in area
Maintenance Management Real time (predictive) knowledge of weather conditions Real time knowledge of the position and status of assets 22% of vehicle crashes in U.S. occur under adverse road weather conditions
Snow Control / Removal Less expensive to prevent snow/ice accumulation than to remove it Place anti-icing chemicals prior to ice formation –Only saves money if it actually snows / ices over
Snow Prediction Requires extensive weather monitoring system Must track micro-climates Need forecasting capabilities But can be save money
Smart Snowplow Technologies Finding and staying on roads –GPS with accurate road database, magnetic paint strips, embedded magnetic markers Detect hidden objects –Collision warning radar Rear end collisions –Strobes Driver fatigue –Devices designed with driver comfort in mind Friction measurement (for performance info)
