- Explain What factors determine the requirements for traffic control and safety hardware management data collection survey frequencies?As a GIS Analyst how can you minimize road accidents using GIS Knowledge & tools? And Why GIS is termed as the Science of where?As a GIS Analyst how can you minimize road accidents using GIS Knowledge & tools?
- What role does traffic analysis and monitoring play specifically?In your own words, list and discuss the 3 means by which accident locations can be ranked for further investigation, commenting on their advantages and disadvantages over each other.Answer the following: -Based from ICAO, how does the organization define "accident" -How does "accident" different from "incident". Differentiate accident and incident.
- Describe how a continuous control count can be used with a two-day count to estimate Average Annual Daily Traffic (AADT).A rural primary road segment of 2 miles long has an average annual daily traffic(AADT) of 11,350. The number of crashes that have occurred over the past 5 yearsare 5 fatal, 55 injury crashes and 100 property damage only crashes. Statewide averagecrashes for this type of road are 2 fatal, 130 injury, and 300 property damage onlycrashes per 100 MVMT. The weighting factors for fatal, injury and property crashesare 8, 3, 1, respectively. Using the critical crash ratio methodology, determine whetherthis site can be labeled a hazardous site. Use a 95 percent confidence limit.List the primary objectives and different functions of a freeway incident management program. List and describe 5 widely accepted incident detection algorithms.
