前言修建造型美观的道路,在科技工作者中尚未成为量重要的课题。道路不同于其他那些具有重要功能的结构物,难以用数字来评价它。道路比绘画、雕刻或建筑物的规模大,在事先要直观地评定它是困难的。然而,随着经验的积累和电子计算机的发展,已经有可能研究这些方面的问题了。对比过去,用同样的投资,或稍追加少量投资就能建成更加美观的道路,业已屡见不鲜。

However, with the accumulation of experience and the development of electronic computers, it has been possible to study these issues. Compared to the past, with the same investment, or a small additional investment can build a more beautiful road, has been uncommon.
