Comparison of the number of traffic jams with the Golden Week period of the previous year
| Traffic jam scale | 2018 Friday, April 27 to Sunday, May 6 | 2017 Friday, April 28 to Sunday, May 7 | |
|---|---|---|---|
| Number of predictions | Total traffic count | Number of traffic jams due to traffic concentration (*) | |
| 10km or more | 114 times | 109 times | 96 times |
- The number of traffic jams due to traffic concentration is the number of traffic jams excluding the impact of accidents, etc.
2 Measures to counter congestion
Based on the current traffic congestion forecast and the traffic congestion period until now (year-end and New Year holidays, Obon, Golden Week, etc.), we will implement the following efforts during the period when we predict particularly heavy congestion. Attachment 2 [PDF: 348KB]
- Initiatives in the main line
-In-bound rear-end collision Beware of speed decrease caution, traffic jam end in slope, etc. - Efforts at rest facilities
・ Arrangement of parking lot organizers ・ Secure large vehicle parking lot ・ Install temporary toilets, etc.
- Expressway information of packed "Drive Plaza (DraPla)" Attachment 3 [PDF: 848KB]
NEXCO EAST "is to provide DraPla In", Expressway other provision of real-time road traffic conditions and congestion prediction information, Expressway offers a search service of the required time taking into account the fees and congestion prediction. You can view it from your computer, smartphone or tablet. Please use all means.
・ DraPla - Congestion forecast guide / congestion forecast & outing guide
A traffic congestion forecast guide containing traffic congestion forecasts for NEXCO EAST and Central Japan (Chubu) is distributed in the service area and parking area.

3 Application of ETC holiday discount
Three days discount on ETC holiday discount (rural area) is applied during the Golden Week period from April 28 (Sat) to 30 (Mon), May 3 (Thu) - 6 (Sun).
4 Requests for alleviating traffic congestion
A little effort from customers will help alleviate traffic congestion. Thank you for your cooperation.
- In-bound attention to the rate of decrease in the slope
In-bound in a place that is alerting the slowdown, such as slope, for your cooperation to speed recovery! - Do not reduce the distance between vehicles too much
Ensure sufficient inter-vehicle distance so that you do not press the brakes while driving! - Do not change lanes
Excessive lane changes during traffic jams will worsen traffic congestion!
Topics 1 CA Tokyo Wan Aqua-Line Expressway Traffic Congestion
Tokyo Wan Aqua-Line Expressway, the traffic volume increases year by year due to the rate discount for ETC vehicles (from August 2009) and the opening of large commercial facilities (from April 2012), and it is constant on weekends. There is a traffic jam. Among them, toward the Kawasaki area from Kisarazu In-bound aqua tunnel of the line is In-bound speed is reduced in less notice from the fact that is a hill, has led to the occurrence of congestion. In such areas, we have installed pacemaker lights on the walls to prevent speed reduction.
As a result, 2016 is the traffic jam from the previous year were down, 2017 has been an increase in the traffic jam from the previous year because it is followed by an increase in traffic volume, even in this year's Golden Week period, In-bound in line 4 It is predicted that a long traffic jam of about 15km will occur from 29th (Sun) to 30th (Mon) of the month and 3rd (Thurs) to 5th (Sat) of May.
We know that the peak day of congestion last year during Golden Week took about 50 minutes longer than when there was no traffic. Please cooperate in avoiding the traffic hours when it is predicted to be congested (In-bound lines from around 14:00 to 20:00).
Also, since November of last year, we have been conducting traffic congestion forecasting, “AI traffic congestion prediction,” utilizing NTT DoCoMo's AI technology. Since forecasts are based on the number of people on the day, it is possible to make highly accurate forecasts that take into account the effects of weather and events. Please use it when you go to Boso Peninsula by Aqua Line.
Topics 2 Comparison of time required for route selection
～ Analysis result by ETC2.0 probe data ～
- Due to the development of Expressway, multiple routes can be selected even at the same starting and arriving points.
- Using the section from the Takasaki IC area to the Kawaguchi JCT area as an example, we analyzed the average time required for the customer's route selection last year using ETC2.0 probe data.
- As a result, due to traffic congestion on the Kan-Etsu Expressway, In some cases, the time required for the route via the Northern Kanto Expressway, which has a long mileage, was about 40 minutes shorter.
- Please check the latest traffic conditions from information boards on Expressway, wide area information monitors of rest facilities such as service areas, "DraPla * 1" provided by NEXCO EAST, and select routes. In addition, please use the traffic congestion forecast and leave with plenty of time.
