"East/middle/west Japan (NEXCO3 company)/JB Motoshi Expressway is Obon [14 days from Thursday, August 5, 2010 to Wednesday, August 18, 2010] Expressway] on traffic congestion prediction and countermeasures.
1 Request for distributed use
- Congestion on the Obon is heavy when the Out-bound line is from Thursday, August 12th to Sunday, August 15th, and on the In-bound it is from Friday, August 13th to Monday, August 16th. I am predicting. (See the figure below)
- This traffic congestion forecast is based on the actual traffic volume increase and traffic congestion conditions that were confirmed during the heavy traffic seasons such as the Bon Festival last year, the year-end and New Year holidays, and this year's Golden Week as the effect of special discounts for holidays.

Comparison of the number of traffic jams with Obon last year [H21: 8/6 (Thurs)-8/19 (Wed) *Including impact of accidents, etc.]
| Traffic jam scale | (1) 2010 Bon Festival | (2) 2009 Bon Festival | Difference ((1)-(2)) | ||||||
|---|---|---|---|---|---|---|---|---|---|
| total | going down | going up | total | going down | going up | total | going down | going up | |
| Number of traffic jams over 10km | 596 times | 230 times | 366 times | 546 times | 218 times | 328 times | +50 times | +12 times | +38 times |
| Number of traffic jams over 30km | 46 times | 17 times | 29 times | 56 times | 28 times | 28 times | ▲ 10 times | ▲11 times | +1 time |
Due to the Tomei traffic closure due to the Suruga Bay earthquake, the number of traffic jams in 2009 was less than expected (704 traffic jams over 10 km).
2 Plan for congestion measures
Based on the situation of congestion forecasts and last year traffic congestion period (GW, Bon Festival, year-end and New Year holidays, etc.), especially severe congestion during the period in which to predict, In-bound speed decrease caution in the slope or the like, the dark by the illumination up of tunnel lighting We are planning to implement measures against congestion, such as alleviating the feeling of pressure and pressure, alerting the rear end of the traffic jam, arranging parking lot organizers at rest facilities, installing temporary toilets, and securing large vehicles.
