The Bike Trail User Model estimates bicycle and pedestrian use on shared-use paths and bike lanes at Lake Tahoe. The model is based on observed facility use, characteristics of individual facilities, and user demographics and travel behaviors. Click here for instructions on how to use the model or here for a full model demonstration.

The Active Transportation Infrastructure Buffer Zone Map helps people identify if their projects are within the 75-foot buffer zone of an existing or proposed active transportation facility. If a project is within the buffer, the project must be designed to accommodate active transportation facilities. Using this map, people can view bike routes, dirt trails, and special assessment districts by parcel number.


Identifying and analyzing trends are at the core of any planning effort. Working with its many partners, TRPA monitors a number of performance indicators and also maintains demographic and socio-economic data. In December of 2012, the TRPA Governing Board approved the Lake Tahoe Regional Transportation Plan and Sustainable Communities Strategy (Mobility 2035). Our latest reports include: Mobility 2035: Transportation Monitoring Program Report and 2015 Bicycle & Pedestrian Monitoring Report
