• Abstract summary: Street-level bicycle volume information would aid cities in planning targeted infrastructure improvements to encourage cycling. The data currently available to cities and citizens often only comes from sparsely located counting stations. This paper extrapolates bicycle volume beyond these few locations to estimate bicycle volume for the entire city of Berlin.

• Abstract: Shifting to cycling in urban areas reduces greenhouse gas emissions and improves public health. Street-level bicycle volume information would aid cities in planning targeted infrastructure improvements to encourage cycling and provide civil society with evidence to advocate for cyclists' needs. Yet, the data currently available to cities and citizens often only comes from sparsely located counting stations. This paper extrapolates bicycle volume beyond these few locations to estimate bicycle volume for the entire city of Berlin. We predict daily and average annual daily street-level bicycle volumes using machine-learning techniques and various public data sources. These include app-based crowdsourced data, infrastructure, bike-sharing, motorized traffic, socioeconomic indicators, weather, and holiday data. Our analysis reveals that the best-performing model is XGBoost, and crowdsourced cycling and infrastructure data are most important for the prediction. We further simulate how collecting short-term counts at predicted locations improves performance. By providing ten days of such sample counts for each predicted location to the model, we are able to halve the error and greatly reduce the variability in performance among predicted locations.

  We present the first study to utilize a Graph Convolutional Network architecture to model link-level bicycling volumes. We estimate the Annual Average Daily Bicycle (AADB) counts across the City of Melbourne, Australia using Strava Metro bicycling count data. Our results show that the GCN model performs better than these traditional models in predicting AADB counts.

  We introduce a modelling framework to predict the service times of deliveries based on urban context.

GeoVex represents micro-regions as points in a continuous vector space, which then serve as input for predicting vehicle service times.

• Estimating city-wide hourly bicycle flow using a hybrid LSTM MDN [0.0]
  Efforts to increase the bicycle's mode-share involve many measures, one of them being the improvement of cycling safety. meaningful analysis of cycling safety requires accurate bicycle flow data that is generally sparse or not even available at a segment level. This paper presents a Deep Learning based approach, to estimate hourly bicycle flow in Copenhagen, conditional on weather, temporal and road conditions.

  We develop the IPDC procedure (Identify, Prioritize, Decluster, Classify) for finding the most important missing links in urban bicycle networks. We first identify all possible gaps following a multiplex network approach, prioritize them according to a flow-based metric, decluster emerging gap clusters, and manually classify the types of gaps. Our results show how network analysis with minimal data requirements can serve as a cost-efficient support tool for bicycle network planning.
