Rapid City's growth demands infrastructure expansion. Sheridan Lake Road, a vital route in the area, undergoes significant widening to accommodate increased traffic volumes and pedestrians. With completion expected this fall, the $15.5 million project stays on budget despite challenges, ultimately enhancing transportation efficiency for residents and visitors....

TDOT's $69.4M widening of Summer Avenue in Memphis, a project 25+ years in the making, focuses on traffic flow and safety. The 2-mile expansion adds lanes, bridges, bike paths, and sidewalks, anticipating completion by June 2028 after decades of planning and delays....

The Placer County Fiscal Court unanimously authorized an emergency exemption to spend federal and state road grants that would otherwise count against a year-end 65% spending cap, citing a November deadline on one federal grant.

County finance staff presented a preliminary 2027 budget with a total appropriation of $3,940,989.18 and a proposed net mill change of -1.09; commissioners extensively debated using permit-fund revenue to pay off road equipment leases now or retain lease payments to preserve 3% cap capacity next year.

NCDOT presented crash data showing 19 crashes (including one fatality) at NC 118 intersections since 2021 and proposed removing direct access from Cannon Price Road, installing a cul‑de‑sac, and building a single‑lane roundabout at St. Johns Road; the board voted to support the project so DOT can pursue scoring and funding.

Grant County commissioners unanimously approved resolution R-26-37 to place two general‑obligation bond questions (total $8,000,000; $4M public facilities, $4M roads) on the 2026 general election ballot, and presenters said the proposal is structured to avoid raising the current tax rate if voters approve it.

<p>काठमाडौँ– निर्माण सुरु भएको करिब सात वर्षपछि नेपालकै पहिलो आधुनिक सडक सुरुङमार्ग (नागढुंगा–सिस्नेखोला सुरुङमार्ग) औपचारिक रूपमा सञ्चालनमा आएको छ। सुरुङ उद्घाटनसँगै तत्कालीन प्रधानमन्त्री केपी शर्मा...

The association has urged authorities to improve traffic flow and speed up road repairs to ensure smoother cargo movement across the port ecosystem.

A newly opened fixed link to the mainland has created hazardous conditions for cyclists on Hailuoto island, with drivers overtaking too closely on the narrow Luovontie road, Yle reports. The bridge, inaugurated in late June, has replaced ferry-based traffic, leading to a steady stream of vehicles…

Following recent flash floods, residents urged action on unmaintained roads and drainage; county staff explained the 80% frontage petition threshold, 50‑foot ROW requirement and up to 50% county funding for special assessments, while commissioners discussed lowering thresholds, FEMA buyouts and a stormwater workshop.

The fiscal court voted to advertise a $600,000 budget amendment to pass through funds for a senior-housing conversion project and approved a separate $561,000 flex funding resolution for road/asphalt work, both by voice vote.

Researchers conducted an extensive real-world study using a Tesla Model Y equipped with Full Self-Driving (FSD) software over more than 100 days on Queensland roads in Australia. Across this period, they recorded over 500 safety-critical events requiring human intervention or revealing significant limitations in the system’s perception and decision-making abilities. While the technology demonstrated impressive capabilities in many routine driving scenarios—often matching or exceeding human precision—it also showed consistent weaknesses in common and complex traffic environments. Key problem areas included confusion at small bridges, misinterpretation of time-restricted speed zones such as school areas, and unsafe handling near railway crossings where the system failed to adequately anticipate risk. Complex urban conditions such as roundabouts, poorly marked streets, and interactions with cyclists or e-scooter users also frequently led to errors. Weather conditions that obscured lane markings further reduced system reliability. Notably, none of the test journeys were completed without at least one human intervention, highlighting that current systems are not yet fully autonomous in real-world Australian conditions. The study argues that the challenge is not solely technological but also infrastructural. Many road features designed for human interpretation—such as inconsistent signage, faded markings, and ambiguous intersections—contribute to machine errors. The researchers suggest that improving road infrastructure, standardising signage, and enhancing lane clarity could significantly improve autonomous vehicle performance. They also propose a complementary role for autonomous vehicles as mobile sensing platforms capable of detecting potholes, damaged signage, and congestion patterns in real time. Rather than viewing autonomous vehicles as entirely independent systems, the study advocates for a hybrid approach in which smarter vehicles and smarter infrastructure evolve together. The findings highlight that widespread deployment of autonomous driving in Australia will require coordinated improvements in both vehicle intelligence and road system design.

At its March 19 meeting in Marshall, Calhoun County commissioners approved short-term delinquent tax notes, awarded multiple road-construction and pothole-patching contracts (including Lakeland Asphalt for 2026 paving), and authorized a Michigan Natural Resources Trust Fund grant application for a new trailhead providing access to 256 acres at the MAJOR Campus.

The Transportation Advisory Committee set a schedule and began prioritizing projects for a potential November referendum to raise funds for road work; the county engineer estimated tourists could pay roughly 60% of a proposed sales tax, and the committee will continue community outreach.
