§Two-pronged
approach used to accommodate scale and timing of demo:
□Analyze data from small-scale demo conducted on I-5
Corridor in Seattle
□Supplement small-scale demo results with results from a
simulation testbed (US 101 NB in San Mateo County, CA)
that will model the prototype applications
§Identified
Performance Measures
□Shockwaves, queues, throughput, speed variance, average
travel time, reliability, emissions, safety
□Identified proxy measures for safety: speed variance and
shockwaves
§Developed
Experimental Plan to answer key research questions
□Developed testable hypotheses associated with each
research question
□Identified realistic operational conditions
observed for US 101 NB in a year
□Developed simulation experiments for each
hypothesis
□Examined only SPD-HARM in US 101 NB:
–Q-WARN not modeled since
inadequate information on how drivers respond to advanced
information of queues
§Conducted
simulation model runs, processed results
□Preliminary results available from simulation
analysis
□Will supplement results with
small scale demo results, when available
