<br /> Public Rights-of-Way Evaluation
<br />Prior to initiating the public right-of-way (PROW) portions
<br />of the contract, BV will confirm the list of sidewalks, streets,
<br />and curb ramps that will be analyzed. If sidewalk locations
<br />are not known, BV will take a strategic approach using
<br />the GIS street network to ensure a complete dataset is
<br />collected.
<br />
<br />BV will systematically survey the sidewalk surface
<br />environment for compliance with state, local, and federal
<br />accessibility standards. BV will document changes in level,
<br />roughness, running slope, cross slope, width, and other
<br />pathway events that may pose a barrier in the pedestrian
<br />network. Objective sensor-based data along with
<br />technician observed barriers will be recorded. BV will assess
<br />curb ramps for ADA compliance, measuring necessary
<br />attributes, including but not limited to running slope,
<br />cross slope, landings, flares, and detectable warnings.
<br />Image documentation of all curb ramps will be provided.
<br />The barriers of each curb ramp or the lack of a curb ramp
<br />will be documented. BV will capture deficiency data for
<br />transit stops, signalized intersections, and unsignalized
<br />intersections, including access to pedestrian pushbuttons
<br />and the condition and presence of markings.
<br />
<br />The PROW survey will begin in those priority areas that
<br />received the highest rank and will then extend to the
<br />other areas which are part of the rights-of-way list. This
<br />evaluation will identify and record any gaps in connectivity,
<br />potential safety hazards, obstructions, missing curb ramps,
<br />and general noncompliance with accessibility regulations,
<br />including the following:
<br />• Assessment of the Pedestrian Right of Way (Sidewalks)
<br />• Assessment of Curb Ramps
<br />• Assessment of Pedestrian Crossings, Signalized
<br />Intersections, Un-signalized Intersections
<br />
<br />Public Rights of Way Assessment Technology
<br />The BV team will utilize proprietary technology to efficiently
<br />and accurately assess the conditions that exist in the
<br />sidewalk environment within the City’s jurisdiction. An
<br />assessment coordinator utilizes a manually-propelled
<br />sensor-based device (or in some cases an autonomous
<br />robotic device) to systematically evaluate the sidewalk
<br />surface. The device automates the process of identifying
<br />important pathway measurements for ADA compliance and
<br />infrastructure management, including:
<br />a) level changes (tripping hazards);
<br />b) running slope;
<br />c) cross slope;
<br />d) WPRI roughness;
<br />e) width (including pinch points);
<br />f) images every ten feet;
<br />g) low clearances;
<br />h) presence of obstructions;
<br />i) presence of vegetation;
<br />j) presence of other manually flagged attributes; and other
<br />qualitative attributes.
<br />
<br />If required, one of our technology devices is uniquely
<br />qualified to measure wheelchair pathway roughness index
<br />(WPRI) according to ASTM E3028 (standard development
<br />funded by the Access Board).
<br />
<br />The technology utilizes lasers, inertial measurement
<br />sensors, and HD cameras to facilitate data collection
<br />of all necessary measurements. It supports sidewalk,
<br />crosswalk, and public right-of-way data collection up to
<br />five times faster than standard methods (tape measures
<br />and levels), while providing the best data. Unlike other tools
<br />and software, our technology delivers continuous data
<br />rather than individual points of only tripping hazards and
<br />obstructions on a map. This means that the City receives
<br />the most complete dataset without missing any part of the
<br />pedestrian network.
<br />
<br />BV gathers all of the typical curb ramp, pedestrian signal,
<br />and bus stop measurements for ADA compliance, including
<br />but not limited to:
<br />a) running and cross slopes;
<br />b) lengths and widths;
<br />c) detectable warning surfaces;
<br />d) landing measurements;
<br />e) presence of obstructions;
<br />f) photos; and other configurable measurements and
<br />qualitative attributes.
<br />
<br />Federal, state, or local curb ramp types are utilized as
<br />a guide to facilitate data collection of all necessary
<br />measurements. Our technology supports data collection
<br />up to six times faster than standard methods, providing
<br />the best data. Unlike Lidar collection methods, which can
<br />have difficulty measuring slopes the technology provides
<br />accurate slope and distance measurements comparable
<br />to the standard tape measure and digital level. Its unique
<br />rating index, which is customizable, makes it easy to
<br />prioritize improvements, delivering data-driven results, and
<br />saving time and money.
<br />
<br />PROW Deliverable
<br />All data is delivered in a GIS-compatible format (.gdb or
<br />.shp), making it easy to integrate into the City’s GIS software
<br />enabling easy data-driven decision-making. Data may be
