  1. Platohed, thanks for the detail and logical explanation. i would never understood this table and nobody could explain it better that you did. I assume you are planning to take Transportation this Friday. If it is, good luck to you. You seems very well prepared and smart enough to pass it. I have been trying few times, know a lot of stuff, but can't brake this wall for some reason. Will try this time again. :tardbang:
  2. Platohed, thanks, it does make sense. that is probably the only answer to this problem. Do you know in what case should I use tbl.9-19. Can't figure out the difference between tables. Actually, do you think, if radius is not given in tbl.9-19, I should go to to tbl. 9-31. Or its a different case
  3. Can somebody explain this problem, please What is the difference between exh. 9-19 and 9-31 Green Book Problem: Have typ. 48' intersection (2 lane (12') each direction). No shoulder or parking lines Simple curb radius (no tapers) WB-50 design vh. Question: Considering multiple maneuvering types, the minimum curb radius needed to prevent encroachment into the opposite lanes for the given vehicle is most nearly: A) 50 ft B) 30 ft C) 20 ft D) 40 ft Answer: (which I can't accept or understand) Using Exh. 9-31, pg 615 of the Green Book - need both maneuvering types to be < or = ft (with of two lanes) This requires the curb radius R= 40 ft (answer D)
  4. Dexman PE, this is the best comment I ever read on this site. Unfortunaly, I passed all 6 phases last time and now in phase #5. Is it too early for this phase yet ?
  5. I afraid to say "I nailed it". Last October I really nailed it, had only 9 unknown for the entire test. Everything was straight forwarded and clear. I failed it. Last Friday I had more unanswered questions (about 15 or less total). So, what my chances are? We'll know in 2 month :beat:
  6. Miloc, that is exactly what I have. You can see L2 shown on revision page. Can't help more. Good luck for tomorrow
  7. see p. 5-32 fig. 5.24. This page was revised. See revisions for this page.
  8. It depends of how strong you are in other areas. 8 questions could make the difference.
  9. look carefully for the wording. It should say injure or property or all accident counts. Wording is the key
  10. If it ask to find injury accidents, do not include property damage accidents in you calculations (such car crash)
  11. YES, I had problem like this. you need to choose the highest volume number in traffic direction, or if you asked for entire intersection you need to choose the highest volume for both directions. Like SB is 200,300,400 (3 ph), NB 100, 200,300 (3ph), EB 100,100 (2ph) and WB 100,200 (2ph), So, your V=400+200=600.
  12. I came across problems where eq. 410.15 from Goswami more useful. I think, if they don't ask for Webster formula, we need to use the one from Goswami.
  13. If you given grades, you can find K=L / A. Use Green Book p. 270-277. you can find K-value, base on the tables from Gr. Bk or graphs in CERM p.78-14. Knowing V and K you can find L or SSD
  14. Use Sb=V12 - V22/ 30 (f-g) , Where V is mph,Sb is distance, f is 11.2/32.2=0.35 See CERM p. 74-5. I do not have ITE, but Goswami p.655 describe the case.
