Quantifying Incidental Bicycle & Pedestrian Costs in Highway Projects

Bicycle and pedestrian infrastructure is growing in importance to the public, and increasingly being incorporated into highway and bridge projects. However, systems have not been in place to track "incidental" expenses for bicycle and pedestrian accommodations within highway, bridge and interchange projects. This has made it difficult to understand the scope of the bicycle and pedestrian elements such as bicycle lanes, pedestrian sidewalks and bridge widening that has been included in highway projects and the cost of those improvements. Incidental bicycle and pedestrian costs are those costs included in the budgets of larger, scheduled highway improvement projects. They can include bicycle lanes, sidewalks, intersection improvements, and widened shoulders. Adding pedestrian accommodations to bridges requires additional bridge width, increasing their structural costs. Projects funded exclusively for bicycle and pedestrian improvements (considered "independent" bicycle and pedestrian projects) are not included in this research. A detailed analysis of incidental bicycle and pedestrian expenses or guidance on quantifying incidental costs for bridge accommodations was not available to researchers or other interested groups. This report attempts to fill in these gaps and provide guidance and greater understanding of incidental expenses for bicycle and pedestrian elements. An accurate cost calculation for incidental bicycle and pedestrian expenditures requires both a detailed accounting of all identifiable bicycle and pedestrian costs by category and an estimate of the additional costs associated with bridge elements. Whether a bridge was widened to accommodate pedestrians is not routinely tracked as part of project cost data, so those data were gathered and calculated in a separate process, with the results incorporated into the final total cost calculations.
