The purpose of this paper is to find the relation .between urban region and road, from the quantitative analysis of actual data. (1) The relation between ratio of total area of urban regions to that of the whole region observed U and density of road (which is a ratio of total length of road to total area of urban regions) W was expressed by W=a+bU where a and b are parameters. The reration between the W and density of urban regions (which is a ratio of number of urban regions to the whole region observed) N was also expressed by W=a'+b'N. where a' and b' are parameters. According to these results, it was concluded that road was closely related with urban region. (2) The relation between population density of urban region D and the road density supplied to urban region (which is a ratio of total length of road in a region observed to the total area of urban region in a region observed) W_u are observed. And the relation was expressed by W_u=γ_0+γ_1D γ_1>0 in agricultural regions, and by W_u=γ_0'+γ_1'D γ_1'<0 in industrial regions, where γ_0, γ1, γ0' and γ_1' are parameters. Incidentally, the regions observed are classified into two kinds of regions, agricultural and industrial regions. And, the models written above are derived from the following model under some additional conditions. L_<Dt>=a_0+a_1P_<ut-1>+a_2A_<ut> P_<ut>=b_0+b_1L_<st>+b_2A_<ut> L_<St>=g_0+g_1L_<Dt> where L_<Dt> is the length of road demanded in a region at time t, L_<St> the length of road supplied in a region at time t, P_<ut> the population in a region at time t, A_<ut> the total area of all urban regions at time t, and a_j, b_j, (j=0, 1, 2) and g_k (k=O, 1) are parameters.
