1. Mobility in its Different Modes, and the Transportation Systems That Enable It Assistant Professor, Graduate School of The Quality and Quantity of a Engineering, University of Tokyo 1-1 Changing Mobility Kiyoshi Takami We now have the basic data on the movement of people and goods. In regards to the flow of people, in recent years, the number of trips per person is on an upward trend, while the distance traveled is on a gradual decrease . The data also reveals an upward trend in the motor vehicle share of trips of the elderly and women, and in the number of private trips. Regarding the flow of goods, the tonnage per person has been constantly decreasing since the latter half of the ‘90s; transportation in ton-kilometers has been almost flat although there some periodicity is observed. In ton-kilometers, the share of motor vehicles is increasing noticeably. □ Passenger transportation in the past 35 years. In regards to motor vehicles, the number of trips and the distance traveled per person per year have been generally increasing, although the distance traveled started to decrease from FY 1999, then became stable. Railways, after their peak in the early 90’s, decreased to the lowest level in FY 2004, then began another upward trend. There has been a near- constant decrease in travel on passenger ships, and an increase in air travel, but for the past several years, both have remained almost stable. The cumulative total of all those transportation modes shows that the number of trips has been generally on an upward trend, while the distance traveled has shown a generally downward trend.

In annual transportation ton-kilometers per person, there is an upward trend for motor vehicles and a downward trend for coastal shipping; for railways and aircraft, the figures have been flat for the last ten years or so.

This tendency is more noticeable in local city areas than in the three major metropolitan areas. The modal share of motor vehicle by females aged 25 to 44 in local city areas has increased to that of males.

Mobility in its Different Modes, and the Transportation Systems That Enable It Road Network Today Chief Researcher, The Institute of Behavioral Sciences 1-2 Tsutomu Yabe The length of our roads has been steadily extended thanks to ongoing road improvement, yet it is not still sufficient for traffic demand. As a result, the average speed on roads remains unchanged at a lower level. A case in point: in city centers such as Tokyo and Osaka, and in DID(Densely Inhabited District) areas , there is still chronic traffic congestion. Given that background, road network improvements (e.g., the ring road improvement plans that are proceeding in the three major metropolitan areas) are obviously playing a significant role. Fig. 1 Changes in the length of completed roads by road type Fig. 2 Changes in traffic volume and road length ■ For all types of roads, the length of completed road (i.e., with ■ The figure for traffic volume in vehicle-kilometers, after improvements completed) is increasing steadily. peaking in 2001, is on a downward trend; but the figure for light motor vehicles is on an upward trend.
