Evaluating Accessibility to parking lots

A store owner in an area where public transportation network is not very developed wants to grasp his store’s site condition considering car access, because residents of such an area usually move by private car. In this situation, evaluating accessibility for parking lots must not be overlooked. In this article, we will show a simulation for evaluating accessibility to parking lots. There are 7 Ome municipal parking lots and 6 private parking lots in this area. The following illustration represents mapping of these parking lots. In the simulation, we presume that visitors of this area park their cars in the closest parking lot from the present place. We set initial condition […]

Evaluating Openness index of streets.

We can consider “Openness of street” as one conventional comfort index. In order to evaluate this index, we emit rays from a certain point, and calculate the number of rays which can reach the sky without being obstructed by the other buildings or trees. By carrying out calculations on whole points in a street, we can draw a distribution of “Openness index”. This Openness index is useful for simulate the influence toward surround buildings, and we can use this simulation when designing new buildings.

Evaluating shopping streets–Local cooperation between existing stores and new stores

There are many cases where it is difficult to refurbish vacant stores in some area simultaneously. In this cases, what order should we refurbish that vacant stores? We propose new index for this situation from the point of view of local cooperation between existing stores and new stores. In this article, we focus on restaurants and give priority to these vacant stores. First of all, we find out actual street network from existing stores and streets. This actual street network is not so call shopping streets but “VITAL” shopping street. Later, we calculate betweenness centrality of vital street network when people visit each store in the area. (High rated nodes […]

Evaluating accessibility based on min-sum distance weighted by population distribution

In this article, we try to evaluate accessibility based on min-sum distance weighted by population distribution in Ome, Tokyo. We can basically say that the population of certain place is directly proportional to a gross area of certain building. Therefore, we can add values of population to each nodes. To consider the outside population distribution of this area, we divide outside area into 6 super nodes, and add the values as attributes.
