## Task 6:  Telematics 

**Objective: Determine distraction potential for commonly-used telematics functions.**
**Staffing: **
**6a: Green (1.0), Shah (3)**
**6b: Kantowitz, Premakur, Sullivan**
**Deliverables**
**Literature review (fall, 2003)**
**Task 6 report (Jan, 2004)**
**Schedule**
**Literature review (Aug, 2003)**
**Design simulator study (Sept, 2003)**
**Data collection (Nov-Dec, 2003)**
**Report (Feb-March, 2003)**

## Task 6a:Telematics Demand Lit. Review

**    ****Issues:**
- What is the distraction potential of various telematic functions?
- Note: The measures of interest are task time, the number of glances required, and the mean time per glance.

##     Activities:
Examined 30-40 papers of which 15-20 are useful. Summarized about 15 papers on the topic.  List of the key measures by task (e.g., destination entry) is being compiled. 

Some key documents so far:
Kurokawa’s dissertation
Green (1999) tech report
Blanco’s thesis
Gallagher’s dissertation
Curry, Greenberg, and Glanco (2002) TRB paper

## Task 6a:Telematics Demand Lit. Review

**Information in summaries**
-  study authors and year
-  objectives
-  method (road types, time of day, vehicle)
-  subjects (number, ages, gender)
-  in-vehicle tasks
-  independent measures
-     (task type, road, traffic, age, etc.)
-  dependent measures
-     (mean glance time, steering wheel  velocity,
-     number of errors, etc.)
-  findings

## Task 6a:Telematics Demand Lit. Review

** ****Activities to be done:**
- 1. Explore link between RT and other measures in the literature.
- 2. Identify measures in current guidelines (SAE J2364, AAM, etc.)
- 3. Examine IVIS Demand model for task key task characteristics (visual, auditory, cognitive, manual, and auditory demand)

## Task 6b:Telematics

**Objective: **
**Identify the distraction/workload associated with common telematic functions by measuring driver performance and brake RT in a simulator**
**Activities:**
**Develop driving world and driving scenarios for UMTRI Simulator, using tiles from Tasks 2 and 5**
**Develop telematics secondary tasks, possibilities include:**
** ****Generic telematic visual choice-reaction task (Kantowitz, 1995; Harms & Pattern, 2003)**
**Specific telematic tasks TBD based upon results of Task 6a**
**Dependent variables include the same measures of driving performance studied in Tasks 2b and 5b such as brake RT and steering behavior**
**Independent variables include telematic secondary tasks**
**Pilot study (a few subjects)**

## Task 6b:Telematics

**Activities:**
**Experimental study **
**16 subjects age 35-55; 16 subjects age 18-25**
**Practice driving using “square world” from Task 2b or equivalent from Task 5b**
**Single-task practice on secondary telematic tasks**
**Baseline driving data**
**Test using “zig-zag world” from Task 2b or equivalent from Task 5b with telematic secondary tasks**
**Issues/Concerns**
**Task 6b depends upon timely and successful results from Tasks 6a, 2b and 5b.  Delays or incomplete solutions for these tasks will delay Task 6b.**

## Task 6b:Telematics

**Activities:**
**Expected results**
**Driver performance should decrease for high loads of secondary task.  There may be trade-offs between driving and secondary tasks which makes inclusion of appropriate single-task control conditions imperative.  There is no universal secondary task so that potential interactions with driving may vary across different telematic functions (Kantowitz & Simsek, 2000).**
