• 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

• 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)
![Page 19: Handheld Computing Devices for Mobile Traffic Records Management](https://reader034.vdocuments.us/reader034/viewer/2022051517/56814ac9550346895db7de83/html5/thumbnails/19.jpg)
Voice LETSVoice LETSVoice LETSVoice LETS
• 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

Voice LETS PlatformsVoice LETS PlatformsVoice LETS PlatformsVoice LETS Platforms
• 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

• 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
