The growing number of private transportation ownership yearly creates congestion problems, especially in urban areas. Public transportation conditions such as Rapid Transit Bus (BRT) are an alternative use of transportation. BRT Trans Semarang Corridor 1 is the busiest Trans Semarang Bus route compared to other routes, this corridor departs from Mangkang Terminal to Penggaron Terminal. The results of previous research samples show that 50% of the passengers of BRT Trans Semarang Corridor 1 chose to walk to and from the bus stops. However, the current condition of the pedestrian paths is less optimal in creating pedestrian comfort, such as the lack of shady vegetation to designs that do not meet the standard needs of the user and the integration system is still minimal with various modes. The purpose of this study is to identify a travel need model such as design and ease of access in accordance with the pedestrian travel demand of BRT Trans Semarang Corridor 1 passenger using the new 3D urbanism approach (Density, Diversity, Design). Density analysis uses descriptive statistical analysis methods and simulates the interpolation of population data and building density using the ArcGIS 10.3 application to generate pedestrian needs such as pedestrian design or elements of pedestrian paths and access to pedestrian paths to environmental density. Analysis of the diversity was performed using the land-use distribution simulation method with ArcGIS 10.3 and FAR (Floor Area Ratio) analysis was performed using the 2016 Sketchup simulation. Compile a pedestrian path model recommendation under pedestrian demand.
