whilst private light vehicles can also use it, they are only permitted to pass through the lane. Other roads with motorcycle lanes include Commonwealth Avenue and Quezon Avenue, both in Quezon City, Diosdado Macapagal Boulevard in Pasay and Parañaque and Circumferential Road 5. Taiwan United Kingdom Generally, motorcycles are treated the same as any other vehicle. However, as of January 2012, Transport for London have made the numerous bus lanes in London permanently accessible to motorcyclists, after two trials were undertaken suggesting that this policy will lead to decreased congestion, decreased carbon emissions and safer city center journeys for motorcyclists. Safety issues in Malaysia While the design of the motorcycle lanes on some federal roads in Malaysia can be considered as acceptable, the design of motorcycle lanes on expressways is often criticized by Malaysian motorcyclists due to several issues. Design and maintenance The chief reason that had contributed to the design-related criticisms of the segregated motorcycle lanes on expressways is the adoption of the design standards of segregated bicycle lanes, namely the standards defined by Arahan Teknik (Jalan) 10/86: A Guide to the Design of Cycle Track by Malaysian Public Works Department. According to Arahan Teknik (Jalan) 10/86: A Guide to the Design of Cycle Track, the typical design speed limit being applied on cycle tracks is as low as 60 km/h. However, the design speed limit is too low, as the reported 85th percentile operating speeds of motorcyclists along the motorcycle lanes at the Federal Highway during peak hours and non-peak hours are 72 km/h and 80 km/h respectively. Due to the operating speeds almost the same as the speed limit of the main carriageways itself, T. H. Law et al. (2005) suggest that the minimum width of the segregated motorcycle lane at the Federal Highway should be set at 3.81 m. However, the average width the existing segregated motorcycle lanes, such as that which is located on the Federal Highway, is only two meters wide. The width of the motorcycle lane is too narrow for bigger motorcycles, as well as for the purpose of overtaking. According to G. Ramasamy, one of the engineers being responsible for the construction of the Federal Highway between 1974 and 1977, he explained that the constructors built a pair of cycle tracks along the highway to segregate the bicycle traffic from the main carriageways. However, he was shocked to find out that the
