• Authors: Tyler Saxton
• Abstract summary: This thesis presents a method to create a map of bicycle lanes in a survey area by taking sample street scene images from each road. A deep learning model that has been trained to recognise bicycle lane symbols is applied. The method was applied to successfully build a map for a survey area in the outer suburbs of Melbourne.

• Abstract: On-road bicycle lanes improve safety for cyclists, and encourage participation in cycling for active transport and recreation. With many local authorities responsible for portions of the infrastructure, official maps and datasets of bicycle lanes may be out-of-date and incomplete. Even "crowdsourced" databases may have significant gaps, especially outside popular metropolitan areas. This thesis presents a method to create a map of bicycle lanes in a survey area by taking sample street scene images from each road, and then applying a deep learning model that has been trained to recognise bicycle lane symbols. The list of coordinates where bicycle lane markings are detected is then correlated to geospatial data about the road network to record bicycle lane routes. The method was applied to successfully build a map for a survey area in the outer suburbs of Melbourne. It was able to identify bicycle lanes not previously recorded in the official state government dataset, OpenStreetMap, or the "biking" layer of Google Maps.

• Classifying Bicycle Infrastructure Using On-Bike Street-Level Images [0.0]
  Many potential cyclists are discouraged from taking up cycling due to the lack of suitable and safe infrastructure. We propose a system capable of classifying available cycling infrastructure from on-bike smartphone camera data. This work is the first to classify cycling infrastructure using only street-level imagery collected from bike-mounted mobile phone cameras.

  We present a mapping system that fuses local submaps gathered from a fleet of vehicles at a central instance to produce a coherent map of the road environment. Our method jointly aligns and merges the noisy and incomplete local submaps using a scene-specific Neural Signed Distance Field. We leverage memory-efficient sparse feature-grids to scale to large areas and introduce a confidence score to model uncertainty in scene reconstruction.

  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.

  We introduce LaneSegNet, the first end-to-end mapping network generating lane segments to obtain a complete representation of the road structure. Our algorithm features two key modifications. One is a lane attention module to capture pivotal region details within the long-range feature space. On the OpenLane-V2 dataset, LaneSegNet outperforms previous counterparts by a substantial gain across three tasks.

We evaluate various state-of-the-art methods, and present their quantitative and qualitative results on OpenLane-V2 to indicate future avenues for investigating topology reasoning in traffic scenes.

  We introduce Pix2Map, a method for inferring urban street map topology directly from ego-view images. This problem can be posed as cross-modal retrieval by learning a joint, cross-modal embedding space for images and existing maps. We show that our retrieved maps can be used to update or expand existing maps and even show proof-of-concept results.

  We focus on drawing the lane boundaries of complex highways with many lanes that contain topology changes due to forks and merges. We formulate the problem as inference in a directed acyclic graphical model (DAG), where the nodes of the graph encode geometric and topological properties of the local regions of the lane boundaries. We show the effectiveness of our approach on two major North American Highways in two different states and show high precision and recall as well as 89% correct topology.

  We study an urban bike lane planning problem based on the fine-grained bike trajectory data made available by smart city infrastructure such as bike-sharing systems. As bike-sharing systems become widespread in the metropolitan areas over the world, bike lanes are being planned and constructed by many municipal governments to promote cycling and protect cyclists. We develop tractable formulations and efficient algorithms to solve the large-scale optimization problem.
