Our ProjectsOur ProjectsOur ProjectsOur Projects

• CARE is our primary product – Critical Analysis Reporting Environment– Supports the analysis of crash data

• Produce planning documents, reports and studies– Alabama Crash Facts Book (since 1998)– Alabama and North Carolina Highway Safety Plans– Special studies (http://care.cs.ua.edu)

• Work with general law enforcement information systems– Crash Form Entry System – E-Citation System – Law Enforcement Tactical System (LETS)– Model Integrated Defendant Access System (MIDAS)

• Saving lives since 1982….• Historical summary:

– CARE: Originally a front end to SPSS– Evolved to a separate Windows-based product– Basic analysis functionality also over the Web– Location analysis and roadway geometrics – Won NHTSA Administrator’s award in 1995– Current or past contracts with eight states:

• AL, DE, IA, FL, MI, NC, TN

– Negotiations ongoing with 2-3 other states

• Allows access to crash data• Several analysis techniques:

– Frequency distributions– Cross-tabulations– Crash rates per population size (ACT)– Location analysis (variety of techniques

here)

• Information Mining (IMPACT)

Crash Form Entry SystemCrash Form Entry SystemCrash Form Entry SystemCrash Form Entry System

• Supports automated data entry onto a crash form from an in-car laptop– Includes support for drawing collision

diagrams (Easy Street Draw)• Also fully functional on a tablet PC• Some data can also be entered via a PDA

– Wireless communication from PDA to the laptop

– PDA contains a built-in scanner for scanning driver’s license bar codes

E-Citation SystemE-Citation SystemE-Citation SystemE-Citation System

• Citation data may be entered via:– Laptop– Tablet– PDA and transmitted to the laptop over a wireless

network• Project: E-citation for commercial truck

enforcement in Alabama (MCSAP)– Funded by FMCSA

• Status: Pilot was initiated at the Heflin Weigh Station in January

• Full rollout to the entire MCSAP unit scheduled by mid-2004

• Web-based system• Integrates a number of state databases (driver license,

driver history, warrants, etc.)• Allows the look-up of an individual by name,

characteristics, etc.• Returns personal information about the individual• Deployed in January 2003• Lots of early success stories• Approximately 4000 registered users in AL.

• Databases are being added regularly– Pardons and Paroles– Court Cases– Prison Census– Death Certificates– SmartCOP data– Jefferson County mugshots

• Longer term issues:– User interface improvement– Mobilization– Fuzzy searches– Virtual lineups– Integration among other states’ data

• Funded by NHTSA to track impaired drivers• Web-based system• DUI arrests are routed through the court

referral (CRO) system• MIDAS provides a statewide system for

CROs to use:– Recording and accessing case history

information– Information available for statewide sharing

Wireless ProjectsWireless ProjectsWireless ProjectsWireless Projects

• Designed to migrate our non-wireless apps to a mobile environment:– WLAN extensions to crash entry and E-citation

systems– Wide area mobile E-citation– Voice-based crash entry and E-citation– Mobile LETS

• Also for infrastructure support:– Mobile data capture devices– Wide Area Data Communications

• Crash form entry and E-citation: Base systems operate on laptops

• Need to be able to walk around and capture data

• Current system:– Supports “satellite” PDAs– Master application runs on laptop in the

car

• Phase II of E-citation project:– Currently deployed at weigh station (fixed

location)– Must now deploy in cars (mobile setting)– Must deal with mobile data comm. issues

• Our strategy:– Communication-independent architecture– We support:

• Dial-up• Cellular• 802.11• Wired LAN connection

• Prototype project with Auburn Center for IMPACT

• Presentation forthcoming in this session

• Need to make LETS more useful in a mobile officer setting

• Issues:– Streamlining interface to reduce bandwidth and information

overload– Dealing with intermittent or no mobile connectivity

• Two separate efforts underway:– Voice LETS (voice recognition)– Mobile LETS (streamlined interface and/or local data)

• Another joint effort with Auburn IMPACT center• Basic idea:

– Speak input information– Receive output information via voice or in silent mode to

data screen

• Really a LETS subset to look up a specific individual:– Speak SSN, license ID, tag #, name/DOB– Physical description of individual or vehicle read back

• Phone (cellular or land line)• Computer (using Voice over IP to

connect to server)• Radiophone (in experimental stages)• Prototypes exist of all three platforms• Current emphasis:

– Scaling phone prototype to statewide production system

• Conducting feasibility study right now• Two emphasis areas:

– Streamlined user interfaces using a variety of ubiquitous computing devices (e.g., cell phone screens)

– Off-loaded data onto local laptop or tablet PC to deal with limited connectivity issues

• Will likely lead to two separate products:– LETS GO: Laptop-based with local data and some

kind of update paradigm– LETS Lite: Streamlined interface for ubiquitous

computing devices

• Would like to be able to work with small handheld devices.

• PDAs had both programming and performance problems.

• Our goal in this area: Obtain a small handheld device suitable for this mission, with acceptable performance.– Based on the Microsoft Tablet PC

Tablet PCsTablet PCsTablet PCsTablet PCs

• Currently working with some of the larger tablet PCs.

• Would like to migrate to a small PDA-sized tablet as they become available.– Oqo: http://www.oqo.com

• May be useful to build a sleeve for this device to hold various peripherals to support:– Voice input (on-board)– Bar code scanning– Electronic signatures– Video camera– GPS

• Added functionality (peripherals):– Bar code scanner– Mag stripe scanner– Camera– GPS

• Peripheral – Oqo unit connections options include:– Building a sleeve for the Oqo and embed peripherals– Removing the processor and contents from the current Oqo

box and build a new physical box for the product• Communications:

– Cellular PCMCIA card– Connected cell phone– Bluetooth to a separate cell phone

• Support to keep mobile law enforcement connected.• Currently experimenting with several possibilities:

– Cellular– Wi-fi

• We are comparing these two (and other) technologies:– Plans to develop a community-based wi-fi network in one

or more Alabama cities for use by law enforcement– This network can ultimately be shared between law

enforcement and researchers exploring wireless issues

• Looking to combine with other efforts to provide statewide and regionwide coverage
