On May 9th, NEXCO EAST (Chiyoda-ku, Tokyo, President and Chief Executive Officer: Keiichi Inoue) announced the "Traffic conditions on the Expressway during Golden Week (flash report)", but during the period (April 26 (Wed. )-May 7th (Sunday) for 12 days) We have summarized the results of a detailed examination of traffic congestion mitigation measures.

1 Congestion mitigation effect by providing congestion prediction information

(Detail is Here )

NEXCO EAST provides traffic congestion prediction information through the "Traffic Congestion Prediction Guide" and the Expressway information site "DoraNavi" to help customers avoid traffic congestion and drive comfortably.

The number of traffic congestion of 10 km or more during the period increased by about 6% from the same period last year due to the increase in traffic volume used, but it will be homecoming and returning from tourist destinations In-bound line, traffic congestion was dispersed from May 4th (Thursday) to 6th (Saturday), so a particularly long congestion of 30km or more was halved compared to the previous year., The amount of traffic congestion, which indicates the size of traffic congestion, decreased by about 30% Did.

The distribution of this traffic jam was based on a weekday arrangement that makes it easy to take consecutive holidays from May 3 (Wednesday) to May 7 (Sunday) this year, and "The peak of the In-bound line is May 4 (Thursday). 5th Friday" A customer who viewed the traffic congestion prediction information avoided the traffic congestion and used the Expressway This is also a factor.

We will continue to promote traffic congestion countermeasures and provide detailed traffic congestion forecast information promptly. Please continue to use it for your travel planning.

2 Congestion alleviation effect associated with the use of the ETC time zone discount system

(Detail is Here )

The ETC usage rate in our area during the period was 50% (about 13.59 million units/day), which is about 1.5 times the same period last year (33% [national ETC usage rate]).

An analysis of changes in traffic volume and the occurrence of traffic congestion at locations where traffic congestion of 30 km or more occurred in the past showed that, on the Tohoku Expressway etc., compared to 2004, before the introduction of the ETC-only discount system for Expressway As a result, there was a change in traffic volume in some time zones, such as an increase in traffic volume at night. Also, in some parts of the Tohoku Expressway, there were days when traffic jams decreased significantly due to changes in traffic volume, although the daily traffic volume was almost the same as in 2004. It is considered that the introduction of the ETC time zone discount system has contributed to one of the factors to alleviate traffic congestion.

To alleviate this traffic congestion, customers who traveled in a relatively lightly crowded time zone could use various time zone discounts such as "ETC midnight discount" and "ETC early morning and night discount" implemented in areas such as Tokyo. I can guess that it was because there were many. The ETC time zone discount allows you to drive comfortably without getting caught in traffic jams, It also helps alleviate traffic congestion Please use it effectively in the future.

3 Alleviation of traffic congestion due to traffic concentration in sags

In-bound hill or sag part ^*1 In, In-bound there is the travel speed is reduced unconsciously when approaching the hill, congestion occurs. To alleviate such traffic congestion, especially in areas where a large traffic congestion is expected, Marked cars with excellent visibility (LED ^*2 "Providing speed recovery information" using a sign car The we.

Near the Tohoku Expressway Out-bound Hanyu Parking Area (PA) where this measure was taken, and near the Kan-Etsu Expressway In-bound Hanazono Interchange (IC), The daily traffic volume was almost the same as before the measures, or increased, but the traffic congestion decreased. Did.

"Providing speed recovery information using LED-marked vehicles" will alleviate traffic congestion at a low cost, so we will continue to implement it.
