"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))
Traffic jam scale	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.
