Ecosphere 7(4):e01345. 10.1002/ecs2.1345 Abstract. Roads, while central to the function of human society, create barriers to animal movement through collisions and habitat fragmentation. Barriers to animal movement affect the evolution and tra- jectory of populations. Investigators have attempted to use traffic volume, the number of vehicles passing a point on a road segment, to predict effects to wildlife populations approximately linearly and along taxonomic lines; however, taxonomic groupings cannot provide sound predictions because closely related species often respond differently. We assess the role of wildlife behavioral responses to traffic volume as a tool to predict barrier effects from vehicle-caused mortality and avoidance, to provide an early warning system that recognizes traffic volume as a trigger for mitigation, and to better interpret roadkill data. We propose four categories of behavioral response based on the perceived danger to traffic: Nonresponders, Pausers, Speeders, and Avoiders. -
Preferential and Managed Lane Signs and General Information Signs
2009 Edition Page 253 CHAPTER 2G. PREFERENTIAL AND MANAGED LANE SIGNS Section 2G.01 Scope Support: 01 Preferential lanes are lanes designated for special traffic uses such as high-occupancy vehicles (HOVs), light rail, buses, taxis, or bicycles. Preferential lane treatments might be as simple as restricting a turning lane to a certain class of vehicles during peak periods, or as sophisticated as providing a separate roadway system within a highway corridor for certain vehicles. 02 Preferential lanes might be barrier-separated (on a separate alignment or physically separated from the other travel lanes by a barrier or median), buffer-separated (separated from the adjacent general-purpose lanes only by a narrow buffer area created with longitudinal pavement markings), or contiguous (separated from the adjacent general-purpose lanes only by a lane line). Preferential lanes might allow continuous access with the adjacent general-purpose lanes or restrict access only to designated locations. Preferential lanes might be operated in a constant direction or operated as reversible lanes. Some reversible preferential lanes on a divided highway might be operated counter-flow to the direction of traffic on the immediately adjacent general-purpose lanes. 03 Preferential lanes might be operated on a 24-hour basis, for extended periods of the day, during peak travel periods only, during special events, or during other activities. 04 Open-road tolling lanes and toll plaza lanes that segregate traffic based on payment method are not considered preferential lanes. Chapter 2F contains information regarding signing of open-road tolling lanes and toll plaza lanes. 05 Managed lanes typically restrict access with the adjacent general-purpose lanes to designated locations only. -

This makes them brittle and potentially un- encoder safe in situations that do not match training data. Here, we propose to address this issue by augmenting training control data with natural language advice from a human. Advice commands includes guidance about what to do and where to attend. Visualizing We present a first step toward advice giving, where we train without advice with advice model’s attention an end-to-end vehicle controller that accepts advice. The controller adapts the way it attends to the scene (visual attention) and the control (steering and speed). Attention Figure 1: Our model takes human-to-vehicle advice as an mechanisms tie controller behavior to salient objects in the input, i.e., “pedestrians are in crosswalk”, and grounds it advice.

Shared Streets and Alleyways – White Paper
City of Ashland, Ashland Transportation System Plan Shared Streets and Alleyways – White Paper To: Jim Olson, City of Ashland Cc: Project Management Team From: Adrian Witte and Drew Meisel, Alta Planning + Design Date: February 2, 2011 Re: Task 7.1.O White Paper: “Shared Streets and Alleyways” - DRAFT Direction to the Planning Commission and Transportation Commission Five sets of white papers are being produced to present information on tools, opportunities, and potential strategies that could help Ashland become a nationwide leader as a green transportation community. Each white paper will present general information regarding a topic and then provide ideas on where and how that tool, strategy, and/or policy could be used within Ashland. You will have the opportunity to review the content of each white paper and share your thoughts, concerns, questions, and ideas in a joint Planning Commission/Transportation Commission meeting. Based on discussions at the meeting, the material in the white paper will be: 1) Revised and incorporated into the alternatives analysis for the draft TSP; or 2) Eliminated from consideration and excluded from the alternatives analysis. The overall intent of the white paper series is to explore opportunities and discuss the many possibilities for Ashland. Shared Streets Introduction Shared Streets aim to provide a better balance of the needs of all road users to improve safety, comfort, and livability. They are similar to European concepts such as the Dutch based ‘Woonerf’ and the United Kingdom’s ‘Home Zone’, with some distinct differences. This balance is accomplished through integration rather than segregation of users. By eschewing many of the traditional roadway treatments such as curbs, signs, and pavement markings, the distinction between modes is blurred. -
Reversible Traffic Lanes
Traffic Management System Efficiency Reversible Traffic Lanes REVERSIBLE TRAFFIC LANES Description Reversible traffic lanes add capacity to a road and decrease congestion by borrowing capacity from the other (off- peak) direction. Reversing lanes reduces congestion during morning and evening commutes, when there is an incident blocking a lane of traffic, or when construction or maintenance is being done on the road. Roads can be adjusted to become a one- way street or have one middle lane operate in the peak direction. These adjustments, indicated by changeable message signs and/or Cost: arrows, occur at specified times of the day or when volume Time: Short exceeds certain limits. Impact: Corridor Target Market Who: City/State . Congested work zone areas or during incidents Hurdles: Public Awareness/ . Roads with highly directional congestion Operation . Bridges, tunnels, and toll booth areas difficult to widen . Surrounding or leading to/from special event centers Reversible lanes work well in corridors where traffic flow is heavily imbalanced for a short period of time, and there are few other solution options. How Will This Help? . Reduce congestion by temporarily “borrowing” capacity from the other direction. Increase safety in work zones. Postpone the need to add capacity through conventional lane additions. Implementation Issues Success Story Proper communication and public participation are crucial to Arlington, Texas, installed reversible ensuring the strategy’s success.

Indiana Drivers Manual: Ch. 7
CHAPTER 7 | Safe Vehicle Operation CHAPTER SEVEN | SAFE VEHICLE OPERATION Even the most experienced drivers can be distracted while driving. A defensive driver looks out for the actions of other drivers and anticipates potential problems. LANE MARKINGS Lane markings separate traffic and alert drivers when it is permissible to pass other vehicles. Yellow Lane Markings Yellow lane markings separate multiple lanes of traffic going in opposite directions. You may cross a broken yellow line to pass another vehicle when it is safe, but you should not cross a solid yellow line except to turn. Two-lane road with a solid yellow line Two-lane road with a broken Four-lane road with a solid yellow line yellow line White Lane Markings White lane markings separate multiple lanes of traffic going in the same direction. Most roads with more than two lanes have broken white lines to separate the lanes. You may cross a broken white line when it is safe to change lanes, but you should not cross a solid white line. Three lanes of traffic with broken white lines CHANGING LANES AND PASSING OTHER VEHICLES Change only one lane at a time. When changing lanes to prepare for a turn, you must signal your intention to do so at least 200 feet prior to changing lanes or turning. Your signal distance must be at least 300 feet before the turn if you are operating a vehicle in a speed zone of at least 50 miles per hour. Do not weave in and out of lanes, which will greatly increase your risk of an accident.
